OK. I guess this means JoeyB owes smallblock a bag of donuts. I still want my bag of money.
I never use compressed air to clean a lathe or mill. It blows the chips into areas where they can cause excessive wear. Also, if the air pressure is too high, the chips can embed in an eye if you aren't wearing side shields. I use brushes and paper towels. It's slow but gets the job done.
