Couple old 30 gallon air tanks, some random pipe....5" schedule 80 for flue, 3 1/2" schedule 40 for combustion air.
Still need to get stuff for oil tank, and drip system....and decide which burner style I want to go with...
It looks like somebody's nightmare......but it's got character!!! LOL
I think I might redo it though......it's too dang tall!!!! I can barely get it out of the garage......and it weighs a ton!!!!
Maybe re cut, and remove about 6 or 7 inches out of the middle.
