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?
Crazy!
every time someone remixes tears for fears, i remember dead race car drivers, that one kid with the cancer, bad cop shows, peta advertisements and now glass lathes. what is wrong with me?
really sweet machine. i wonder if they can spread the beam and blow stuff or if it's just good for seals?
Did you ever end up doing this? When I read this post...mind = blown. You're friend is a both a genius, and a revolutionary.Quote:

He's an engineer and crazy smart. I use to copy his homework in science class. Hiding wires and batteries has been the biggest struggle. I want it to appear wireless.
a good friend of mine nearly blinded himself with a laser pointer, shooting it into this quartz crystal while he was shrooming.
make sure you don't make it look TOO cool..
Sure lets talk about lasers.
1) You can spread the beam but you still have the same amount of energy. So spreading to beam is only spreading the same amount of energy over a wider area. Say focused laser can head a 1 square mm point to 1000°F OR that laser can heat a 4 square mm point to 250°F. To heat something 4 times the size to the same temperature you would need to increase the energy output by 4 times. (This is all approximate and there are losses and other elements at play here)
2) If a laser is bright enough to burn something, the reflected light it powerful enough to damage unprotected eyes. So please be careful. You can read up on powerful handheld lasers at candlepowerforums.com. There are several thread on eye protection and eye damage.
For some reason, this post gave me an idea. What about an e-nail type device, that used a laser to heat the nail instead of a metal coil? So the laser in a fixed position as opposed to handheld/wireless.Quote:

Wow, I guess I missed this one the first go around...nice stuff.
Other practical application: non-atmospheric or controlled-atmospheric glass welding. All the new "technical" glass being made now, some of it's bound to have limits as to what you can do with a flame due to the presence of oxygen, hydrogen, and possibly carbon. You could even operate in a vacuum -zero G or not, that opens the door for a ton of special applications.
I'm pretty sure Arnold Gruppe (Herbert Arnold) is making these because of demand - or banking on the formation of demand very soon.
I need to cut tubing with a laser. Any ideas on where a laser could be acquired for this task and what wattage I need to cut 25x 4 mil tube? or is there a better cleaner way to cut tubing?
I'm assuming this is a joke, but the P1040 Lazer in the video Trevor posted has information listed on this PDF: http://www.saengvith2000.com/5.Laser.pdf There is also contact information / specifications of the machines there as well if you wanted to purchase one.Quote:

So yea I'd cut tubing with your torch, or jaws tool / cold shock method. (Make a cut with carbide blade, put a little drop of water on it, then touch a soupy hot punty to that score and it will create a perfect crack along your score line and crack the tube.)
Yea, lasers are pretty spendy.
