We will be interested to see how you aligned the mirrors. HM

+ rep for that video. Thanks HM

For smaller lasers, many cigar stores carry several sizes to choose from. HM

As usual, here in Iowa, the clouds move in just before a great celestial event and today was no different. The sun disappeared just as the event was starting. I guess we needed the rain............... HM

I'll use my electronic welding shields set to MAX. I looked at the sun yesterday and it's a ho-hum green ball. HM

As "Scotty" once said at a sci-fi gathering -- Man has developed many ways to disassemble a human body but no good ways to reassemble it again. HM

Ved - How will you concentrate that power from two flash tubes with an arc length of ~100 mm into an 8 mm long yag rod, part of which is for mounting? HM

That's a really short rod to utilize a straight flash tube. I too would opt for the 808 diode bar. HM

I got my refund from ebay about a week ago. HM

WOW- 1200 WATTS of 638 would be outta'site! How many Amps are needed? Can it be portable? :-) HM

I have a bunch of "dead soldiers" from the past. You need any ? :D HM

Benm -- I can dump ten bucks in a bar in a few hours. This might be a joke or better. "IF" it works, a couple galvos and TTL drivers might make a starting project. Otherwise, see my avatar. HM Ship Date: May 22

I ordered one for grins. The next day it was reported shipped. We shall see......... Looks like a take-out from a projo prototype. HM

Huh? Hm

Dans -- I don't recommend a laser of any wavelength. The reflectivity of the polished metal will likely cause dangerous and power robbing reflections. A pulsed laser will likely deliver a string of dots unless you scan slowly. HM

Glass blowing is an art like blacksmithing. You have to practice OFTEN. So many of these arts are dying because there isn't an "app" for it. HM

It is a constant voltage supply with limits on current and voltage. You can google that number. HM

Look at a PTH08T250 module for 40 Amps ! HM

Cut the holes with a plasma cutter. 20 Amps should work fine. HM

Wait 'till Flamin Pyro sees this. Although I'm a pyro, he will be of more help. Nice work.+rep HM
