Hi Jake, you PM'd me but didn't say which laser you were wanting info on....My one is not a dorcy it is a DX. There is so much info on this forum about how to build a burning laser, it will take some time to read up on the subject but the basics are as follows:.
Buy a laser diode and aixiz housing from SenKat http://www.stonetek.org/
(he will do you an assembled unit if you ask)
Buy yourself a dorcy torch (I think SenKat can sell you one of those as well)
