I bought a cheap (19.95) Harbour Freight 6"grinder that shook badly. I machined new washere and?took the armature out and squared up the shoulders that located the washers. Also made new shields from aluminum pans. Runs great and smoothly now!

In the Nov/Dec 2022 issue of Home Shop Machinist, there’s an article about building a fluid-balancing washer assembly to improve grinder vibration.
?
'Build the?Slawsher: A?Balancing?Ring for Grinding Wheels by G L Carlson PH.D.?‘
I've been working on reducing the vibration in my Chinese 8" bench grinder.? Adding collars for the inner wheel flanges to rest against and making new flanges (ala Harold Hall's "Tool and Cutter Sharpening").? I was cursing having only the 1" rest, when I re-found the steady rest mod doc in the Files section.? Did not have a need for this mod until now.
Putting the rest in the mini-mill vise, with the middle slot edge aligned with the left side of the vise, it was just some up and back on the Y to give me a nice opening for my grinder shaft to fit through.? I wound up with a generous 0.885", and I could have gone even further, since I left about 1/32" on each side.? Maybe one day I'll build a larger rest with a nice flip top like many of the Myford guys have.
