Rotional Axis Project

The old adage of “Measure twice, cut once�… is so true.
Well, I didn’t measure most of the stuff I’ve been playing with lately, nothing bad has happened yet. I did have a mock up, so I cut by lining the mockup to the part.
What did happen is that I received two set screws from a local shop, and the package that it was taken out of said it was 6-32. Well, the set screws aren’t #6-32. But I have a nicely machined, tapped, and completed motor coupling that is ready for two new #6-32 x 3/16� setscrews. Even ¼� if need be.
Completed:

1. Spigot
2. Spindle
3. Spindle housing
4. Stepper Motor coupling
5. Motor mount spacers

To complete:

• Locking ring for spindle
  • bore it out
  • drill out holes
  • tap
• The mounting bracket now.
  • Machine the edges
  • Machine the spindle hole
  • Drill out bolt holes for motor mount.
  • Machine the bolt holes to mount the bracket to the spindle head.

To buy:

• #6-32 x 3/16â€? or ¼â€? length.
• Mounting bolts – measure what they are. I believe they are M8 x 1.25
