  • Grinding Wheels

    I have two bench grinders. One I use for wire-wheels, buffers, and for coping my 4130 tubing, the other is for sharpening / grinding.
    I am looking for recommendations on grinding wheels. I bought the grinder with two silicon carbide stones that were out of balance when I brought it home. I've been using it for a couple of years and finally threw away one of the grinding wheels. I bought another wheel at Harbor Freight.... what a bunch of crap. I am managing to use it, but it has a lot of run-out. I've tried shimming it straight without much success. I have about 200# of steel plates stacked on the bench to keep the bench-top from vibrating and causing my tools to dance off onto the floor.

    What is a reliable vendor for grinding wheels that I can buy without waiting for my next SS check to arrive?

    Might be a stupid question, but I have to ask: Are you sure both shafts are true?
    Norton, Sait and Carborundum are good wheels.

      Check that the ID of the wheel hole is only a few thousands bigger than the shaft/arbor OD. If it is a cheap grinder, it may have had bushings on the shaft or in the original wheels that have gone astray..... If it vibrates that bad the wheels may explode....Very dangerous! Be safe.

        I always true my grinding wheels with a tool like this: https://www.mcmaster.com/#grinding-w...ssers/=1ah1c7z

        And I finish the stone with one of these: https://www.mcmaster.com/#grinding-w...ssers/=1ah1cya

        I was taught that when I had the stone just right I could touch it with a finger and it would feel smooth. I am very careful when I do this.
