Those templates are very impressive.
Tom White and I have had several enjoyable discussions about his the Bird of Prey (BOP) 36 Ultra-Light I built for him and his build of my BOP 12 Ultra-Light. Tom offered to make an aluminum template for me, if he could use one for his build. After further discussion, Tom was kind enough to make me aluminum templates for the BOPs that I have been recently building for other glider kite enthusiasts. The following pictures are of the templates.
