TIMBER FRAMERS GUILD - 2018 WESTERN CONFERENCE - Timberline Lodge, Mt. Hood

Timber Framers Guild | 1106 Harris Ave, Suite 303 | Bellingham, WA 98225 | 360-746-6571

For thirty-three years now, without missing a beat, the Timber Framers Guild has gathered the tribe for our annual conference, and for at least the fifth time, we are gathered on the slopes of Mount Hood in one of the very best buildings on the planet—Timberline Lodge. Welcome!

The Guild works because members get involved, and events like these are a team effort. Megan Starr, TFG program director has worked with a talented bunch of folks including Michael Cuba, Autumn Peterson, Jonathan Orpin, Jennifer Anthony, and Brenda Baker to put together an outstanding line up of presentations. And, we would be remiss not to mention that the Timber Frame Engineering Council has prepared an exceptional sequenced series of presentations.

These events also happen because of generous contributions from our sponsors. They help to make these events affordable, and so we encourage you to thank them, but better yet, buy stuff from them! Our national conference sponsor is Foard Panel. Elk Creek Forest Products is our western conference sponsor. Pioneer Millworks is sponsoring the ax throwing fandango. If you wet your whistle at the auction, thank Fraserwood Industries. The marketing firm, Ketchup & Mustard, contributed the design of our conference logo. Heritage Natural Finishes is sponsoring the Girls Build Program. And last but certainly not least, pFreim Family Brewers is kicking in beer for our speakers. How about that for a perk?

It’s always a challenge to pull together content for as diverse a group as the Timber Framers Guild, but we believe this conference sports an excellent line up. We go from basic tools use and techniques, many of which would be familiar to carpenters from the 14th-century, to the complexities of high performance buildings. Wow. Hold onto your hats!

Looking over the registration list, we note that at least 40 of you are here for your first Guild conference. Welcome, welcome, welcome! From the very beginning, sharing knowledge was at the heart of the Timber Framers Guild, and now into our fourth decade, the TFG has evolved into a unique learning community. We hope that you find, as many TFG members have found, life-long learning opportunities and a network of special folks.

Sincerely,

Your TFG Board of Directors TABLE OF CONTENTS

6 FEATURED PRESENTATIONS

GARY ROGOWSKI Friday, June 1, 9:30 a.m. – 10:30 a.m.

WHEN HAMMER MEETS THUMB: CREATIVITY AND FORGIVENESS

To work with our hands can be a difficult choice in this age of immediacy, the quick, the ephemeral. This path requires patience, it takes time, it demands focus. It is presumed to be the bailiwick of simpler minds not suited to creative thought. Gary Rogowski, furniture maker, author, and teacher, has another point of view in this our digital age.

His new book is entitled: Handmade: Creative Focus in the Age of Distraction. Please join us for his discussion on the value of doing work as if it mattered, on taking a chance on our creativity, and for using our hands to help us think and engage with the world. His book argues for the need for individuals and for cultures, if they are to remain creative, to stay curious and engaged with the physical world as a means of thinking more clearly. He will address the value of failure and the need for forgiveness in any journey to becoming a master. Part memoir, part stories from the bench, these stories speak to us all.

BRUCE KING Saturday, June 2, 10:30 a.m. – 11:30 a.m. THE NEW CARBON ARCHITECTURE

Bruce will portray the fast growing movement to build with carbon, especially with plants from enzymes to mushrooms to straw to mass timber. Timber framing is poised to make a huge contribution to this shifting of the built environment from a greenhouse gas emitter to a carbon sink, and we can all play a big role as climate champions.

THOMAS ROBINSON Saturday, June 2, 3:45 p.m. – 4:45 p.m. WHAT IS CRAFT AND HOW DO WE CONNECT TO ARCHITECTURE?

In every project, we work to create spaces that transcend documentation and photography to create elevated experiences that are singular and connected to material and making. Timberline Lodge is highly relevant as an example of this synthesis of craft, structure, and art. The experience of the Lodge is difficult to evaluate without being physically present in the space, and is the result of many layers of design, labor, and craft. As we utilize new technologies and methods that remove the hand directly from making, what is craft and how do we connect to architecture? Thomas will share his personal experience working at the intersection of making and architecture through the lens of LEVER’s current and speculative work. This includes Albina Yard, LEVER’s office and the first U.S. building to use domestically-produced Cross-Laminated Timber (CLT); and the Framework project in Portland Oregon, which is slated to become the first high-rise wood structure in the U.S.

7 FEATURED PLENARY PRESENTATIONS

BEN BRUNGRABER Sunday, June 3, 9:00 a.m. - 10:00 a.m. TIMBER FRAME PAVILIONS*

Open Pavilions are among the most compelling timber frames. There is no siding or interior partitions to disrupt the concept—it’s pure architecture, engineering and craft at work.

Not that these wonders are without challenge. They are indeed, and some of them have even performed to the satisfaction of all, and for many years. The two most distinctive aspects of framing open pavilions with timber joinery are limiting sidesway and avoiding exacerbating timber deterioration with deep mortises. Ben will discuss various ways of inducing lateral load capacity in these open pavilions. Doglegs and crucks will be mentioned. Knee bracing may undergo castigation. A few of the myriad ways to develop moment capacity at the post bases will be addressed.

But the heart of the presentation will be copious examples of lovely and unlovely open pavilions. Names may be changed, to protect some of the more innocent. Or not. Lives will be changed. Or not. Given that this entire topic has become a near fixation of Ben’s, you probably ought to bring along your fast hearing aids and sit at least three rows back. This stuff could blow you away. Or not.

JONATHAN ORPIN, GARY ROGOWSKI, & FRIENDS MAKER V. MANAGER: THE PERSONAL CHALLENGE OF FULFILLMENT IN OUR WORK Sunday, June 3, 10:15 a.m. - 11:15 a.m.

From many in our industry, the tension between our roots as craftspeople, creatives and “makers”, and that of managing our coworkers, our projects and our businesses as we grow and mature is a never-ending struggle. The issues of providing a better living for our families, taking on larger and more challenging projects that require increased management, and helping create a “home” and a future for our younger craftspeople can often force us out of the shop, off of the site and into the office. It’s just the way of the world.

This session will tear into this very personal, internal tension, dig into the time we spend “working ON our businesses” versus “working IN our businesses” and act as a sounding board and sharing of tactics, strategies and struggles this creates. We will explore the emotional, artistic and practical chaos of all, as well as real time solutions. In total, this will be more an exploration than a presentation as there is no right answer, no perfect learning to take away. Think about it as a round table discussion, and everyone attending will be welcomed into the conversation.

8 WOOD SCIENCE & ENGINEERING

Micro-Structure and Macro-Behavior of Wood Friday, June 1 Dick Schmidt 11:00 a.m. - 12:30 p.m. Micro-structural characteristics of wood manifest themselves in various wood characteristics, including color, texture, grain pattern and density. These characteristics contribute to a building’s sense of interest and warmth, especially when timber is used as expressed structure. Micro- structural characteristics of wood also influence the workability, durability, strength, stiffness and time-dependent behavior of wood in a structure. The presentation will outline some of the major microscopic and small-scale features of wood and link them to the macroscopic properties of wood as a structural material. Particular emphasis is placed on the response of wood to changes in moisture content and the directional variability in the mechanical properties of wood. The presentation should help designers and builders understand why wood does what it does, so that it can be used properly in a structural application.

Wood Species Identification Friday, June 1 Suzana Radivojevic & Tom Nehil 1:30 p.m. – 2:30 p.m. Learning to identify wood species is an indispensable tool whether you are trying to sort through a stack of mixed species timbers for a new project or trying to evaluate the strength of an existing timber building or bridge. In this presentation, participants will be introduced to scientific methods (don’t let that scare you) used to identify woods so that even unfamiliar species can be identified no matter what the sample size (a board, a log, or a splinter) or condition (planed, rough sawn, or dirty and weathered). Participants will learn basic principles for identifying woods using physical characteristics as well as macroscopic and microscopic anatomical features. Participants will get a tour of: • which physical characteristics can be used as clues to species identification; • basic knowledge of wood anatomy on a macroscopic and a microscopic level necessary for practical wood identification; • what to look for when examining wood in hand, using hand held magnifiers, and using the microscope; • reference materials, including on-line resources, for wood identification; Wood identification requires a combination of practical skills and scientific knowledge and, like any craft, requires practice to master. A “wood identification station” will be provided at the conference where participants will have an opportunity to examine wood samples with magnifiers and with a microscope after the presentation.

Determining Allowable Design Stresses for Timber Friday, June 1 Using ASTM Standards D2555 and D245 2:45 p.m. – 3:45 p.m. Tom Nehil Timber frame engineers are often faced with the task of determining allowable design stresses (reference design values) for timber species not included in the National Design Specification for Wood Construction (NDS©). For many of these species, strength testing has been performed and documented and a standardized procedure exists for establishing allowable properties from the tabulated strength values. American Society for Testing and Materials (ASTM) Standards D2555, Standard Practice for Establishing Clear Wood Strength Values, and D245, Standard Practice for Establishing Structural Grades and Allowable Properties for Visually Graded Lumber, provide the test data and the code-referenced method for determining allowable design stresses. ASTM D245 also provides the means to adjust the reference design values listed in the NDS© for timbers when the grade-limiting defects are less than permitted by grading rules for Select Structural. This can be beneficial when evaluating load capacity of high-quality timbers in new construction and existing structures. This presentation reviews the content of ASTM D2555 and D245 and explains how to interpret them to determine allowable design values. A case history will be presented to illustrate their use. 9 WOOD SCIENCE & ENGINEERING

How to Capitalize on the Hidden Capacity in Timber Friday, June 1 Ron Anthony 4:15 p.m. - 5:15 p.m. Timber structures have performed remarkably well over time. Yet analysis of existing structures often shows that the structure does not have the capacity to support the loads. This is typically due to timber strength that is not accounted for when assigning a structural grade and allowable design values to the timber. This “hidden” capacity is key to structures performing well over time. The means to take advantage of this hidden capacity has not been readily available to practicing engineers, timber framers, and architects. The result of an NCPTT-funded project is an updated grading protocol that will provide the means to make that hidden capacity available to practitioners. The presentation will begin with the science behind the grading rules, leading to an understanding of how the interpretation of the grading rules can impact the performance of structural timber. The presentation will then build on earlier work that resulted in an NCPTT- supported simplified grading protocol. The updated grading protocol incorporates the benefits of (1) smaller defects in much of the timber used in structures and (2) lower in-situ moisture contents compared to new material graded today. Participants will discuss the updated grading protocol to use adjustment factors based on defect size and moisture content to take advantage of the capacity of timber that is unaccounted for in current codes and standards. Upon its release by the National Park Service, the protocol will be available to practitioners for analysis and design of timber structures.

Log Structure Engineering Saturday, June 2 Jennifer Anthony 8:00 a.m. – 9:00 a.m. In this course, Jennifer will discuss engineering design considerations unique to log construction: • Round section properties and differences in computing stresses including full section vs sawn round • TPI (Timber Products Inspection Inc.) log grading values • Design considerations including handcrafted vs milled logs, log taper and average diameter, notched log walls and offset coursing and chinked vs scribed log walls • Shrinkage and settlement • Resisting Lateral loads • Details for roof framing, log floor framing, subfloor framing and foundation connections

Stress Concentrations: The Effect of Notching Timbers Saturday, June 2 Joe Miller 9:15 a.m. – 10:15 a.m. The very essence of timber framing requires taking timbers and cutting away wood in order to form joinery. These reductions in the timber’s cross-section forces any stress in the timbers to be necked down and concentrated in the smaller areas. Depending on how abrupt the changes in cross-section are, the localized stress at these points can be rise dramatically – sometimes well beyond the allowable capacity of the timber. These stresses can either be from applied loads (weight in the structure) or from internal causes (shrinkage). Wood’s mechanical properties also play a large role – as wood is stronger (or weaker) in various directions.

In this presentation, we will look at the basic mechanics of stress concentrations, primarily as it relates to beams and their associated joinery. Our first line of defense against these stress concentrations is mitigating them with better detailing (scooped vs square reductions on joists for example). However, that isn’t always feasible, so we will also spend some time investigating how to calculate and quantify the nature of the stress concentration on the overall effect of the beam’s capacity. Some time will be spent on how to properly reinforce beams near stress concentrations as well (for both new construction as well as on-site repairs).

10 WOOD SCIENCE & ENGINEERING

Fundamentals of Truss, Bent and Wall Design and the Common Deviations that Can Cause Structural Problems Saturday, June 2 Jeff Hershberger 1:00 p.m. - 2:00 p.m. The continued evolution of timber frame design to meet the demands of modern architecture can quickly isolate the weakest elements within heavy timber construction. The progression of open concept floorplans, driven by the widespread availability and acceptance of the manufactured roof truss, marks a design divergence that dismisses conventional spans and load paths traditionally used in timber framing. This modernization along with stricter requirements for structural competence, set forth by the updated residential code and jurisdictional review, often creates reoccurring issues during analysis.

Initial review of the structural properties that define a truss, bent and wall design in this session, will help outline the common structural issues that are created when blending modern design with traditional joinery and timber sizing. Historically these design configurations have remained separate and unique, as builders followed conventional practices passed generationally through the trade. But current design priorities have shifted, thus creating a need for specific elements to be selected from various configurations and combined to form new structures that stray from these traditional designs of the past. Often these morphed designs can be reinforced with steel to achieve the client’s vision, but typically these modifications reduce the likelihood of success with traditional mortise and tenon joinery and are rarely the most cost effective.

The purpose for this talk is to help highlight some reoccurring problems, so they can be spotted and addressed during the early stages of design. Often engineering analysis is the final hurdle needed before project permitting, creating significant issues if structural analysis requires considerable modifications. No timber framer wants to deal with unexpected material costs or to go to a client with a list of required changes to a plan set they believed to be finalized. Therefore, the hope is to give the attendees some additional tools for spotting insufficient concepts in preliminary architectural plans. Allowing for the discussion of project priorities earlier in the design process, where decision making is less clouded with unrealistic structural goals.

Seismic Performance of Knee Brace Timber Frames Saturday, June 2 John P, Judd, Ph.D., S.E. & Fernando Fonesca, Ph.D., S.E. 2:15 p.m. - 3:15 p.m. This presentation presents the final results from a two-year research project sponsored by the Timber Frame Engineering Council (TFEC) and the Timber Framers Guild (TFG). The goal of the research project was to examine the seismic behavior of stand-alone knee-brace timber frames. During the first year of the project, experimental tests of full-scale timber frame knee-braces with mortise and tenon joinery were conducted to investigate hysteretic behavior under combined axial and rotational demands. During the second year, nonlinear finite element models were used to simulate the seismic response of structures using knee-brace timber frames as the seismic force- resisting system. Based on the experimental and analytical results, design values for the response modification factor (R), system overstrength factor (Ω), and deflection amplification factor (Cd) for stand-alone timber frame structures using knee-braces were recommended.

11 SKILLS & CRAFT

Compass and Straightedge: Geometric Layout Friday, June 1 Adam Miller 11:00 a.m. - 12:30 p.m. “I shall now proceed to explain some of the most useful geometrical problems, which every Carpenter ought to be acquainted with.” -Biddle’s Young Carpenter’s Assistant, 1805

Nearly all 19th century carpentry manuals begin with the fundamentals of applied geometry and an overview of the classical orders of architecture. The concurrent rise in manufacture and diffusion of cheap and relatively accurate rules and squares accompanied a general shift from references to classical knowledge toward industrial production. Open a contemporary carpentry text today and you will be discouraged from backing a hip. So, it is a reasonable proposition that our craft would do well to repopularize application of the rich breadth and depth of applied knowledge hard won and perfected over millennia of practice in carpentry and allied trades. A knowledge of applied geometry gives entry to a varied other fields of traditional practice.

In this seminar, we will work through a selection of compass and straightedge drawing exercises. Topics covered will include: • raising perpendiculars given a variety of conditions • producing parallels • dividing angles • developing squares and other polygons

Developing the protractor and graphic approaches to adding and subtracting the areas of squares, rectangles, and circles, as well as a discussion of the development and use of the Scale of Chords may also be included.

Knowledge of the principles underlying the design of innumerable historic and contemporary tools and practices can make any carpenter more confident and efficient.

Faux Finishes: How to Get the Look Your Customers Friday, June 1 Want Without Destroying the Barn 1:30 p.m. – 2:30 p.m. Mike Westgard Faux finish is not just about simulating the look. There is a time and place where faux finish makes sense. Factors like material availability, client vision, restoration reproductions, and time sensitive projects can influence which route you choose. We will explore three main topics; faux finishes, distressing and not so faux finish (hand tools). At the end of this presentation you will have techniques for applying stains and paints to mimic reclaimed colors, distressing with intent, and how power tools can help create the hand-hewn look.

12 SKILLS & CRAFT

The Relationship of Timber and Iron Friday, June 1 Nathan Neale 2:45 p.m. – 3:45 p.m. Structures of timber have been ubiquitous in architecture for thousands of years, and within these creations there has been a direct relationship between timber and iron. Early on, several unique characteristics of these materials were recognized and utilized to form an everlasting bond in the architectural crafts. Perhaps most notable in this relationship was that iron could be transformed into tools for working wood materials. The art of blacksmithing emerged and timber framing gained even greater joinery along with devices such as nails, wedges, brackets, bolts, rods and braces. The craft of timber framing and blacksmithing are ongoing today within their shared amalgamation of traditional techniques, including elements both structural and decorative. An incredible example of these collaborative efforts can be enjoyed by attending this event at the historic Timberline Lodge!

During this presentation we will touch on various topics relating to woods and metals, and enlighten attendees about the art of blacksmithing and how this artistic craft still contributes to timber framing today. There will also be talk of tool evolution, structures made by west coast indigenous culture, various material uses, design possibilities within residential and industrial applications, as well as utilization of materials through reclamation and historic structure preservation. With the advances in technology, it’s more exciting than ever to weave traditional methods and designs that offer limitless build opportunity. Discussion will follow the presentation which will allow for a rich exchange of questions and answers.

What is Sharp and How Do I Get There? Friday, June 1 A Survey of All (OK, well many) Things Sharpening 4:15 p.m. – 5:15 p.m. Darren Watson This session will cover the abstract concept of what a sharp edge really is, some quick basics of steel metallurgy commonly found in our tools in how it relates to hand sharpening, a survey of a number of the common systems used in hand sharpening as well as a few of the popular sharpening machines available today, and a demonstration of a typical Waterstone sharpening set up.

Hand Planes: The Virtue of Slowing Down Saturday, June 2 Gary Rogowski 8:00 a.m. – 9:00 a.m. A hand plane in my shop is more than a symbol of the old days. It is a time saver. The ability to take off a few thousandths of an inch, the difference in a joint between fitting and not fitting is a big deal. The difference between rough and smooth that can make someone appreciate my work is worth a lot to me. It gives me a whole other set of tools in my kit.

Come and learn about hand plane types, hand plane geometry, the importance of a good chip breaker to prevent blade flutter, and the over-all value of the wedge in our work. From large wedges to the small ones I carry with me in my low angle block plane, an understanding of this tool will help to round out your tool kit.

13 SKILLS & CRAFT

Why Timber Frames Stand Up Saturday, June 2 Janet Kane 9:15 a.m. – 10:15 a.m. The Timber Frame Engineering Council is currently sponsoring a research project on the seismic- load behavior of traditional, stand-alone timber frames (those without shear walls or other lateral load carrying components). This presentation will include a discussion of basic considerations for structural design to resist seismic loadings, and it will feature full-scale testing of two sample timber frames that rely solely on pegged knee-braces to resist the cyclic racking deformations representative of a seismic event.

Our intention is to test two full-size bents that will be mounted within a loading frame on a flat-bed trailer. The presentation is intended to be informative to timber-frame carpenters, designers and engineers. Audience members should be interested in this presentation because it represents new information developed from current research regarding the structural behavior of timber frames. Seismic load behavior is not well understood by most timber frame carpenters and designers. Structural engineers understand the fundamental principles, but will be interested in observing behavior of the demonstration specimens and seeing actual hysteresis curves demonstrating the ductility, or lack thereof, of these structures.

A Primer on Making a Scarf Joint Saturday, June 2 Phil Kneisley & Willis Rozycki 1:00 p.m. – 2:00 p.m. Scarf joints were developed because longer timbers were either not available or not practical for the job at hand. This presentation will start with a basic introduction of the joint, and then focus in on one version of the splayed type. In timber-frame historical literature, we read that both Cecil Hewett and Jack Sobon rate the stop-splayed and tabled scarf [with under-squinted butts and wedges] to be a joint among the scarfs which withstands stresses well. We will present a complete shop method to use mill-rule/square-rule lay out, and then cut and fit this joint. Given the constraint of 1 hour, we will prepare ahead of time examples of pieces in various stages of production to aid our presentation and help to prompt questions.

Hewing an Hexagonal Column Saturday, June 2 David Rogers 2:15 p.m. – 3:15 p.m. The purpose of this demonstration is to provide step by step procedures to layout and create a tapered, 6 sided column, similar to the main support columns in the Lodge. The work will be accomplished using tools of the CCC - WPA period.

Starting with a naturally shaped log, we will establish reference lines, use a scoring axe and broad axe to establish the form, use an adze to finish the sides.

Those who would like to participate in the phases of the process are encouraged to do so. I am hopeful that this example will inspire individuals to do more of it in the special features incorporated into the art of structural assemblies.

14 HIGH PERFORMANCE & GREAT DESIGN

Visible Steel in Timber Framing: Case Studies Friday, June 1 Andrea Warchaizer, Chris Koehn, Kevin Mattson, and Friends 11:00 a.m. - 12:30 p.m. Sometimes the wood is meant to be the star of the show and any structural steel is carefully concealed from view. (That’s a talk for another day.) Exposed structural steel, when designed and executed carefully, can be an attractive and welcomed enhancement of a timber framed structure. We’ll look at lots of examples of exposed steel on residential and commercial projects, keeping the technical details to a minimum and focusing on design intent and execution.

Net Zero Energy Friday, June 1 Frank Baker 1:30 p.m. - 2:30 p.m. The building marketplace is changing rapidly. The trend to Net Zero is becoming compelling for many reasons. In this presentation we will attempt to answer key questions about Net Zero: • What are the definitions of Net Zero? • What does a Net Zero home look like? • As builders and designers what should our NZE goals be? • What does the data tell us about the trend in Net Zero Residential building market? • Why is this so important to timber framing businesses? • How can timber framers keep up with the rapidly expanding regulatory environment surrounding Net Zero building? • How can timber framers access the latest NZE technology and market trends.

Building for the Next Generation Friday, June 1 Max Baker 12:45 p.m. - 3:45 p.m. As millennials enter the housing market, they are likely to find themselves in a position that is markedly different from recent generations of homebuyers. In 1970 the median home value was $65,600, in 1990 it rose to $101,100, and in 2017 it was $199,200 (adjusted for inflation). Wages have not kept pace ($53k in 1990 vs. $59k in 2016), debt has increased (the percent of median household income needed to pay for tuition is now 35 percent, compared with 19.5 percent 20 years ago), and the hottest job markets’ have seen steep increases in the costs of living (San Francisco’s one-bedroom rent increased from $1376 per month in 1980 to over $4000 in 2015). These factors have effectively made it harder for aspiring buyers to put money away for a downpayment, delaying their first home purchase or significantly altering their expectations. This has forced many millennials to become creative in order to enter the market; renting rooms out to friends, reducing their desired square footage, and garnering help from family members. However, while millennial homeowners are willing to compromise in many ways, there are certain areas on which they are steadfast; they desire to be close to urban areas and amenities, are willing to pay more for products from socially and environmentally responsible companies (72% of survey respondents in 2015 alone), and don’t want to drive nearly as much (80% say access to public transportation is very important in choosing where to live).

So what does this mean for modern timber framers and homebuilders? How might the industry work to provide for this new generation of aspiring homeowners? As a practicing urban planner, a son of a green homebuilder, a recent homebuyer and an attendee of the Timber Framers Guild since elementary school, Max Baker hopes to provide a unique insight into the wants and needs facing this newest generation of homebuyers. By exploring the intersections of affordability, environmentally-conscious construction and urban planning in the Seattle area, attendees will leave with a greater awareness of the many challenges and opportunities that exist in providing homes for the next generation of homeowners.

15 HIGH PERFORMANCE & GREAT DESIGN

The Dance of Round and Square : Design, Details & Outcomes Friday, June 1 Mira Steinbrecher 4:15p.m. - 5:15 p.m. Learning to weave together the many elements that make up ‘BIG Wood’ structures is important to the many who design, engineer, build or imagine owning such a masterpiece. By gaining a better understanding of basic design & the design process, the attendees will walk away with a plethora of new ideas & possibilities as well as the tools to sort them out.

Attendees will enjoy a number of design examples & ideas while learning more about how the design process works. They will come to know basic design principles in order to expand their understanding of what works & why they like it. Their imaginations will be opened to new possibilities while honing their craft or planning a future home.

Design Software Overview Saturday, June 2 Andrea Warchaizer, Wil Dance & Ruth Koehn 8:00 a.m. – 9:00 a.m. Whether you are producing full sets of architectural plans or just need to draw up a quick plan to sell the job, you’ll need to make a decision about what software will best suit your needs. Will you draw 2D plans or model the building in three dimensions? Simple CAD or BIM (Building Information Modeling)? Entry-level pricing or higher-priced option? We’ll give an overview of what’s out there, what people are currently using, and the particulars that distinguish each software choice. We’ll talk about SketchUp, AutoCAD, Revit, and Dietrich’s, and show you a little of each along the way.

Vapor Permeable and Carbon Friendly Saturday, June 2 Wall Envelopes for Timber Framed Buildings 1:00 p.m. – 2:00 p.m. Joseph Becker Joseph Becker will discuss vapor permeable wall systems that can be used for wrapping timber- framed structures. This family of materials includes cement coated waste wood, lime coated hemp and clay coated straw. Some of these materials are old world, are having a worldwide and modernized resurgence and have been used for in buildings for close to 1000 years that are still occupied. Others are more modern responses and adaptations to our changing world and a shared goal of building better through creating healthy shelters, people friendly building processes, and ecological culture and communities.

When looking at durability, health, comfort, fire, pest proofing and sustainability, these systems have the potential to meet, out-perform and challenge some of the conventional building systems on a broad context. Costs and energy performance can be comparable to conventional energy efficient building envelopes depending on time horizons, how appropriate the design is, access to skilled project managers, as well as how and by whom the work gets done. Increasing numbers of designers, contractors and owner/builders are engaging with these methods and materials as they have the potential to weave together great building science, energy efficiency, resource/carbon conservation/sequestration and least toxic materials.

Advanced, High Performance and Low-Carbon Materials Saturday, June 2 Bruce King & Friends 2:15 p.m. – 3:15 p.m. What do recycled pallets, small diameter trees, marijuana stems, straw bales and mushrooms have in common? All are being used, along with timber framing, as part of the growing movement to make the built environment into a global carbon sink. Bruce King leads an eclectic panel of material experts to discuss alternatives that will play a part in lowering the carbon footprint of all buildings. 16 LIFE, THE UNIVERSE & EVERYTHING ELSE

Historic Timber Structures Friday, June 1 David Rogers 11:00 a.m. - 12:30 p.m. The Tree. One of the Creator’s gifts to mankind. Roundish in profile, tapering in form, shaped into function, the tree provides us with many of our needs.

This presentation will revisit our ancestors’ use of the tree in the construction of structural frames. We will observe some of the various ways people have joined and married logs together.

The Scandinavian / European immigrants to North America brought with them their unique ways of working with trees to construct shelters and other necessities. Round logs were hewn to flatted forms and joined in familiar ways. Or, they were kept in their natural form and joined in familiar ways.

The French trappers of the Hudson’s Bay Company are credited with a ‘piece-en-piece’ style as they made their way across the continent towards the west.

The occupants of the land they encountered along the way had developed their own styles of shelters utilizing the various materials at hand.

The Pacific Northwest Indian Nations had the gift of the cedar tree. They had developed forms of architecture that, in 1792, inspired the French explorer Etienne Marchand to write, “Is not our astonishment increased when we consider the progress these people have made in architecture? What instinct, or rather, what genius, it has required to conceive and execute solidly . . . those heavy frames of buildings of fifty feet in extent by eleven in elevation?”

Early North American explorers and settlers incorporated architectural styles of the indigenous people they encountered.

In the 1930’s - 1940’s, the Works Progress Administration / Civilian Conservation Corps marched across the nation putting the youth to work constructing, repairing, rebuilding and replanting the damaged landscape. Timberline Lodge is one of many forms of native material utilization that represents the essence of human ingenuity throughout our occupancy on this earth.

The area around Mt. Hood is dotted with CCC era structures. Many of these will be highlighted during this presentation. We will also delve into the aspects of ‘historic preservation’ vital to retaining these structures for the generations yet to come.

The Sawmill Friday, June 1 Bob Sproul 1:30 p.m. - 2:30 p.m. I was owner operator of East Fork Lumber Company for awhile, almost 35 years until I recently retired, turning the sawmill over to the next generation. Our company grew as the timber frame industry did. We also went through some tough times as did many timber framers.

Over the years one of the constant challenges was the procurement of logs to produce the products required by our customers. East Fork Lumber bought logs throughout Southwestern Oregon and Northern California. We we were impacted by the timber wars, the spotted owl, Clinton’s Northwest Forest Plan, and pension plans. With over 70% our forests belonging to federal government, the activities on these lands has a direct impact on our families.

17 LIFE, THE UNIVERSE & EVERYTHING ELSE Behind every timber is a stump. I like to think that for almost every timber sawn I could show the stump it came from. We could discuss the why’s and what’s of why it was cut down. Then we could discuss the products we could make from that tree. Currently the challenges are many. The times are changing, they always have been and always will. Two of biggest challenges I see are the changes in use of and type of wood products and the fires decimating our forests.

The future always holds untold possibilities. Building of shelters that make us feel comfortable, and that grow more beautiful over the years has been a goal I believe achieved by many members of the TFG and I feel honored to have been part of it.

ATP Presents: Holy Grail of Roof Framing Geometry & Trigonometry Friday, June 1 Sim Ayers 2:45p.m. - 3:45 p.m. Sim will discussing his new book, Holy Grail of Roof Framing Geometry & Trigonometry: Book I – Trigonometry Book II – Roof Framing Book III – Geometry Book IV – Everything Circular

These books are for anyone interested in learning the geometric process to roof framing as well as the trigonometric formulas that have evolved from the geometry. A lot of the geometry in the books will be the first time there’s an English explanation to the geometric drawings.

Precise rafter layout can only be accomplished with a knowledge of the geometry that develops the parallelogram in the compound joint. Take away the carpenters framing square, CMC calculator, and circular saw to show you what they really know about cutting rafters. Can they still layout and cut a hip rafter without the use of these tools? These books will help you acquire the knowledge that has been pasted down by the builders of the past.

Building Community: Volunteer Projects, Social Justice, and Meaning Friday, June 1 Steve Eisenbach-Budner 4:15 p.m. - 5:15 p.m. Have you yearned to use your construction expertise in the service of your highest ideals for our society? Have you engaged in a volunteer project that you knew had greater potential? Join Steve Eisenbach-Budner, founding Executive Director of Tivnu: Building Justice and former Construction Trainer at Portland Youth Builders as he reflects on two of his projects with Tivnu – working with Hazelnut Grove, a village of formerly houseless individuals, and helping to build the Capaces Leadership Institute, which trains the leaders of the farmworkers and immigrants’ rights movement and is the first certified Passivehaus office building in the United States. Steve will discuss the profound outcomes that can be achieved when builders use their skills to facilitate construction projects that raise the voices of our communities’ most marginalized members, connect folks whose paths wouldn’t otherwise cross, provide a forum for discussion of the broader issues beneath the project, and help real people in real time.

18 LIFE, THE UNIVERSE & EVERYTHING ELSE

Why Trees Are Stonger than Wood Saturday, June 2 Roald Gunderson 8:00 a.m. – 9:00 a.m. Architect and whole tree builder, Roald Gundersen has spent the last 25 years designing and building with trees. He prunes and bends trees as part of his forestry and uses their branching and curved shapes to create uniquely beautiful, renewable and durable structures. Roald will share a few of his adventures with trees and buildings from his forestead near La Crosse, WI to his work with the Forest Products Labs, a big-box grocery, and a new band shell project.

The Moosilauke Lodge Saturday, June 2 Adam Miller 9:15 a.m. – 10:15 a.m. Creating the round-log timber frame for the Moosilauke Ravine Lodge challenged the skills, endurance, and spatial thinking strength of our group of craftsmen for over a year-and-a-half. This slide presentation will follow our work from cruising standing timber to project completion, expanding upon the article featured in Timber Framing 126. Along the way, we create an efficient system for horizontal bubble-scribing and debate the details of purpose-designed joinery, juggling 50 ft. logs and 7000 lb. trusses into massive upside-down assemblies, all in preparation for demanding a winter raising on a mountain in northern New Hampshire.

ATP Lunch & Learn Join the Apprentice Training Committee for an informal discussion on the re-launch of the Guild’s Department of Labor registered program. The Committee wants to hear your thoughts and suggestions on the future of the ATP. Grab a quick lunch in the Wy’East Hall and meet in the Barlow Room, Saturday at noon.

19 LIFE, THE UNIVERSE & EVERYTHING ELSE

Timber Framing in Remote Locations Saturday, June 2 Dave Petrina 1:00 p.m. – 2:00 p.m. Kettle River has built over one dozen timber frames and full homes on remote locations along BC’s rugged west coast, all of which were boat access only. These off-grid locations typically present a myriad of challenges seldom encountered on a standard project. Using photographs, examples and stories from his own experience David Petrina, owner and founder of Kettle River Timberworks, will share his hard won knowledge.

One of the unique challenges is transportation. He will offer insights into the implications of using barges, ferries, trucks and even helicopters for getting material to the site and the impact of site conditions on transportation options.

As a designer of both timber frames and full homes, Dave will also illuminate the critical role that house and frame design play in a successful remote build and specifically the impact of design on transportation and ‘remote raise-ability’. He will also delve into considerations for heating, plumbing, water collection and security when designing for remote locations.

Building off-grid means coming up with new solutions for off-site constructions. Various portable crane options will be reviewed as well as utilizing solar, generators, and battery-powered tools.

Remote construction presents unique labor force challenges. Dave will identify some of those challenges such as crew schedule, safety, accommodation, travel, meals and moral, sharing what he’s found is pivotal to a successful execution as well as some of the possible pitfalls.

The ‘unknown’ takes on a whole different significance in a remote build and proper planning for the unexpected can make or break the project. Dave will highlight potential hazards such as weather issues, breakdowns of tools, equipment and crew, missing tools and/or materials and how to mitigate them.

Naturally, all of the above have an impact on budget and Dave will incorporate ideas on what to consider when budgeting, costing, structuring contracts and billing for remote locations builds.

This presentation will be of particular interest to builders and timber framers but also designers and architects. Attendees will come away with a good understanding of the additional challenges associated with remote construction and some best practices to ensure a safe and effective build.

Timberline & WPA Saturday, June 2 Sarah Munro 2:15 p.m. – 3:15 p.m. The construction of Timberline Lodge as a Works Progress Administration project was unlikely to succeed for many reasons but today the building is an American icon for the WPA. Challenges included funding, design, location, materials, timing, and manpower. Sarah will focus on the development of the idea for a lodge at the timberline through its construction, furnishing, and early operation, including initial proposals, funding sources, designs for the building and its utilities, materials of wood and stone, and challenges created by the alpine environment. She will also discuss the art and craft projects and early operators.

Ben Brungraber got started in timber framing by reinforcing and repairing Pennsylvania covered bridges during college. He got a Master’s at Colorado State University, studying timber structures and headed for that hotbed of log building design – the Empire State Building. He taught at Bucknell for two years, helping students to stabilize an ancient covered bridge and to build a new fifty-foot pedestrian version that carries traffic to this day. His Stanford PhD dealt with pegged mortise and tenon joinery. Two years of teaching at UConn was enough to convince him to spend the next two decades as a lead engineer at Benson Woodworking. As the economy tanked, he and Mack Magee launched Fire Tower Engineered Timber, but have been blessed with two fine partners since. Ben has served as a Guild Board Member and as an early beleaguered Treasurer. He is thrilled to be speaking here; in the second best building on the planet - following only the iconic Empire State Building.

Bob Sproul: I started East Fork Lumber in 1983 after spending 10 years as a carpenter/contractor. I had decided I had fallen in love with wood and wanted to spend more time with it. My wife, Anne thought that I might not be thinking straight, but she didn’t divorce me and I bought my first sawmill, for $8,000. Little did I know that it would cost over $100,000 to manage the waste products.

I am fortunate to live in Southwestern Oregon where forests grow with abundance. I was also fortunate enough to meet some timber framers who were looking for some good wood. The next 35 years were spent searching for good wood, making timbers and running a chainsaw. We grew as the members of the Timber Framers Guild grew and we faced many challenges from changing building methods and changing markets. But it was enjoyment of seeing well grown trees turned into a properly cut timber placed in well designed structure that made it worthwhile.

David Rogers: I have been involved in log related work for more than 40 years, starting in 1972 in the forests of Northern California, setting chokers for the logging industry.

In 1983, I graduated from the B. Allan Mackie School of Log Building and Environmental Centre. (A Trade School near Prince George, British Columbia). At that time, ‘new’ logwork was very similar to the ‘old’ logwork.

In the early ‘90’s, John Platz, an engineer working out of the Zig Zag District, put together a US Forest Service team to maintain the existing CCC structures in the Mt. Hood Forest. He also envisioned constructing new ‘Heritage’ structures as a way to preserve the traditional construction means and methods of the Works Projects Administration (WPA) and Civilian Conservation Corps (CCC) architectural style so abundant in our region. I was hired by John to teach the team the use of traditional hand tools during the course of several years. It was John who first introduced me to the Study of historic preservation.

Since then, I have worked as a Contractor on many Log and Heavy Timber structures dating from the 1850’s to the 1940’s and, on occasion, construct new log homes. The value and pleasure of repairing and rehabilitating old buildings has become more important as the years go by.

Frank Baker: Trained as a mechanical engineer, I initially worked in the automotive industry. My love of timber framing started with my grandfather’s timber frame home that he built in the late 1940’s on the banks of the Maumee River in Ohio with recycled industrial timbers.

When we started building our first home, there was so much regional interest in what we were doing and so few resources in the Midwest, that even though mortgage interest rates were at the highest ever and the awareness of timber framing was incredibly low, it somehow seemed to be a good time to start a timber frame company. Riverbend Timber Framing began cutting frames 1979 in our barn before eventually moving to a facility that would allow the entire timber to fit within the indoor space. Insulspan SIPs came along in 1990.
