What’s the matter, too deep for you?

This guy appears to have the trig worked out:

I used to make conga drums when I was
younger. The critical difference was the inside
face was not a show face so the angles I used
were fudged to close the joints on the outside
and fill gaps on the inside. I was familiar with
the trig at the time but never perfected its use
once I got close enough for what I was building.

If I understand what you want to do, M. Wandel made a handy chart for staves.

Your original formula was wrong but you got the right answer. should be 360 divide by number segments divided by 2 because its the complement of the angle to get 15 degrees. I can not verify what your trying to prove because . I’m not familiar with rest of the problem with the staves.

Heck yeah, man. I learnt that 2+2 = 4, and 2×2 also = 4. 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…....... Jerry (in Tucson)
