Grinder Wheel Balancing

I purchased a Harbor Freight Grinder and it vibrated excessively. This video shows how I balanced the grinder wheels to eliminate the the vibration.

WOW! Thank you for posting this. I have the exact same grinder and same problem. I thought the only solution was to bolt it to the floor. Definitely buying that kit! THANK YOU!

Well done. Final balance should be done after dressing. I wish this was available for my 12", I will probably have to turn something up if it ends up being a problem.

Thanks man. Great video

It almost looks identical to my Sears 6 inch Craftsmen bench grinder that I bought over 25 years ago, it has the same style of base, tool rest, plastic shields, and gooseneck work light.

Same with my 15-ish y/o Porter Cable as well as many others. As with so many standard tools, many companies use designs and components from Chinese/other companies, which mfg. given components. This is the case across many industries as well. E.g., auto parts, electronics, etc.

Did you correct the roundness first? Without it the mass balancing doesn't make much sense.

[@eddiec1961]

Did you check the vibration with the better quality wheels without the balancing kit.

[@tzavitz]

Did the balancing kit have the adapters to take the 1" arbor grinding wheels down to the 5/8" fitting for the machine?

good!

I am a little surprised that you began the balancing with three weights. I thought that the correct procedure is to start with two. This is my take on the procedure: first, check balance with no weights, and mark top dead center and bottom dead center. TDC is the light side, so place two weights on either side of the mark, equidistantly. If TDC and BDC swap positions, it is a matter of moving the weights away from each other, still equidistantly from theTDC mark, until balance is achieved. If two weights are not enough to overcome initial imbalance, add a third at TDC. Although, as I think this through, beginning with all three weights at TDC could still work, and save the trouble and time of adding the third later. Ok, my mistake.

Where did you buy the balancing kit?

[@mahirdiwan517]

Same question bro

[@Momoka7]

I found that thing on Amazon... Oneway 2272 5/8" Grinding Wheel Balancing System but it costs a whopping $77.33... ugh.

[@dpeter6396]

It looks to me like the bearing in the balancing stand is very sticky from the way the wheel stops moving suddenly. Until that is fixed you won't be able to do any precise balancing. Too bad Oneway wants so much for their gadget!

Harbor Freight... I bought a Grinder from them... impulse buy... and since I didn't need it right away I didn't unpack it. Yeah... the base was !@#$%& PLASTIC... and it probably broke on the ship from China to America. When I finally opened it, oh wonder I bought a piece of trash... yay.😒 So now I bought a DeWalt... is a much higher quality. However... one of the grinding wheels... is wobbling. But... that Oneway 2272 5/8" Grinding Wheel Balancing System costs a whopping $77.33 !!! WTF for just some plastic pieces and that "balancing" piece! That cost you more... then the whole Grinder! lol!

Ping me if you find a 3D printable equivalent:)

This video should be called "WHAT I BOUGHT TO BALANCE MY GRINDING WHEELS" instead of wasting peoples time doing an infomercial.
