The critical difference was the insideface was not a show face so the angles I usedwere fudged to close the joints on the outsideand fill gaps on the inside. I was familiar withthe trig at the time but never perfected its useonce I got close enough for what I was building.

I can not verify what your trying to prove because . I’m not familiar with rest of the problem with the staves.

That just about blew my mind. I haven’t been the same since. But when it came to subtracting 2 from 2, and arriving at 0, I was a goner. Don’t even get me started on division….. hehehe….......
