Philip,

You made a beautiful and very functional rafter square. It would be an interesting tool in a smaller scale for use in the shop.

I think the builder of any house with your complicated roof line would appreciate seeing the model before building full scale. I can see why some custom home builders are prefabbing some of the more complicated roof components offsite (e.g., barrel roof dormers and eyebrow dormers) rather than stick-build onsite.

Thanks for the tool posting, Paul
