2 x 72 inch Revolution Belt Grinder (aka The Metal Muncher!)

Belt Grinder Radius Forming Jig:

I just finished up this radius forming jig attachment for the belt grinder. If the part your working on has a hole, this will allow you to form a radius around it. Jig simply drops into the existing table arm allowing adjustment in/out and up/down. Can work with both the contact wheel shown or the flat platen.

I have created an assortment of pins ranging from 1/8" to 1 inch but others can be made as needed. They are all stored on an aluminum rack for safe keeping.

Table inward movement is done by use of the handle that rotates the table in and out. An adjustment knob can set the depth of this which is good for making repeatable parts.

Just install the correct size pin, place part over it and rotate left and right while slowly bringing the part into the wheel. It literally takes seconds to produce a beautiful formed radius.

In addition, the table tilts so forming a beveled radius is just as easy!

Forgot to mention that you can also produce circles with this jig. I made a few today to test it out. I did one in 1/4 inch steel plate and I sandwiched (2) 14 gauge plates together and did both together. Worked great! I also added a push down handle to the belt tension arm.

Nice build there!

Sorry about stealing your picture.

But i was wondering that could this be useful?



If you cut the table to follow the shape of the belt ( black line on the picture).
Then it would be possible to place table closer to the belt, and use that tilted lower wheel for grinding internal curves?

Looks like a great idea to me! Maybe make a separate table just for that. The possibilities seem to be endless with these grinders. That's what I like about building my own tools.

Thanks for the input!

It's just an amazing job! I salute you

Oh no, he's still at it! Another attachment!

Today I introduce a bevel jig invention for the 2 x 72 belt grinder.

The pictures and text tell the story. Basically it's used to produce an even bevel across the part, all the way around or from part to part depending on the situation. Repeatable! Trying to achieve this by hand is difficult, but not with this tool!

P.S. don't you just love the adjustment wheel? I bought that 4 inch round outer ring at my metal supplier last year and was just waiting for an excuse... You can also practice your driving but sorry, the horn doesn't work.
