What this project is all about…

It’s to make a rotational axis for my lathe. This is so I can do milling/engraving on cylindrical objects. Such as rings, and pendants. I can even use this to help rough out gears before hobbing them.

“Gear Hobbing” is the process of grinding/cutting out the teeth on a gear.

The spiggot machined. It was a pain to machine, but I felt pretty good when I was finished making it, as I machined it exactly to size. The error wasn’t measurable with the measuring tools that I have.

Spiggot for the worm is almost completed. I still need to put in the set screws for the lathe spindle shaft. All I need to do is drill two holes 90° apart, and tap them.

Worm Spindle, this part is the shaft that I needed to mount the worm to. It’s pretty precise; I think I’m about 0.01mm off from where I really wanted to be. But it shouldn’t affect anything, and well within tolerances of what I need it for. When I drilled the spring pin hole, I wasn’t exactly centered, so I drilled into the shoulder of the worm just a little. This shouldn’t affect anything as well. The spring pin was 1/16″, and had to be ground down, due to the pin and teeth on the worm gear were knocking. Out came the dremel clone.
