How To Stop A Bench Grinder From Vibrating Using Static Balancing

If you have a bench grinder or other wheel grinder this video shows you how to stop it from vibrating. Check out our Podcast directory.libs...

This by far is the best explanation that I have heard online, it beats sticking weights onto the wheel and all the other unsafe methods used. Thank you for sharing this excellent method with us.

[@shanemeyer9224]

This is absolutely the best and safest method I have seen to balance grinder wheels!!! Wow I can’t believe people are glueing and grinding things, this is truly the best way I will never forget this tip now

[@amichke]

Most EXCELLENT video! Very helpful! For those of us who are "weekend only" shop people, I have a suggestion to everyone: Using a Sharpie, mark the Loosen/Tighten directions on each of the outer washers and include the size of the retaining nut. Reduces the Homer D'oh(s)!!!!!

[@trevorspary134]

That has got to be the best tip ever and so easy to do. Appreciated

[@hopelessnerd6677]

I'm late to the party, as usual. This is a fantastic idea! It's a safe and solid way to balance a grinding wheel. Looks like a marketable product. Good job!

[@randywl8925]

I love this method. I do however agree with someone that responded saying that this puts the full clamping force on the piece that you made directly on the entire edge of the stone. Meaning that entire surface of the plate you made is being pressed against the grinding wheel. The factory washers do not clamp on an entire one and a half or two inch surface of the washer. They clamp on a rim area about three eighths of an inch wide. I totally agree with what this guy said. With that said, maybe you could cut out, and glue on, a thin gasket of sorts maybe three eighths of an inch wide and adhere it onto the back of those pieces you made. It would be like a 2in by 3/8 diameter gasket. Look at the original washers and the contact area they have on the stone, then duplicate that on to the pieces you made. If you left the original grinder washers on the inside then make the gasket I mentioned that exact same exact diameter, so you create an equal clamping load on each side of the stone. I'm new to this subject but I read that people use cereal boxes as replacements for the paper that originally comes on grinding wheels. If you take one off, sometimes it takes the paper with it in bits and pieces and makes an uneven surface. I have that problem and I'm looking at totally removing the paper and replacing it with another surface. You don't want metal directly on the grinding stone, you want a cushion, to stop direct contact between metal and stone. Cardboard from a cereal box is what I seen come up most often. Thanks for the ideas. I've measured out some lead solder that equates to the amount of weight I need to add as a counterbalance. I'm thinking of pouring lead inside of the clamping washers. I know exactly how much I need and lead solder works to balance the wheel. The grinder washers have cups and I simply folded up some lead solder into that cavity with the correct weight and it worked. I removed the grinders original washers and I'm going to melt some lead into that cavity as a counterweight. With two washers if I melt the equal amounts of lead, one into each half, this will balance the machine. I'm not sure how balancing the machine works compared with balancing the actual stone. One would think you would need to balance the stone, not way back towards the shaft. Film at 11 so they. ..... Others say, hold my beer 🍺 watch this. 😂 Thanks again and also thank you to the other people that commented. .....and now, hold my beer watch this. 😁

I think that is the best informative video on balancing, Al you shine

[@allenbowick4716]

Always loved watching your tv show, now I have something else to watch. You Canadians are spot on.

[@gordonallison1055]

Thanks, my new grinder currently sounds like a 747 on take off, this will help loads

[@channelview8854]

Thank you very much for this information. This is by far the best video on this subject that I have found.

[@peterschmelcher2754]

Thanks! My 20 year old grinder no longer bounces its self off the table or if bolted to a table everything else. I balanced the wheels one at a time on the motor shaft to include any motor unbalance issues. Used a 1/16" sheet and a 60 degree pointer angle but if I take it off again I will drill the washer opposite the pointer to increase the eccentric forces.

An excellent video and much appreciated.

[@geobrown9413]

Before you go to all that work, take all the wheels off and run without any to see that the problem is not in the grinder......not the best one to begin with. Add one wheel at at time, running, to see if it vibrates, mark it and dial in 1/4 turn at a time to get the best operation. If that doesn't dial it out, add washers like Dave Joseph suggests below. That is how I fixed my Baldor's vibrations.

[@sky173]

What a great idea. Thanks for sharing.

[@das250250]

Great solution and safe

[@7natcho]

Good tip , makes sense ! I had small issues like that before . Why a King grinder ? I have never had luck with that product line . I purchased a Metabo DS 200 8-Inch bench grinder and 80% of vibrations went away ! I use a stone on one side and a braided wheel on the other side . I purchased a good stone dressing wheel (rasp) to eliminate the remainding vibrations . Maybe i have just got lucky but will definitely keep your tip in mind !

[@mlutescu]

that seems brilliant. Can't wait to try it.

[@blitzroehre1807]

Thanks for an excellent tip! Big thumbs up

Best ideas are simplest.

[@MrHomer1995]

Top idea

[@firebird77clonefirebird89]

Crazy. I've never seen this. Ever.

[@ajmac5735]

Perfect!! Now guess what i've got to do tonight....

[@iangolightly604]

Would have been interesting to see how much the water would have vibrated with no grinding wheels attached.

[@quocvinhable]

It's so amazing. Thank you so much

[@johnnydc7]

Great process! If my grinder has a brush wheel on one side can I balance that too?

[@flashgordon6238]

You can try the same method here, but I would check the vibration with only the brush wheel installed to see how smooth it runs without the stone wheel. I'm guessing you are talking about a wire wheel? There are nylon brush and fiber wheels as well. The balance with a wire wheel may change as the wires are dislodged from the wheel. Most likely the wire wheel with not cause too much vibration.

[@ckmoore101]

@@flashgordon6238 I have heard of people actually clipping off pieces of the wire wheel to do the balancing.

[@davejoseph5615]

Can't I simply buy some large thick washers with a 5/8 inch hole?

[@flashgordon6238]

You would need to make them non-concentric to counterbalance the heavy spot of the wheel.

[@stanimir4197]

@@flashgordon6238 if the washers are tick enough, having enough mass, drilling holes should be able to offset weight

[@mikefedele4521]

Food for thought to be honest I never really paid attention

[@TheDirtbikerdude]

👍

[@Tuberesu]

of course it's the best method - if you have a workshop that could house the victims of an earthquake. but not much help is your workshop is a 10' x 8' shed with not much equipment.

[@ghostwriter8631]

Why not just dress the wheel?

[@okidoke4822]

From what I know, dressing the wheel only gives you a straight front edge. It doesn’t balance the wheel. They are not balanced because of the way they are constructed, ie the density isn’t perfectly even throughout, so even if the front edge is nicely straight and flat, there can still be a wobble.

[@stanimir4197]

4:41 - he dressed it

[@mjremy2605]

If you don't balance the wheel first so it runs true, no point in dressing the wheel. First balance. Then dress. This is like getting a chiro adjustment on your back first, the deciding if one leg is shorter than the other and finding a heel for shorter leg. You adjust spine first.

[@randywl8925]

​@@mjremy2605 I don't know anything about anything but that seems totally backwards to me. If the wheels out of balance because it's lopsided, why not make it round before you try to balance it? I'm not totally disagree in, I'm just rolling this around in my head. If it's out of round, wouldn't you want a lob off the egg-shaped part of the round so it is actually round? Once it's round you can deal with the imbalance. Being out of round or lopsided, might be entirely why you're out of balance.

to the dude in the beginning of this great video, let it go grey and get a haircut from this millennia, trust me, you will be much happier not having to deal with the cover. It's not fooling anyone. when i did it it was liberating.
