It will be 10" in diameter with 360 holes, ie one for each degree of a circle. So any angle that is a whole number would be possible. Depending on how this goes I might make another disk with say divisions of 7, 11,13,14,16,17, and 19 or perhaps some sub set of that.
The center hole is 5/8" and the other holes are 1/16" arranged as 2 arrays as seen here:
I plan to use my Shaper to cut the whole thing. It is going to be a lot of effort with that many holes.
The results should be reasonable but I don't expect the accuracy to be perfect, but it doesn't need to be either.
Material will be what ever plastic I might find in my collection in the 1/4" thick range.
No time table but I will try and make some time to do the whole project at one time. Really hot this week so maybe next week?? Longer away if I can't locate any suitable material and have to order something.
