Pre-Conference Event: Wood Species Identification Workshop (Level 2)

Join the Guild at the University of Wisconsin-Madison Botany Department for this intensive one-day workshop on Wednesday, May 17. Participants will learn to identify woods by studying both macroscopic and microscopic anatomical features. This workshop is suitable for those with at least entry-level familiarity with wood anatomy and species identification and will build on skills learned in the Level 1 Wood Species Identification Workshop.

Pre-Conference Workshop: Complex German Roof Framing

This two-day workshop (May 18 & 19), led by Gerald David of GFD Wood Working, will focus on the hip roof development of the German school of timber framing. Through the course of this special event, we will:

  • Build the roof portion of a 10’ by 16’ structure. The longer main eave has a 14/12 pitch; the shorter eave has a 20/12 pitch. 
  • Cut and erect the plates and ridge assembly, followed by this hips, common, and jack rafters.
  • Cut and join the plates and ridge assembly using traditional corner joints, mortise and tenon joints, and half lap joinery. 

The compound cutlines for this exercise with two different roof pitches will be derived geometrically using traditional methods. We will use a layout floor for full-scale drawings and a story pole as a tool to transfer dimensions. This process generates a comprehensive picture of, and guide to, all parts of the roof framing. 

Beginning with the plan view, section, and elevations of the design we then use a three-dimensional scale model of the roof. Through observation and discussion, we will demonstrate how the structure can be expressed in two-dimensional components. The roof structure will be broken down into four necessary two-dimensional full-size layout drawings. These will be used to locate timber layout lines. This process will result in actual lengths and cutting angles for common rafters, jack rafter, and hip rafters. The drawings will be made on a plywood deck, and timbers laid on them for marking. 

The final step of the workshop will be to fasten rafters to plate and ridge assembly, taking our work back into three dimensions.

About the Speaker
Gerald David owns GFD Wood Working, a restoration company that helps dedicated individuals preserve and enhance their homes. With a professional background steeped in tradition, Gerald has developed a keen sense and eye for the character of a building and its place.

Having lived in many countries and worked in many cultures, Gerald has both the experience and sensitivity that can reinvigorate any building and bring it back to past glory and make it work for modern needs. Preserving and adapting the built environment, and making it viable in a changing world spells conservation on many levels: historically, environmentally, and socially. By keeping and adapting our buildings we honor the generations that have made an effort before us and set an example for those to come.

Gerald believes that an inseparable part of working in the trades is the responsibility to educate the next generation. GFD Wood Working is committed to passing on knowledge both ‘on the job’ and in formalized courses.
