Being a total novice at this, I really had no idea that Mach was asking for.
As for the forum, I must say that this forum, unlike many, is very helpful and focused on the topics and not on flaming and personalities. A refreshing change from some.
Once I just went with observation instead of calculation, it only took a couple minutes to figure out what Mach wanted. It would have taken much longer to collect and post all of the specs and wait for an answer.
My 4th axis is actually just a stepper powered spin index, so it already had a degree wheel on it. I posted pics in the 'show and tell' section.
