Attaching the spool drive wheel

So with it raining cats and dogs only 2 days after my wife moved all the table saws out to a new shed she built, I've been puttering around looking for some other things to do inside the house.

I polished up and shellacked my brass tracker bar tubing, and while waiting for that to cure I thought I'd get the spool shaft drive wheel fixed into place.

After thinking of various possibilities and looking around at what I had on hand, I decided to attach a black oxide shaft collar to my wooden spool drive wheel. I have a bunch of small roll/spring pins and I figured that I could drill holes partway into the shaft collar sides so that the pins would sit halfway in. The protruding parts of the pins could then be secured into the wooden wheel:

Driling was a little tricky but using some vise-grips to hold the collar under the drill press made it a little easier.

I then slid the spool drive wheel and the shaft collar onto the shaft to align them and then pressed the shaft collar's pins into the wooden wheel to mark a couple of drilling points.

I then drilled into the wood, pressed the collar into place, and gave the collar a coat of silver paint.

I put a nylon bushing on the shaft and then slid the collar/drive wheel unit onto the shaft.

I'll cut the shaft a little more closely when I get all the mechanical stuff finalized.
