I have tried to post a picture of the grinder I have, but have been unable to. Not sure if it is because this is my first post on here. But, here we go. I am not sure of the make of the grinder but, there is an unidentifiable label on the handle side that looks like a squished diamond but otherwise unreadable. On the other side it has "BK22" on the housing just below the shaft. My problem is that the shaft is bent and I don't know how to remove it. It may have been pressed on as it isn't held in place by a set screw. I'm wondering if I can just tap it out with a hammer. Any info would be helpful. Thanks
