If you read some of my other posts, you know I like making tools for the Shopsmith. I thought you might be interested in the following photo.

As you can see, I have been building a light duty belt grinder that fits on a Shopsmith. The wheels are 6" plastic caster wheels. It takes either 1” or 2” wide belts in any length from 42” to 60”. There are 1 and 2 inch platens that bolt on behind the belt. I made a couple of work tables for it, second one seen here.

I would have preferred ball bearings rather than sleeve bearings on the drive shaft but I used what I had on hand. It has an adapter to take my wood lathe chisel sharpener on the right side. It can be used without the work tables as a slack belt grinder and with a bigger drive wheel too. It runs pretty good.

I am writing it up and hope that Home Shop Machinist magazine will publish it. (I have a little two page article in the current issue of that magazine!)

I am interested to see if you have any comments, suggested improvements, etc to make. I am adding a spark shield over the top wheel for safety.

I think that is a 2" x 42" belt, and thanks for the comments!

Here is a picture of a 10" wheel mounted with a 1.5" x 60" belt. I think it was a lawn mower wheel in a previous life, that I trued up on my Southbend metal lathe. It is usable but not a very good drive wheel.

The base is just two 6" long pipe nipples screwed into two 4" floor flanges and then bolted to the extruded aluminum piece by 5/16" bolts, the heads of which nicely fit the "T" slots in the aluminum. I turned the nipples down so they slide into the SS spt sockets easily.
