Austin NARI 15Th Annual Tour of Remodeled Homes
Austin NARI 15th Annual Tour of Remodeled Homes Saturday & Sunday April 7-8, 10-6p Scan on page 3 for full access to the NARI Tour of Remodeled Homes 2018. Letter From The President WELCOME TO THE 15TH ANNUAL AUSTIN NARI TOUR OF REMODELED HOMES 2018! Starting as far back as 2003 when ABC first introduced Extreme Makeover: Home Edition with the lovable Ty Pennington, consumers have been drawn to the dramatic transformations portrayed on television with radical before and after images. From Drew & Scott of the Property Brothers to Chip & Joanna of Fixer Upper, there’s no doubt America loves to see a beautiful home transformation unfold in a matter of days/weeks on an affordable budget. The problem with reality TV shows, however, is there is nothing realistic about what they portray; from unrealistic budgets including donated products and labor being traded for on-air advertisements, to deadlines achieved by multiple trades working on top of each other to finish a job sacrificing quality over appearance. Step inside one of the twelve newly remodeled homes on this year’s Austin NARI Tour of Remodeled Homes executed by nine of the area’s top remodelers to see what the remodeling WE’VE GOT GREAT GLASS! market is really about. From kitchens and baths to outdoor remodels and whole home transformations there is a little of everything to spark your interest and help you draw up ideas for your next remodeling project. Ask us the hard questions about timelines, budgets, and feasibility and you will understand why we are passionate about the remodeling industry and setting up realistic expectations for successful projects. -
Investment Casting Or the Lost Wax Process
Investment Casting or The Lost Wax Process Apecs Investment Castings was founded in 1963 and is now situated in the Melbourne suburb of Burwood where we have been since we outgrew our Canterbury factory in August 1987. The company name (APECS), stands for Anthony Philip Eccles Casting Service. Investment is a type of plaster that we use in our process of reproducing multiple copies of an original master pattern which is usually supplied to us by our customers. This is a classic 18ct yellow gold emerald and diamond ring taken from the Apecs catalogue. The next series of photos will show the steps involved in producing multiple copies of this ring. An original master pattern is designed and fabricated by our customers and supplied to us to reproduce in the quantities and metals of their choice. It is important to ensure that the master is made as accurately as possible and to pay particular attention to the finish of the master pattern. The better the quality of the master pattern the better the casting result. The finished master pattern ready for the caster. A picture of the master pattern is drawn and a mould number is allocated for identification. When the customer wants to reorder he quotes the mould number for the pattern he wants. A sprue is soldered onto the pattern. This sprue enables the pattern to be easily located in the mould and will provide the path for the wax to be injected into the rubber mould. To make a mould the master pattern is placed between sheets of uncured vulcanising rubber. -
Bifilm Inclusions in High Alloyed Cast Iron
materials Article Bifilm Inclusions in High Alloyed Cast Iron Marcin Stawarz * and Malwina Dojka Department of Foundry Engineering, Silesian University of Technology, 7 Towarowa Street, 44-100 Gliwice, Poland; [email protected] * Correspondence: [email protected]; Tel.: +48-32-338-5532 Abstract: Continuous improvement in the quality of castings is especially important since a cast without defects is a more competitive product due to its longer lifecycle and cheaper operation. Producing quality castings requires comprehensive knowledge of their production, crystallization process, and chemical composition. The crystallization of alloyed ductile iron (without the addition of magnesium) with oxide bifilm inclusions is discussed. These inclusions reduce the quality of the castings, but they are a catalyst for the growth of spheroidal graphite that crystallizes in their vicinity. The research was carried out for cast iron with a highly hyper-eutectic composition. Scanning electron microscopy and EDS analysis were used in the research. A detailed analysis of the chemical composition was also carried out based on the spectrometric method, weight method, etc. Based on the obtained results, a model of spheroidal graphite crystallization near bifilm inclusions was proposed. The surface of the analyzed graphite particles was smooth, which suggests a primary crystallization process. The phenomenon of simple graphite and bifilm segregation towards the heat center of the castings was also documented.

The Lost-Wax Casting Process—Down to Basics by Eddie Bell, Founder, Santa Fe Symposium
The Lost-Wax Casting Process—Down To Basics By Eddie Bell, Founder, Santa Fe Symposium. Lost-wax casting is a ancient technique that is used today in essentially the same manner as it was first used more than 5,000 years ago. As they say, there's no messing with success. Today, of course, technology has vastly expanded the technique and produced powerful equipment that makes the process faster, easier and more productive than ever, but the basic steps remain the same. The steps below represent a simple overview and are intended to provide a beginning understanding of the casting process. Concept This is obviously where the design is initally conceived, discussed,evolved, and captured on paper—or on computer; CAD (computer aided design) software is increasingly popular among designers. You create the design you envision using the computer tool and the software creates a file that can be uploaded into a CNC mill or 3D printer. Model Build a model, either by hand-carving, guided by the paper rendering, or by uploading the CAD file into a computer controlled milling machine or a 3D printing machine. Models are made using carving wax, resin or similar material. This process can also be done in metal by a goldsmith or silversmith. Note: If a 3D printer or other rapid prototyping equipment is used, it is possible to skip the molding and wax-injection steps by using one of the resins that are specially made to go directly to the treeing process. Molding Create a mold from your master model, placing it in one of a variety of rubber or silicone materials, curing the material, then removing the model from the finished mold. -
Chapter 2.6-Porches and Balconies
HISTORIC RESOURCE DESIGN GUIDELINES CHAPTER 2.6: PORCHES AND BALCONIES CITY OF SANTA BARBARA CHApteR 2.6: PORches AND BALconies INTRODUCTION Historic porch and balcony design, scale, and detail vary with the architectural style of the building. Victorian porches were often ex- tensively detailed, extending the entire length of the building and supported by large columns. In contrast, other styles such as Span- ish Colonial and English Revival may not have a porch, but rather an overhang over the front door. Many Mediterranean or Monterey Revival historic resources also do not have porches, but have front façade balconies as one of the main featured elements. Historically, residential porches, stoops, porticos, terraces, entrance courtyards, porte cocheres, patios, and verandas provided sheltered outdoor liv- ing space in the days before reliable climate control. They defined a semi-public area to mediate between the public street areas and the private area within the home. They also provided an architectural focus to help define entry ways and allow for the development of architectural detail. Typically, areas covered by a porch, including windows, doors, and wall surfaces, tend to require less maintenance than other more exposed areas of the house. The shade provided by porches can reduce energy bills. However, steps, railings, and roofs are usually exposed to the weather and may require additional main- Porches are a common feature of many turn-of-the-century houses in Santa Barbara, including these in the West Downtown Neighborhood. tenance. Porch design, scale, and detail vary widely between architec- tural styles. To determine what elements are particularly important on your porch, consult the architectural styles appendix of these Guidelines or contact the Architectural Historian for a consultation. -
Producing Pattern, Corebox Or Model Components Using Metalworking Machines
SEMPAT13 Producing pattern, corebox or model components using metalworking machines Overview This unit identifies the competencies you need to produce pattern, corebox or model components using machine tools, in accordance with approved procedures. You will be required to select the appropriate equipment to use, based on the type of operations to be performed, the size of the components and the materials to be used. The production of the components will involve the use of both fixed and portable conventional machines, which are designed specifically for metallic materials. The size and complexity of the components produced will vary, and this will require you to set up the necessary machines and their associated tooling, and to make any necessary adjustments during machining in order that the parts produced meet the required specification. The components produced will be used to produce loose or plated patterns (with and without cores), coreboxes, and various types of full and scale models. Your responsibilities will require you to comply with organisational policy and procedures for the machining activities undertaken, and to report any problems with the activities, materials or equipment that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with minimum supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out. Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying metalwork machining procedures. You will understand the equipment being used, and its application, and will know about the tooling, machine setting arrangements and safety devices, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring the work output is to the required specification. -
St Luke's Farnworth BELL CASTING
St Luke’s Farnworth BELL CASTING by Geoffrey Poole In the earliest days they were cast in different sizes to produce different notes but no attempt was made to tune bells until the 16th Century with the advent of change ringing. In those times bells were roughly tuned – where the inside of the bell or the edge of the lip was chipped away with a hammer and chisel – eight bells could be tuned to an octave of eight notes. Some deprived communities used a hagiosideron, a shaped piece of metal which was struck in a similar way to a bell. Also again due to lack of money bellcotes were used instead of costly towers. A bell-cot, bell-cote or bellcote is a small framework and shelter for one or more bells. Bellcotes are most common in church architecture but are also seen on institutions such as schools. The bellcote may be carried on brackets projecting from a wall or built on the roof of chapels or churches that have no towers. The bellcote often holds the Sanctus bell that is rung at the consecration of the Eucharist. Bellcote is a compound noun of the words bell and cot or cote. Bell is self-explanatory. The word cot or cote is Old English, from the Germanic. It means a shelter of some kind, especially for birds or animals (see dovecote), a shed, or stall. Examples of bellcotes In order St Luke’s Farnworth Bell-cot at St Edmund's Church, Church Road, Wootton, Isle of Wight, England Church of England parish church of St Alban the Martyr, CharlesStreet, Oxford.
