Monday 30 April 2012, 9.30am - 5pm

A one-day workshop focussing on the German carpenter's craft of lining out full size and scale drawings showing the plan, and section, of a regular hipped roof. These drawings are then used to obtain every length and bevel required to cut the roof, before you have even touched a rafter!
This method, and variations on it, has been used extensively on the continent since the Rennaissance. It is used for all shapes and sizes of roof. This basic workshop aims to set out the fundamental principles that apply to all roofs. The focus will be in a hipped roof, and students will work out the lengths and bevels associated with a common rafter, hip rafter and jack rafter. Once these essential principles have been understood they can then, after further practice and instruction be applied to irregular plan roofs, irregular pitch roofs, polygonal roofs etc. A comprehensive set of notes referring to the workshop content will be given, so the students can both follow the work as it develops and enable them to apply it to their own projects at a later date.
