How to make a mini milling machine- manual or CNC!

Step 12: Make the handles

Drill a 1/4" hole into the center of each of the 2 1/2" long Delrin pieces. Drill a 5/16" hole toward the end and drill and tap a hole for a set screw for each hole you just drilled. Insert a 5/16" Aluminum rod into the outer hole and secure it with the set screw. Slide a 1/4" washer over the ACME rod and then slide the handle onto the ACME rod and secure it with a set screw.

You could make the alum handles so they spin, chuck them in drill press and file a groove, sand down the rod a little for clearance. Round off the end of the set screw, tighten, then back off a mite. I like your work! what have you worked on it?
