If you ever get ambitious, you could build your own system. All you need are pillow blocks, shafts, a few goodies to secure wheels and a industrial sewing machine motor (1 hp DC, reversible).

The advantages of this are:

1) The motor can be reversed, which has the same advantages being able to reverse a lathe does;
2) You can run the grinder at speeds of from zero to about 2,500 RPM, so you can grind nearly anything with less chance of burning;
3) You can set it up for two, three or four wheels.

Mine makes grinding things that required a delicate hand so easy it’s indescribable.

Keep in mind, the frame for all this does not have to be built from iron.

Oh, and down the road and regarding your high speed steels, I second the CBN’s. Before them, I had a lot of dust. After them, I still do, it is only the steel from the tool, rather than the tool and the wheel.

Also, since you’ve, voluntarily, thrown yourself into the lathe vortex, you can look at the Wolverine set of sharpening jibs for gouges, skews and other things (you can look into making your own of these too. Captain Eddy has good info, for example). If nothing else, they are wonderful for re-profiling knives.
