I finally got around to building a 2 brick forge the other day and quickly realized that it's going to take a long time to forge a blade with it. It just take a long time to heat anything up. Luckily we had a large trash pickup day this week and while I was out running I noticed my neighbor was throwing out an old propane tank. Needless to say, it's now sitting at my house. Does anybody have plans for building a gas forge from a tank like this (preferably with pictures)?

Try Zoeller forge (http://www.zoellerforge.com/) for some ideas.

The issue with your 2 brick forge isn't the forge chamber size, but the heat source. A single propane hobby torch isn't going to do much; two would make a difference (I use 2 in my 1 brick miniforge) but still may be too low/slow of a heat for you. Use a Mapp torch (or two) for more heat and you'll be happy. Make a 1/2" burner though and you'll likely get up to welding heat pretty quick (and destroy those bricks pretty quick too) :)
The Zoeller forge site is a good reference.

I did consider switching to Mapp, Jeremy. Only problem is, by the time I buy the Mapp torch and a couple of canisters of gas I could have bought many of the parts for building a large forge. Of course, right now I don't have any plans to build massive blades but one day I might.
I dunno, it's something to consider as the brick forge certainly does fit in the limited space I have right now.
Thanks for the suggestion guys, I'll check that one out.

If you can find a Bernzomatic JTH7 high temp torch it will get plenty hot enough for your 2 brick forge. I ran one of those in a 1 brick forge until I got an oven and real forge.

Thanks for the suggestion. There's an Airgas store a half mile from my office, maybe I can find one there.
