I’ve been working on the my new pickup winder over the last few weeks. I started with these blocks of MDF…

 

From there I screwed them together and added a shaft and face plate…

I took the face plate over to Bruce Johnson’s shop where he trued the wheel on his lathe for me. He recommended that I swap my bronze sleeve bearings out for some sealed bearings. I bought some on eBay for a few bucks each.

From there, I tooled these brackets from 6061 aluminum…

 

And attached them to the plates…

In order to make the stepper calibrate with the traverse drive screw, I had to make a 20:1 gear ratio. I used the pulleys and belts that I put inside of the blocks.

Once I got the whole thing together, it looked like this:

Here it is with the face plate and main drive installed. Next, I have to build a base and wire this bad boy up. Oh, and I have to write the software.
