Sharpening the chisel with SJ

(1/3) > >>

SHARPCO:
Following is a general method for sharpening chisels with Tormek.

SG(#220) -> SG(#1000) -> Leather wheel.

But I want to do it with SJ wheel instead leather wheel.

In this case, how can I remove the burr of a flat side?

Side of the wheel?  (Maybe with the machine off?)   :-\

I'm of the belief that flat sides that need to stay flat, should be done on something flat, (if there's a chance it'll change the angle).

(p.s. Haven't tried... just an idea).

Good question.

If you are very careful, you should be able to use the leather honngwheel. To be successful requires care and skill.

I learned another method from Ernie Conover which may work better, especially for those who are unsure of their skill with the leather honing wheel. Leave the chisel in the jig and set the angle with the leather honing wheel. Use the leather honing wheel to polish the bevel

With the chisel still in the jig, remove the jig from the support bar. I keep a small very fine ceramic bench stone with my Tormek. Turn the chisel over and rest the back on the ceramic stone. Touch the middle of the chisel lightly against the ceramic stone and then lower the angle until the chisel rests evenly on the stone. Rub it a few strokes. Then go back and forth between the bevel on the leather wheel with the chisel still in the jig and the chisel flat on the back.

This procedure is only a bit slower, but is very controlled. The ceramic stone should remain flatter than a water stone.

I can't use the side of the stone because I've drawn the angle on the side of the stone for freehand knife sharpening.

How about using the paper wheel?
