Jeff, thanks for the response.  I was really babying the grinding wheel, using the flat of the stone and not really pushing hard.  When one wants a fine grind, do you use the same technique, the corner of the stone and lots of pressure?

Jeff, I am having a devil of a time sharpening a Robert Sorby 1" oval skew. I suppose I am reshaping the profile that came with the skew; this is the first time I have sharpened it.  Anyway, I grind and grind and am left with a small portion on the heel of the skew that is not touched.  I keep refreshing the wheel with the SP-650, but it does little to speed the process.  The finish is really fine, hardly any scratches, even after refreshing.  I am beginning to think the Tormek is too slow to use, except when sparpening a slightly dull edge.

If I understand you correctly the plate on the jig would be square and offset down 1/2 the thickness of the chisel.  then the chisel would be held on the plate at a 30 degree angle from the axis of the wheel and ground.

I suppose one could just set the plate to get a 30 degree bevel and use it as a grinding rest, plunging it (not literally) into the wheel, not sliding it side to side.

I just bought a T-7 and proceeded to sharpen all my chisels.  I ran into a problem with a 1/2" mortising chisel.   It would barely fit into the square edge jig, not enough protrusion to get the desired 30 degree angle.  Is there a jig recommended for larger mortising chisels.  I was able to sharpen my 1/4" and 3/8"; the 3/8" stuck through just enough to get the angle.
