I took a spare feed stop knob and sanded it down through the grits. 120, 150, 180, 220, 320, 400, and 600.

150, 180 (forgot to get a picture of 120)

220, 320. Not unlike sanding furniture you could stop at 220 if you wanted to. Establishing a uniform scratch pattern was done here so if you don't like it too shiny I suppose this would do.

400, 600.

This is after taking it to the buffer with some black emery. I'm not sure how much more shine it could take but I'll go through the full process just to see the final result.

I'm not a huge fan of the polish per se but I do like the consistent and clean appearance that it imparts to the whole. My concerns are how to address the curved and tight spaces such as the table height in the background as well as rounding over edges. It looks most apparent to me at the top of the barrel; there is clearly some curvature there. As for the polishing I just need to know how to dig all the compound out of the checkered area and letters so I don't cross contaminate.

You need to instruct Jonathan to hold the spray can upright when spraying.:)

Looking at the results, it appears to me that Jonathan is doing an alright job of spray painting. I'd let him paint mine any time he wants. Keep up the good work, Dad.

Finally!

It wasn't quite an extra six months, but it was close. Main unit has been done for some time but the jointer was held up for a bit; I think it was worth the wait. Short summary of improvements:

- Faster
- Smoother
- Quieter
- More secure (no parts missing or falling off)

Notes on some of the polishing/painting in a later post but for now here's some shiny pictures.

Beautiful job!

Jonathon looks as proud as a peacock. No doubt that machine will still be in the family when it is a hundred years old. :cool:

"Polishing"

Polishing up the speed control handle, speed control dial, and sawdust port cover represent something of a challenge. One of the big kicks I got out of the rebuilding process was when I was able to think of a solution that wasn't brute force; it made me feel all grown up.

In this case it was how to sand these pieces down without rounding over and destroying the crisp lines. I had planned to use my palm sander in a vise but a few parts of the knobs I'd polished had been rounded over. Not bad on those parts but it would be glaring on these. The pieces are round so I kept wracking my brain trying to figure out how to chuck them into my hand drill. Then I remembered how the rebuild began; I'd blown the switch while running the LATHE! I'd already reassembled the head stock and bench and I had a Barracuda chuck (thanks Pop!); it seemed right that its first use be to help restore the Shopsmith. So I chucked up the pieces and used a piece of plywood to back up the sandpaper. The flats on the handle and cover were sanded out on granite. Turned out pretty good.
