I recently bought this tool grinder from HF:

I have a couple of newbie type questions:
1. It came with two green wheels, which have a metal plate on the back side, and then a ring-shaped grinding stone attached to the metal backing. They do a pretty good job of sharpening brazed carbide bits, but they are slow on HSS, and heat up the bits pretty quickly. Also, one of them seems to be out of balance. I'd like to try an aluminum oxide wheel. I checked Enco, but couldn't find that style of wheel. Can anyone tell me what that kind of wheel is called, and where I can get such wheels? What is the best way of trueing these wheels?
2. The table tilt mechanism is poor- it is hard to move the tables, becasue they bind. I have played around with the alignment of the parts, and gotten a little improvement. Does anyone else have this grinder, and do you have any tips on getting the table tilt mechanisms to work smoothly?
