Thanks. I think Im done with lasers though..As cool as they are, I lack the mechanical inclination/ability to adequately channel my creativity. Since before I have even joined this site, I had visions of these cool Steampunk style 405nm lasers that I want to build, but I just don't have the means or patience. So bleh. Will probably try and sell whatever parts and safety gear I have left up on the trading post. Take it easy, mate.
