They are good fun. The air assist helps reduce the charring on the cut edge in woods, as well as stopping flames.
I engraved some glass bottles for Xmas presents (www.benjaminalderson.com) on a friends laser - definitely needs an improved extraction system as even with a mask it got bit raspy on the throat :S
My laser I'd almost up and running - got power on/off to laser tube working, just need to sort out the power level selection now.

If Feds call you and say something bad on me, it may prove what I said are truth, they are afraid of it.
