If the subfloor needs SLIGHT adjustment, you can alter the 2" dimensions slightly to make chalk lines square. This measurement allows the logs to overhang the foundation so that siding covering the perimeter sill will match correctly. (The ¾” T&G subfloor should be flush with the outermost edge of the perimeter sill.) Figure 4-2 Layout Using Chalk Line 3. Position Logs : First, measure and mark the base logs to reflect the centerline of the log wall. Measuring from the exterior crown (top) of the base log, put a pencil mark at 3¾” and extend it down to the bottom of the log using a carpenter’s square (Figure 4-3). Then, beginning at the front door, lay the base logs over the chalk line, aligned with the centerline mark. Move clockwise around the building perimeter, from left to right following the numbering on the log assembly overlays. Be sure locations of all door and fireplace openings are according to final plans. (It is possible to accidentally reverse a wall.) At door openings, use the top, or header portion of the door buck, as a spacer to insure correct spacing for base logs. Check the length of buck headers to be sure they are cut to the exact width of the door opening. (See Section 4.2 on page 4-8 after the First Course: “Install Door Bucks”). 4-4 © 2019 DIY Log Cabins, LLC DIY Log Cabins Construction Manual 4. Check Straightness : Stretch a string line between nails driven into the tops of the logs at either end of the wall (Fig.4-4). Use the string as a guide to assure that the log course is perfectly straight. If the logs have been positioned correctly and the subfloor is accurate, the base course should overhang the edge of the subfloor as shown in Fig. 4- 3. 5. Apply Sealant : Once you have verified that the base log course is accurately placed, move the base logs aside and apply construction adhesive between the subfloor and base log course to create a weather tight joint (Fig. 4-5). Apply 2 continuous beads at approximately 1” and 3” from the edge of the subfloor on both sides of the chalk line. Check for square and straightness, then set base logs back into their final position. Figure 4-3 Setting the Base Course Figure 4-4 Checking Straightness with a String Line 6. Toenail Joints : Toenail the logs together with 2-16d galvanized nails to tighten each butt joint and corner, being careful to avoid any log movement (Detail L-6, Pg. 4-36). The log overhang should be uniform all around the perimeter (see Fig. 4-3). Figure 4-5 Applying Sealant © 2019 DIY Log Cabins, LLC 4-5 4 Stockade Assembly 7. Install LogHog™ Fasteners : With the base logs sealed and in proper IMPORTANT! location, install LogHog™ fasteners in the base course and countersink heads Base log LogHog™ (screw down until tops of fastener heads are slightly below log surface) using fasteners should socket provided. Typical placement specifies 2 fasteners at each butt joint penetrate into triple and corner (Figures 4-5 & 4-7). This means that logs 24” or less in length 2x10 perimeter sill. should have at least four fasteners. Additional LogHog™ fasteners are In the unlikely event positioned every 36" on center and staggered, or altered from inside to that a log should outside of log (Figure 4-5). For logs over 24” but less than 72” in length, 2 need to be removed, fasteners staggered in the center third of the log are recommended (minimum (maybe the wrong of six fasteners). (Detail L-5, Pg. 4-33) log was fastened in by accident), the LogHog™ fasteners can be removed by reversing your drill and removing them. Figure 4-5 Setting LogHog Fasteners in Base Course When fastening the logs, alternate sides of the log when installing the fasteners. Fastening completely down one side first will tighten that side but may create a gap on the other side that does not pull completely together. This results in a log that is not seated flat. Left uncorrected, successive courses of log will tend to roll, and it will be difficult to bring the wall back plumb. When detected early, shims or washers may be used to lift one side of a single course to correct roll, but this is not recommended as a common practice. 8. Install Dowel Pins : After all LogHog™ fasteners have been installed and tightened, drill 1” holes approximately 6" deep (stack height of one log) at each butt joint (Figure 4-4) using a 1” wood drill bit (NOT SUPPLIED). Figure 4-4 Drilling at Butt Clean away sawdust, fill 1/4 to 1/3 with caulk, and hand press dowel pins Joint for Dowel Pin into each hole so that the top of the dowel is slightly lower than the top of the logs (Detail L-6, Pg. 4-34). 4-6 © 2019 DIY Log Cabins, LLC DIY Log Cabins Construction Manual 9.

  • Folk Log Structures in Pennsylvania
    Folk Log Structures in Pennsylvania By Thomas M. Brandon Research Assistants: Jonathan P. Brandon and Mario Perona FOLK ARCHITECTURE The term ‘folk architecture’ is often used to draw a distinction between popular or landmark architecture and is nearly synonymous with the terms ‘vernacular architecture’ and ‘traditional architecture.’ Therefore, folk architecture includes those dwellings, places of worship, barns, and other structures that are designed and built without the assistance of formally schooled and professionally trained architects. Folk architecture differs from popular architecture in several ways. For example, folk architecture tends to be utilitarian and conservative, reflecting the specific needs, economics, customs, and beliefs of a particular community. (Source: Oklahoma History Society’s Encyclopedia of Oklahoma History and Culture, Website. http://digital.library.okstate.edu/encyclopedia/entries/F/FO002.html, Alyson L. Greiner, February, 17, 2011). Note. Much of the data and pictures found in this field guide came from a study on log structures in 18 counties of western and central Pennsylvania. The Historic Value of Folk Log Structures The study of folk log construction, also known as horizontal log construction, is exciting because, unlike most artifacts from the pioneer era, log structures have not been moved from where the pioneers used them. The log structure remains intact within the landscape the pioneer who built it intended. Besides the structure itself, which provides valuable information about the specific people who occupied it, the surrounding historic landscape tells it own story of how the family lived, from location of water sources and family dump to the layout of fields, location with other houses in the neighborhood and artifacts found in the ground still in context with their original use.

But they had to find very long pieces of wood, so people started making small squares and building them up to the right shape, then joining the squares diagonally to make a roof. By now, everyone was squaring their timber, because a) it's more uniform, and removes uncertaintly; b) all joints can be almost identical – you don't have to take into consideration the shape of the tree; unskilled people can then be employed to make standard joints; and c) right- angles fit better, joints become stronger, and you can fit bricks / wattle & daub in more easily.

  • Dovetails and Broadaxes: Hands-On Log Cabin Preservation
    Dovetails and Broadaxes: Hands-On Log Cabin Preservation Appendix E—Log Building Origins and Styles Plan and Form As they moved westward, European-American settlers suc- cessfully adapted log construction techniques to regional materials, climates, and terrains (figures E1 and E2). The floor plan and shape of log buildings constructed in the 1700s and early 1800s sometimes can provide clues to the eth- nic origin or route of migration of the original inhabitant or builder. Because the settlers often borrowed and copied tech- niques used successfully by their neighbors, don’t infer too much about the ethnic origins of a cabin’s builders from the way they constructed the cabin. Figure E2—The builder of this cabin at the mouth of Big Timber Creek Canyon on the Big Timber Ranger District in Montana (Gallatin National Forest, Northern Region) used a stone foundation with massive, battered stone corners and porch piers, and moderate diameter, round, softwood log walls. The cabin has a steep cedar shingled roof and a rock chimney for a wood stove near the center of the building. The entry is on the gable end under a gabled porch. It was sold and removed from the site in the early 1980s. The basic unit of each of these types is the one-room enclo- sure formed by four log walls joined at their corners, called a single pen or crib (figure E3). People sometimes divided the single pen by interior partitions or enlarged them by add- ing another log pen.

A Nebraska Log Cabin by Marvin Liewer [ 2004 ] Preface Nebraska pioneers built their homes with materials that were locally available. The prairie often dictated the use of sod. However, logs were generally used when trees were available. Today, logs are used in construction of country homes, vacation cabins, and hunting lodges despite modern construction materials. Log construction is aesthetically pleasing and energy efficient. In 1994, I began building a log cabin along the Niobrara River near Butte, Nebraska. My goal was to build an attractive, comfortable cabin using local wood products. I used ponderosa pine logs for the walls. Bur oak and green ash lumber was used for window and door trim. Stair and porch railings were constructed from hand-peeled eastern redcedar poles. Redcedar boards were also used for paneling the basement. The purpose of this report is to describe local wood products and specific constructions tech- niques used in my successful log cabin project.

  • Program Description PD-1 CAMP TAHQUITZ PROGRAM
    Camp Tahquitz Summer 2021 Program Description PD-1 CAMP TAHQUITZ PROGRAM THE ADVENTURE STARTS HERE PROGRAM PLANNING HINTS The highlight of any scout's year is the week he spends at summer camp, and the highlights of a Scoutmaster's year is the time that he spends with his scouts in the cool, clean air of Camp Tahquitz. To make sure this happens you should start with good program planning. Here are a few ideas and hints on how to easily plan an exciting, rewarding, and enjoyable week at Tahquitz. BOY PLANNED Planning the troop's summer camp program can be part of the growth process of Scouting if the Scouts themselves are involved through their Patrol Leader’s Council. The PLC, with guidance from the Scoutmaster, should see that the troop program reflects the individual goals of troop members as well as the collective aims of the. Greater scout involvement in planning will assure greater scout enjoyment in participation. BALANCED Experience has shown that the best program at camp is one that offers each scout a healthy balance between recreation and advancement, free time and structured activity, group events and individual pursuits. We recommend that scouts do not undertake more than three merit badges during their stay at camp and that each scout is allowed enough free time to enjoy his surroundings, pursue his interests, and to build friendships. INDIVIDUALIZED A successful camp program reflects the different ages, ranks, and skill levels of the troop. While it is good for the troop to conduct some activities as a whole, other programs should be geared to the personal needs and goals of the troop members.
