This is prototype #2, measuring 15" long, 12" tall and 8" wide. The inner chamber is 5" x 12.5". I've got one available, but should have more soon.


Here's a video of the forge at the hammer-in last August. You could hear a little spurt at the beginning. This stopped happening after about 10 minutes, although was prone to it when the wind blew a bit harder. After about 12 hours it started to run out of propane, but held up very nicely for the first and second day. Most of the time there were three people with metal in the forge, two in the front and one in the back. Not quite as hot as the dual burner whisper or Tracy's blown forge, but it was very nice and even with a very quick turnaround for forging. For what it's worth, I no-flux welded two san-mai billets in it and it welded fine.

TC showed 2300° F at the front and 2150° F at the rear, while running at 15-17 PSI producing about 80,000 BTU

Includes adjustable regulator and extended length 100K Graham Burner

I am without forge, and strongly considering grabbing this guy. I make knives primarily with the occasional sword experiment.

Regarding swords:
1) Is the hole in the rear capable of putting a blank (say 0.25" x 2") through? Or is it just for exhaust
2) For heat treat, would it be reasonable to get a 36" length sword to 1475F? Or will it cool too much while cycling it in/out
 
Three more available. Just let me know here then go purchase from the website.

Thanks

PS These now ship with 8" long burners, instead of the normal 6"
