I just got my grinder and cleaned up the castings. I hope they still make the shim kits for them. The grinding wheel seem to vibrate allot so I got another wheel form a local saw shop and ordered two from baileys but did not help. So I returned the grinder and got another, this one seems a little better it has more of an up and down wobble as apposed to side to side. I notice the stones don fit tight on the shaft. My question is, is this normal for this grinder and will I still get satisfactory results?
