I have been looking into some air blast options but right now unless I want to roll my own the only option is the smart cool to the tune of 500 bucks. Granted I've spent probably more than that on failed cutter experiments in the last month but it's still a little bit of a pill to swallow. I know it would be relatively trivial to just fix a nozzle somewhere and attach it to my compressor so I might do that as an interim step
