Grinding Wheels

I have eight different wheels I use. The back left is a Rayspan Expandable Drum that I use with 80, 100, 220 and 600 grit belts. Back right, as well as the second from front right, are Crystalite Turbine Wheels, in 40 and 60 grit diamond. Far right is a 30 grit diamond wheel that I picked up from Craig Ratzat. Very aggre- sive, indeed. Next is a Crystalring diamond, in a 100 grit, followed by a 60 grit Kingsley North Diamond Flexwheel. The last two wheels are both Silicon Carbide Grinding Wheels in 220 grit. A little variety to get most any grinding job done...
