If it will work, I'll also try isopropyl alcohol too. It would be much less of an irritant.
Sounds like a plan, though. . .I've never heard of using denatured alcohol as a coolant before. In most cases, coolant is primarily used for washing chips out of the cutting area, will be interesting to see if/how well it works.
