Hey Ron,,, I have looked at those pics a dozen times so far. VERY NICE!!!!! I saw the tubes inside it, and thougth that was what they were for. I wanted to make a stove from round pipe, but the price to have the metal rolled was unbelievable. I build my entire stove for the price of the outside tank center,,, not counting the end caps. I checked at several steel distributors in WV. WV Steel in Charleston, WV wanted over $2000 for a piece rolled 48" in diameter, and 60" long. I don't have $2000 in the entire unit as you see in the pictures without the shed. I used 1/4" plate,,, Grade A36. I bought the 4 X 8 sheets of 1/4" for $275 a sheet. 5 sheets, plus some flat bar, angle, and box tubing, and HEY,,,, I got a stove! I bought my new mig welder just for the stove. I have a Lincoln Pro Mig 180. It's plenty hot enough, but the duty cycle is only 30%. You can't weld continually with it. It kicks the thermal switch. Next welder will be much bigger.
I'd be interested in seeing more pics of your sons stove, and some measurements as well. I hope to build a second one this summer, and his is a very impressive stove. I didn't know much of what I was doing when I built mine, but had already figured I would build a second one. I am a decent welder, and love working with my hands. I'm usually rebuilding a car or truck. If it weren't for my OWB, I would be working in a COLD garage right now.
A for the draft fan on the door, no problems so far. The motor is on the opposite side from where we get the rain, but I'm sure it gets it's share of water. I plan on putting a shield over it very soon.
