« Part 1: The base and rollers Part 2 of Shopnotes 126 Belt Sander series Part 3: Belt Guard and Power switch »

So I decided to paint the base winter grey. The pivot arm and related parts used polyurethane.

I like how the base turned out since it was old growth pine. I cut a simple 45 all around it.

The pivot arm is some kind of foreign oak type of wood. It is very hard and was smoking my table sawblade.

The motor I am using a 1/3 HP Ge from the 50’s. It still works great. At first I had the 3 inch pulley on the sander and the 2 inch on the motor. I found it ran too slow. After switching them it worked much better.

When I made the platen I had forgotten to cut the vertical slot for the rest to mount in so I had to do it after it was assembled.

I found the tracking knob did not have much tension on it so I put a spring under the washer. That really helped and it stays put now. When I first assembled the rollers and put the belt on it tracked off center. Everything looked aligned but it was off. You can see I had to make a 1/2 inch thick spacer between the top roller and pivot arm. Now things line up like they should.

For the platen I used 12 gage stainless steel. I also put a graphite pad on it. I used rubber cement glue to hold it on. So far it seems to work.

When I was locating parts I looked for knobs that are called for in the plans but they cost a lot. So I decided to make my own. Not the greatest but I like them. I turned them on my cheap wood lathe.

I think this is long enough. Next is the tool rest and power switch.
