Smallest torch? DIY?

I want to do some very fine detail work and am pondering making a simple internal mix torch to produce a flame no bigger than 1/8" diameter, preferably smaller. Though I love my Bullet Burner dearly,...

I "own" my tanks, but it's actually something like a 99 year lease. When empty, the gas place just does an exchange and I never have to worry about hydrostatic testing. There are good reasons to get...

IMO, arresters should still be used because surface mix torches can fail internally and mix the gasses. It may be rare, but it's not unheard of. The Bethlehem advice is good- any surface mix torch...

I work mostly clear boro and find #5 too dark unless the area is very well lit. A couple of cheap reflector floods of at least 100W (CFL equivalent) is needed. You may also have an inability to focus...

That's a really small tank. I use a pair of Q tanks because I don't like moving the big ones. With a pair of them I can quickly swap them out and refill as necessary. I don't work very long sessions,...

Something else I'd worry about with outdoor storage is bugs making cocoons in various openings and plugging them up. Seems to happen to things around here.

Knight Bullet on small tanks at about 1000 feet. Boro doesn't stand a chance, fused quartz struggles for a bit, then gives up and melts.

I cheat. The welding shop sells thin tungsten electrodes that you'll never melt or burn. They do conduct heat like crazy, so you need a holder. I use a piece of stainless steel rod with a hole in the...

FWIW, I run a 1# bottle with my Knight Bullet. The regulator is a welding style that's been repurposed by changing the inlet fitting to a tank adapter so the whole mess screws right onto the 1#...

In the on-line photography world, "fine art photography" is usually a euphemism for nudes and soft porn. I know that probably isn't what they're after! The request for a "fine-craft element" is...

I had the same concern about how far the torch mounted arresters would stick out. It turned out to be a non-issue, but it depends on the torch and how intimate you like to be with it. There's a...
