I Forge Iron

2''x 72'' belt sander/grinder made from a 6'' bench grinder

What's the HP rating on the motor? 2x72 needs some significant oomph, so if your grinder doesn't have enough power, you're setting yourself up for failure before you even start.

for the record, when I last bought a used 1.5 Hp motor from the repair shop,  I paid $75.  So its not too bad buying the correct size motor to build a grinder, Save the Ryobi for a buffer

I have a similar size bench grinder that has a wire wheel on one side and a regular grindstone on the other. The wire wheel gets a lot of use for cleaning up residual scale, and the grinder is mainly for sharpening drill bits.

They make something called a Multi Tool Grinder for bench grinders.  I started out making knives with one of them before I built my 2 x 72 grinder, and it did quite well.  I think they are reasonably price IIRC and come in different sizes, I used the 2 x 36 and still have it.
