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.
