Heat Treat Rig.

I have a plug welded to one end. The wood/charcoal goes in the pipe to wards the rear.

Tai, is the wood or charcoal placed in the forge or in the pipe? Could one end of the pipe be welded instead of the fiber blanket?

Yes, the wood is placed inside the muffle towards the rear closed end, to create a reducing atmosphere inside and shield the steel from oxygen. Wood works better than charcoal, but charcoal will help a little.

The pipe can be welded or folded over tightly on the end to seal it up.

Rick, How did you go about making and rigging up the thermocouple for your pipe?

Does anybody use muffles with vertical forced air type forges? I have a 12" diameter pipe with 2" of wool and two 4" square ports across from each other. The burner is a good 12-14" below my main working area and there is about 8" of open space above that. It's nice because the way the flame swirls I don't have any obvious hot spots in the working area at all, but I still have a hard time getting even heats for some reason.

Anyway... just curious... I've only heard of the folks with venturi type horizontal burners using muffles...

I saw a long tubular burner smaller then that with lot's of tiny holes running the length of it a Home Depot yesterday. It's to long and wide for my mini-forge and doesn't have any threaded connection but it's $15 , think its worthwhile to buy? There was only 2 left and I'll be building a better forge probably in a month or two . It was kinda oval shape and long with a crimped end maybe 2" to 2 1/2 "wide and 14-16 " long .
