Since I'm a machinist, the answer is, of course I can. Most of my screws are for fat ice, very few for thin stuff like Desperado in Camden. I figure cutting to 4-5" (10-12cm) and regrinding the teeth and gullets. The only question is the thickness of the wall. It is actually thicker and stronger near the crank, so the screw will theoretically be stronger. Anyone have experience in this...having a thicker tooth at the cutting end. I could always just buy shorties, but have too many 22's.
