I'm Chris in Fort Worth. I registered here to see the pics and attachments better on this site as I research. I'm a 52 year old welder/art maker, obsessive compulsive, perfectionist type of guy. I'm a firearm collector, shooter, and ammunition handloader, so yes, I take safety precautions seriously. A work buddy has been collecting a bunch of LED flashlights lately and another co-worker brought in a blue laser that he borrowed from a neighbor to show off. It is flashlight sized and very bright. It caught a sheet of yellow legal pad notebook paper on fire in about a second or two. I don't know exactly what model it is, but it has a blue sticker on it that says 5000mw 450nm and I saw one just like it on LaserPointerPro for $139. It sparked my curiosity, the reserch began, and I've been lurking here for weeks. Now, I want a hot little pocket burner. The Sanwu Challenger 2 or the Silver has my attention as well. I'm also interested in building one or two. I'm starting to feel about $500 trying to squirm away as I stand on this cliff edge. Or maybe, I'll just come to my senses and forget about it. I really appreciate all the knowledge you guys provide here.
