A simple forge on a cart. It can be left open at both ends or plug up the back hole for a hot box. This cost me less than $50.

My forge was around $80. The only parts I bought was the enclosure, control valve & blower

That looks like a hard worker too.
There's nothing like the right tool for the job - especially if the price is right.

Hey, Gene, where'd you find all the parts for this thing, and -- I may have missed this -- are you using a power hammer or manual?

Tom, I use a press.(Old tube bender from a muffler shop)
12" pipe, brake rotor off an old Lincoln Cont.,angle iron from old bed rails discarded,a tail pipe,ect...
One man's junk is another man's treasure.
I'm always picking up something.
It embarrasses my girls for me to stop the truck and go thru trash piles on the roadside.MORE TREASURE!!!

Kind of reminds me of someone...:)
