Belt Grinder Ideas
Are you a DIY'er? Are you comfortable fabricating simple machinery? If so, you NEED a decent belt grinder, preferably in the 2"x72" belt size. You'll find a thousand and one uses for it once you put one together, and it's very easy to put one together. This page is all about the resources and ideas you'll need to plan your own belt grinder project.
Belt Grinders are great for blending smoothly flowing shapes, deburring, and generally improving the look of parts. For the latter, you also want to make sure the surface finish of your other machining processes is all that it can be. Check out our guide to Milling Machine Surface Finish Tips for some ideas.

McLurkin's Bader III
is mounted on its side to make it easier for him to do fine work. Note
the very small wheels and wrap around tool rest so he can get inside tight
makes some of the best grinders there are. This series shows off the
different accessory configurations they have available:
Here is the grinder. Note the
3 Configurations, left to right:
the basic wheel, slack belt grinding, and a platen grinding setup...
Metalworks offer the excellent KMG grinder:
It would be knife to turn this
grinder horizontally like McLurkin shows at the top of this page and then
use this attachment with a rest that fit nicely. You could really get
into some tight spots with it!
Tooling arm rack is a clever
accessory that makes changing the configuration fast and easy.
Here is the grinder sporting
a platen attachment, and a rest on the lhs photo. Note the solid CNC construction.
Minimal welding. Picture on far right is the slack belt attachment.
Or, how about a rotary platen?
Seems like it could take the place of several of the other accessories.
The actual "platen" is a rotary belt under tension with rollers.
Here is a variable speed JL

Check out the "Dream" KMG attachment, pretty cool!
Wilmont's Cool 3 Attachment Grinder
The rest is slightly reminiscent of the "Dream" KMG rest shown above. The Wilmont is a nice variation on the KMG and the site includes plans for a home shop model you can build.
The Australian Radius Master Grinder
It has 5 interchangeable contact wheels that can be indexed into position--these 3 plus the other 2 corners of the triangle have larger wheels...
They also make a hollow grinding attachment that's pretty neat...
