When unboxing a new Tormek, be sure to save the little sleeve which covers the oexposed part of the shaft. It keeps the shaft from shifting or falling out. I recommend making up a couple spares from short pieces of PVC pipe. Schedule 80 pipe works well. The outside diameter is 5/8". The inside diameter is a bit tight to fit over the shaft, however, reaming it out with a 31/64" or 1`2mm drill bit makes it fit well. A piece of plastic pipe a little larger works fine, also. it won't fit snugly of the shaft, but it's the ends which hold everything together.
Always remove the grindstone and place the spacer over the shaft when transporting your Tormek.

That is good fodder for thought to remember. First I have to replace the grinding wheel and the shaft before I can remove the wheel for transport. :-\
