I occasionally like to use a belt sander/grinder and got some 48 and 60 inch belts at a surplus store. I found the plans for the EERF grinder here: http://blindhogg.com/blueprints.html
and I had some bearings, aluminum wheels amd a nice drive bearing assembly from the same surplus store so decided to make a SPT out of them. I made a round and a flat workhead for it. I decided to use baltic plywood instead of steel because I thought it is strong enough for the light duty I expect to use the sander/grinder for. I will be painting the EERF sander/grinder grey later, after a shakedown period. It seems to work fine and the SS variable speed is nice with it. Some photos are attached below. If anyone is interested in more detail, let me know.

Your EERF (whatever that stands for) is really COOL!!! If I had not recently bought a SSS (Shopsmith Strip Sander), I'd quickly begin copying your effort.

Thanks for showing us your machine and including the plans from Blindhog Gunworks.

Nice work and a very cool sander.

Very nice.
Darned if I can find what EERF stands for though.
Obviously not the Equine Eye Registry Foundation
or East of England Rural Forum
or Eastern Environmental Radiation Facility

EERF is FREE spelled backwards, refers to the fact that the plans are "free". One of the sites below uses that name so I did too. Note that I did not follow the plans exactly when cutting out the plywood; where feasible, parts were made wider to avoid having bolt holes too close to the edge of the plywood. The chromed arms of the sliding workheads came from a junked exercise machine. The thumbscrew that locks the chromed arm engages a t-nut pressed inside the socket. The brass drive hub was made to fit the odd size of the shaft. Most bolts are 1/4-20. More on the EERF sander/grinder:

Similar to people making their own Sand Free version of the Sand Flee.
Maybe they should rename it to the Sand EERF?

Thats a great job - Thanks for sharing the pics. Alec
