Holy Grail for Roof Framing Geometry

There are no decimal points in Euclidean Geometry using a straightedge and Compass.

I deciphered what Euclid was drawing on the plaster tablet in 200 BC.  
The Euclidean Geometry for the Devers-canted hip rafter head cuts. 
Using the roof surface angles, the profile rafter slope angle and the valley rafter sleeper angle you can draw out the Devers hip rafter head cut and foot cut angles. As well as the jack rafter and purlin rafter head cuts.

    This woodworking book contains a great deal of details about wood working. The book also shows several designs and explanations on the materials useful for different woodworking processes and the directions on completing different processes properly. In other words, I`m happy using this book, specially in the procedure of understading about wood working.?

  2. I’m not that much of a internet reader to be honest but your blogs really nice, keep it up! I'll go ahead and bookmark your website to come back in the future. Many thanks
