    The materials we run are typically all PH stainless steels in condition H900 OR H950. 17-4, 455, 465. The 14" size is not typical, just an exaggerated guess to better communicate our needs.

    Maybe you could use a shop vac to suck the coolant up. It sounds like a really annoying design.

    Congrats.

    It had to have been your wheel not being tight enough.

    Great work.

    Midget, quit being a tool and maybe try to help?

    Not all grinding wheel manufacturers code their wheels like Norton.

    I guess i should have said 100-I.

    I think I understand your issue.

    When side wheeling, you are grinding an arc, instead of a straight wall.

    That sucks for a brand new grinder.

    A lot of your grinding finish looks like it came from your dress. Like others have said, its tough with soft steel. It doesnt look like chatter to me.

    Like I said before, make sure your wheel is tight and that it is dressed true on the entire diameter. Chances are one or both of those possibilities are causing your problems.

    If you have a 46 grit wheel, start with that. It will be a lot more forgiving for you to learn with.

    As far as the chatter, make absolutely sure your wheel is tight and fully dressed....

    The drive cable is a pain in the ass. I used weights, it also helps to have a second person keeping tension on one end while you wrap. Make sure you have it on correctly, ie not upside down on the...
