Pre-Conference: When Roofs Collide! $175

Time 9am - 5pm Thursday, August 1

This workshop combines basic and advanced, traditional and modern methods for solving complex roof problems.

The first half-day will cover the basic techniques for figuring the angles and lengths of rafters in regular hip and valley roof systems. Intersecting roofs in such a system have equal pitches and rest on walls that meet at 90-degree corners. Participants will learn to locate and layout the peak, bird’s mouth and backing angle cuts for hip and jack rafters. Methods used will include the rafter square tables, geometry and calculators, visualization with traditional drawing, and the Hawkindale angles spreadsheet. While computers can now be used to solve these problems, it is best to learn the various traditional methods first to better understand how roofs come together and what the important information is for input to the computer.

The second half-day will introducing the concept of the “tangent” and its use to solve an irregular roof problem. In this case the roofs will have different pitches and the supporting walls will meet at angles other than 90 degrees, and tools like the rafter square tables can no longer be used. Participants will focus mainly on scale drawing to figure the angles of the top and seat cuts of jack and hip rafters, backing angles and hip offset.

Pre-built scale models will be used to help participants visualize the roofs and to check drawings done in the class. Bring basic drawing tools such as a compass, colored pencils, protractor, and rafter square (framing square with rafter tables) and a calculator (Construction Master or scientific).

Will Beemer is the Director of the Heartwood School in Washington, Massachusetts and has been teaching timber framing and roof geometry for 40 years. He is the author of the five-part series of articles titled "When Roofs Collide" that appeared in issue numbers 70, 71, 73, 90, and 92 of the Guild’s quarterly journal Timber Framing, which is recommended reading for these workshops. His book, Learn to Timber Frame (Storey Publishing) came out in 2016.

Pre-Conference: Walking Tour of Historic Manchester $35

Time: 9:30am - 3pm, Thursday, August 1

Thursday's basement to steeple tour will feature historic structures and churches in the downtown Manchester area.  This will be a walking tour of local landmarks and we will see extraordinary trusses and roof framing.   We will begin at 9:30 at the SNHU campus and travel by regular bus service to the downtown center.  From there we will split the groups up and cycle through the church steeples and buildings allowing plenty of time for viewing and discussion.  Lunch is on your own downtown. There are ample eateries for every taste.  The tour will wrap up around 3 pm with local buses heading back to campus.

Pre-Conference: Timber Frame Engineering Symposium $375

Time: 8 am-6:30 pm, Thursday, August 1

The Timber Frame Engineering Council (TFEC) will  host its annual symposium, scheduled immediately prior to the national conference in Manchester, NH on Thursday, August 1.  Our symposia are known for offering in-depth reviews and open discussions on the state-of-the-art in the engineering of traditional timber framing.

Pre-Conference: Sketch Up Users Group $175

Time 1pm-5pm Thursday, August 1

We are still in the process of putting together a half-day-long session for SketchUp users. The day will include specific skills training for SketchUp Pro and Layout in the production of timber frame and architectural plans. We'll have time to share tips and tricks and field questions as well. This workshop is intended for advanced beginner through experienced SketchUp users; participants should have at the minimum a basic working knowledge of the program and be ready for a fast-paced day. Lunch included.
