I've actually ordered a new DC brushless pump and 12v mini SMPS for this laser. I also ordered a nice 11cm heat exchanger to fit a 12v brushless 10.5cm cooling fan I have. In addition I have a nice 100mm-FL 20mm-dia ZnSe focusing lens on the way from Laserlands.net. The pump and smps should arrive in a week, the heat exchanger is on backorder but should be here within two weeks, and the lens could take a month or so.
The only thing I'm missing from this CO2 rig is a nice case. I don't have the means to do any kind of woodworking or real assembly of building materials, but I do have an acryllic case which I made years ago for a bunch of concert flutes (when I was still a musician) that is sitting in my closet. It just has a hinged lid and the 5 sides are not squared or accurately cut (because my local hardware shop can't make a 90deg cut or adhere to 1/8" tolerances to save their lives), but I should be able to fit everything in it. The problem I had initially making it was that it would crack if you tried to drill it, so I had no way to punch holes in it. Now, with the CO2 laser I can finally punch holes in it!
EDIT: To my surprise the SMPS and pump came in the mail today! It is a 500L/hr pump.
