Soooo cool
How does that not bounce around everywhere?
very cool, thanks for sharing
it be a cool micro hand torch.. too bad its a giant co2 laser
A light saber style torch would be sick!
A geeky friend has been bugging me to make laser rigs. Instead of torches heating ti, a laser

I believe they can control the focul length of the laser. If I understand what you mean correctly.

Whoa! That is freaking awesome!
Focal length is controllable on CO2 lasers.

Is it cool? Yeah, it is. Is it practical? For 99% of stuff, I'm not too sure. It seems like technology for technology's sake, rather than to fulfill a real need.
It strikes me as a little like buying a Segway to go 100 feet across the street to your neighbor's house. Yeah, the Segway is cool. But just walking over there is a lot cheaper and easier. It's hard to see anything in the video that couldn't be done just as easily - and a lot cheaper - using a torch.
Yeah but I believe that opens the possibility to make objects in zero gravity.
I've seen instructables on using the laser out of an old DVD burner to make a paper laser cutter. Maybe you can focus it well enough to heat up the end of your nail?

awesome link thanks menty
that second video they cut the tube have it a perfect polished opening and then seal it back together in about a minute pretty impressive.
i imagine it would be used for the same reason they use lasers for welding aerospace stuff, theres a 0% margin for error if its something that has the potential to be extremely hazardous/expensive if it fails. a regular beaker like that it does seem ridiculously over complicated, but also the technology has to start somewhere. for those glass tubes that pipe liquid sodium i would rather trust a cnc laser lathe with a built in x-ray or whatever it is to make sure its a perfect weld.
i imagine the heat is extremely focused compared to a torch. resulting in a thin heat affected area?
Yep, I'd imagine. Might only work for quartz - could possibly just thermal shock chips off of boro - but probably high RPM on the glass and pulsing the laser could make it work for boro or higher COE.Quote:

Very cool! I am currently building a dual moving chuck, CNC Glass lathe sized similar to my Litton F Lathe. The Litton is just too slow in moving parts in and out. Nice machine, but I need 10-15 units to get the production requirements. Will mostly be making vials and inserts from borosilicate tubing. I also have 2 of the Keyence micrometers show in the video. Very well made stuff from both companies. Thanks for posting Trevor. Was curious if anyone had done a dual moving chuck before?
