Got my forge up and running- thanks for the help!

Hello all,
After a largish amount of scrounging and a bit of fabrication, I got my forge fired up for the first time this morning after work. Took a
little mucking around to get it set decently, but it's a hot little sucker.
Can't make any claims regarding it's ability to do things like welding, because I don't know what to look for in that, but it got about 12 inches of A36 to a nice bright yellow-orange in a few minutes, and I figure that's good enough for messing around until I know a little more about what I'm doing. Definately an upgrade from the propane hand torch!
Only modifications from Pete S.'s site were to add a steel back lined with kaowool and a 4" round pass-through near the bottom, and to use a 0-60 psi high pressure regulator instead of the 0-20 psi one. I figured I can always turn it down, so there wasn't too much reason to cap the upper end to 20 psi.
A note for those who use this plan, though- it's a real pain (at least in my local hardware stores) to find a propane line that will go from a 9/16" LH regulator to a 1/4" brass pipe. I had to use three extra adapters to get everything connected- a 9/16" LH male -> throwaway tank female adaper, a 1/4" male -> throwaway tank male adaper, and a 1/4" pipe coupling. Those 1/4" adapters must have been more common on older stuff, because they were really hard to find- took four hardware stores and a propane dealership to get that far, and the last hardware store had them in dusty beat-up packages behind a bunch of other stuff.
But there is (obviously) a question here- I have the burner coming into the forge body about halfway down it's length, and the flames come almost straight out the front from that point. Is there any passive way (like drilling a hole in the back near the top) to convince some of that heat to move towards the back as well? I'll keep playing with it to get it tuned up just right, but suggestions are very welcome.

When you think burner think straight line. Even if your forge has a square fire box the flame doesn't hit the wall and stay there. You will find that the flame flows in a vortex.
My recommendation is that you angle your burner backward. If you can this will make the vortex travel around the fire box and travel toward the back, the vortex will spiral.

Great to hear, Prometheus. I hope your forge brings you lots of fun and interest.

The steel back is what is causing the back end to be cool. That's why most of us just use moveable bricks back there. Getting proper propane plumbing: I got my propane-to-acetylene connections at my friendly welding supplier. My Propane supplier at the time helped, too. Not all propane suppliers have a good "back room" for this kind of stuff.

Gotcha. Well, it's served its purpose (namely, as something to hold the rolled steel in the right shape for welding) so I can cut it off now with no worries. I might try angling the burner back a little first, to see if I can get it work as is, but cutting it off won't be an issue if it doesn't.

You're not kidding there- the one I checked with had nothing to offer. I'm sure they sell fine propane and tanks, but as far as fittings went, they had nothing. Not sure where the local welding supplier is, as I haven't gone so far as to ever purchase a welder (there's always a good assortment at work.) If I need to do this again in the future, I'll probably try and find out where the local welding supplier is and check there first...
