I convinced a friend of mine to purchase a tormek after my purchase of one.  Went to go teach him how to use it today and had a problem getting square edges.  I put his relatively new Sorby chisel in the guide, set it for 25 degrees, chisel was up against the stops and the stone has been trued.  Problem started when I when I started to notice that the sharpened edge was now angled a few degrees and not the nice crisp 90 degrees that I am used to.  Pulled out my Starrett square to check the jig and it look square.  Could the jig be defective or what?  I managed to fix the edge after about 30 minutes of eye balling it.  Didn't have the jig from my machine handy to compare.  Any thoughts on this one?

Most likely, it is a problem of the pressure applied to the two clamps.  In addition to aligning the edge of the tool to the pins on the right, it is also necessary to insure that the top and bottom of the clamp are parallel with each other.  Even small amounts of extra pressure on one clamp or the other will cause skewed edges.

One way to monitor and correct this is to check the grind shortly after starting the sharpening process.  If it is skewed, tighten the clamp on the long side and back off the clamp on the short side.  Very fine adjustments (1/8 to 1/4 turn) will have a big impact.

Grizz, you must have been typing this while I was typing mine.  If you're on e-mail notification, the answer is right above your post in the forum.
