Ring Test on a grinding wheel.

[Ultradog MN]

I'm in the market for a couple of large grinding wheels for my pedestal grinder.
Connected with a guy from IA who has one that would serve.
I asked him to do a ring test on it but he didn't know what that was.
So I found this youtube video and sent it to him and he tested it. Wrote back and said it rings like a bell.
I will meet him next Friday at the Lesueur swap meet to buy it.
I'm sure there are folks here who will say this is old hat. But likewise there will be those who have never heard of it.
Anyway, click on the video for a great demonstration.

not to be that guy! and been a long time since i looked at the OSHA standard but i still think they have verbiage in the standard about doing this before use.

High school shop teacher showed us how to "ring" a grinding wheel.

Our school shop had a nice big double wheel grinder mounted on a pedestal. You'd shut it off and it seemed to coast forever. The shop teacher considered it to be a dangerous machine, and he had a list of common sense rules that we were expected to follow. One of the students brought in a shoebox about half full of badly abused chisels and screwdrivers. He was dressing up the chisels and discovered that he could drop one between the wheel and the tool rest and it would "dress itself". He finished the chisels and dropped a big screwdriver in where he had been destroying the chisels. It sucked in and shattered the wheel, sending pieces flying across the entire shop. Nobody got hit with any of the shrapnel. After things quieted, the shop teacher said, "Come over here everyone and see what William has done".

Thanks for posting that! Many don't know how to test a grinding wheel. NEVER use the side of a grinding wheel either.

I've heard that but don't understand why. I guess I've been lucky because I've used grinders that people used sides of stones regularly. It happens when stones are worn out and people need a flat spot for chisels and such. Those that brag of ability to sharpen drill bits on grinder often use side of stone.

When I was in T&D work we always did a ring test on the 6 inch wheels. There was a rack at the grinders holding around twenty or thirty wheels of different grits and hardness. Constantly changing them for different jobs and you never knew who used them before. What's really scary is a 30x4 inch wheel on the big surface grinder blowing up.

Do a ring test on your grinding wheel before ever mounting it to your grinder.

I've always sharpened bits on the of the wheel. Guess I better dress up my wheel and do the job fight. Thanks Ultradog and everybody else that contributed to this thread. RB

¿What else would you sharpen a drill bit on but a grinder?

You could use a belt sander. Ron MN

I was in the toolmaker profession for 15 years. Never did I skip a ring test, it just became automatic in your brain. As you came up through the apprenticeship you learned to watch the really good toolmakers.

They would rough sharpen a drill bit on the bench grinder. Then they walked over to the 24 inch disc sander to put the finished edge on. There was really no better way especially on large drills where the flute you were sharpening was wider than the bench grinder wheel.

...NEVER use the side of a grinding wheel either.

...Except on a form grinder.

Or a Blanchard grinder.

Or a Hertlein grinder.

Or...

You get the point. Every "rule" has exceptions. A more correct statement would be to avoid using the sides of wheels on general pedestal or bench grinders, NOT designed for that.

Right! I assumed everyone understands that; yep assu me.

Sorry I meant on the side of the wheel. That's what happens with huntin and peckin. Brain goes faster than the fingers or something like that. RB

More AI BS. The guard flies apart but the wheel is still there and no wheel debris on the bench.

Correct!
