I know all you Dudes and Dudesses are grown really smart people ....right?
Why else would you be on here talking tractors
Well, please be careful. I got a call last night late asking if I could do a graveside sermon Saturday. The regular minister is out of town.
Seems a friend went by a store (and I will not mention the name), and got this great deal on a bench grinder. He figured he got a really good deal. Sure, it was made elsewhere, but the price was right.
Well he set it up and used it for about 5 minutes and the grinding wheel exploded. He was using the wire brush wheel so his son says, but the other one exploded and the flying pieces killed him. He was wearing safety glasses, but the stone hit him in the temple.
If you get one of these things...look them over real good. If you have any doubt...pitch the grinding wheel in the trash and go get a good grinding wheel to put on it.
Remember...we do not know where some of this stuff comes from or how it was treated in shipment. Go to a store you can trust and get a good wheel and put on it.
Please be careful and learn from others.
These things are dangerous.
Bill

 I had one blow up! Re: Please be careful in reply to Bill46, 03-30-2006 08:59:45  
Lucky to be here to tell about it!
Here is what happened, it was in a company shop. I was grinding a small part, it got pulled out of the vise grips I was holding it with. The grinder a big 1.5 HP baldor with a very good stone, USA made. But the grinder was bolted to a steel table, since the gaurd was to large to clear the table they had cut the bottom off to bolt the grinder down flat on the base. When the part flew out of the grips it got sucked under the wheel and jammed between the wheel and table, it split the stone and flew out but also broke the motor casting and the gaurd casting. The company was more worried about the broken grinder than if I was alright. Well I was, cause all parts missed me, but sounded like a stick of dynamite went off. Said they heard it all the way up to the front office. I left that jerry rigged outfit very soon.

Not long ago, I had 2 wheels to explode, in several weeks, in a surface grinder. I decided to stop using the cheaper wheels. I broke & tossed many hundreds of dollars worth of wheels in the dumpster. Now I only buy & use wheels made by Norton. They cost more, but much cheaper than hospital bills. My condolences to the family.

Very sorry for your loss. I ran a camshaft grinder with a 20" wheel and 5 hp motor. EVERY time before you started it you would rap your knuckels on the side of the wheel and it needed to sound like ice in a glass. Even then we still stood to the side when we hit the ON switch and waited til it was up to full RPM before we got in line with the wheel.
Thanks for the reminder that you , me and all of us can never be too careful.

 ring test all grinding wheels before use in reply to Bill46, 03-30-2006 08:59:45  
You can ring test a wheel by holding it in the spindle hole and lightly tapping the stone part with a screwdriver handle, if it has a sharp ping sound to it then it is a good wheel, if a dull thud it is cracked---then throw it away and break it in pieces to prevent somebody from using it.

Not necessarily damaged in shipment, my boss bought a cheapo Clarke grinder, and I bet the wheel that came with it is at least 1/4" out of true, side to side.

Many grinding wheel are out of balance.They can be ok as far as being round, but will vibrate when running.Ring test all wheels before using.Test for balance on a lawn mower knife balancer,you will be surprised how many wheels that are far out of balance.If you find a wheel that doesnt ring , break it up.Dont use 3600 rpm grinders, spend a bit more for an 1800 rpm unit.Good grinding wheels cost money, avoid import cheapos.

saw a movie on grinding safety years ago, they can be very dangerous. NEVER!! stand in front of a grinding wheel whenever it first starts up. Always inspect for cracks prior to startup and using. better safe than sorry. just my 2cents worth

I read or heard somewhere that a grinding wheel should ring if tapped lightly. No ring means a crack or flaw in it somewhere. Any truth to that?

Yes, that's exactly right. You would want to hang the wheel by a coat hangar through the hole so nothing is touching the sides of the wheel, then tap lightly on one side with a piece of metal rod or the wrench you were going to tighten the nut with. If it doesn't ring, it's cracked. Sad story about the man with the new grinder. Probably damaged in shipment. Condolences to his family.
