I bought one of those 40 watt glass Chinese lasers off eBay in June 2007 and I still have not got it to work, I did not have instructions. I have asked the seller for instruction on how to do this but they have not responded. there are only 2 wires from the power supply but if I get them the wrong way I was told it could crack the glass. (DON'T WANT TO CHANCE IT) where to start. that is how I found this forum, can any one help!

I have built a box to house it which will enable me to mount it in the machine I have in mind.

does anyone know who I can call that will come out and set me up in Florida, I am willing to pay.
