we used to use a big ole flat hunk of grinding wheel to clean the top of engine blocks. Just a couple circular passes like sand paper laid on glass. I use old grinding wheels to hand clean up screw driver tips etc.. Yours is too rough to clean a chisel used as scraper. once broken always broken, no using damaged wheels ever and no grinding on the side. Sure hope that happened when you dropped it and not while it was spinning.

Little bit of JB Weld should fix that.
A reply like this might be taken as a real fix. A damaged grinder wheel should be tossed in the trash and never used again.

That wheel has never spun while in my possession. This is off of an old belt driven grinder that I'm restoring. The threads on the shaft were so torn up that I had to destroy the shaft and this wheel to get it apart. I made a new shaft. I'll put a new wheel on it if I ever actually use it. I've been restoring grinders and vises just for the fun of it for a long time. I actually use one of the vises I restored but never a grinder. They're all gifts or wall hangers.

A curved section of a broken wheel may come in handy one day. So will the curved section of an intact wheel. That's just extra stuff in a drawer to me that I don't need.

You guys crack me up. I'm surprised no one said cover the top of a potted plant with it. It will hold moisture while the plant grows through the hole.;):sick:

Job in High School was working as driver in a place that made die sets. When I wasn't driving, I got to run a blanchard grinder. Had a wheel crack, guy that was "supervising" me just wrapped it with a bunch of fiber packing tape and said I was good to go. Being a dumb *** kid, I believed him and went back to grinding. Actually stayed together for a few minutes, till it didn't. Grinding stone went everywhere, luckily the guard worked. Have very vivid memories of that exploding in all directions...

To everyone who says "throw it away" keep in mind that NO ONE intends to try to spin this thing again. The question is "what OTHER uses can it be put to?" Also go back to my original post; I never asked if it could be spun again. I may or may not be the brightest bulb in the box but even I would never try to do that. There have been some good suggestions so far. Any more?

The restore looks beautiful. I would "repurpose" those broken pieces as mentioned early for "HAND GRINDING". Grab some leather gloves... a chunk of that wheel... a project to grind... grab the chunk firmly and have at it. I have a stonework box I use to finish out stonework cuts... one of those blocks would work great to cut the edges of a cut stone.

Nice Paint!

I have a small honing stone that is useful or:
Deburring the edge of freshly cut metal
Dulling the freshly cut edge of ceramic tile. Gives the grout a little bit more to adhere to.
Cleaning surface rust off of some non-critical small part.
Squaring the end of a dull putty knife.
Quick touch-up of a lawnmower blade

Of course some GJ'ers may disagree with all of this and suggest the proper $5000 tool. ;)

That guy needed some broken grinding wheels shoved straight up his *** sideways.

There are lots of uses for it. You file a hoe or shovel, or pick, and then dress that with a broken piece of stone. Don't need all the pieces, just keep one. Have a piece of steel plate that is rusty you want to knock the rust off of? A broken piece of stone works great for that. Have some bricks with sharp edges you want to knock a tiny bit off? That works fine for it. I keep a couple pieces of things like that around, different grits. They don't take up much space.

If you have a wet saw for cutting tile, you can deglaze the diamond wheel by cutting through a section of a sharpening stone. It wears away the steel and brings up fresh diamond particles. One or two passes are all that is needed. I had to buy a stone to fix my blade after cutting some hard porcelain.
