So, I'll say I advanced the runner on this one.
Not a home run, but not an out either.
Attachment 230592Attachment 230593 This jig is crude as it was really just to prove the theory out. The depth is much more consistent now and I can control the parallelism of the flutes. Just need to build something beefier.
Attachment 230594
Have to make a better degree stop for the protractor gauge, maybe out of thin gauge steel with a notch at the exact degree desired. Either that or drive an encoder with a display cause that is the absolutely break point for this design. The 60' spacing has to be exact, like + or - 0' or it's not gonna look right.
Cheers.
