    When I put a belt on my 2x72 grinder it has a "shimmy" to it. I was told it is because the belt is skewed cut. Did I buy the wrong belts? I ordered them from Pops. Is this a common problem? Will it cause grinding issues?

    Make sure you have enough tension on the belt.

    What belt is it?

    Cheap belts shimmy far more then expensive belts.

    Also if you left the belt under tension over night it can cause the belt to shimmy. When I do this I turn the grinder on at high speed and let the grinder run uninterrupted for 20 minutes. This often will take the shimmy out.

    You don't have any grinding residue or other particles trapped under the belt do you? Does the belt track the way it should? Could be a defective belt. Is it only the one belt?

    Unless the belt specifies a specific direction to put it on your grinder, try turning it around in the other direction and see if you get the same result. It could also be you need more tension on the belt.

    i agree with more tension. also when you press your blade against the belt, if it moves to one side, that is also a sign of not enough tension.
