Joe has done a lot of welding Razz and great quality at that but for this "small job" I was hoping to find someone a little closer

Saw this on Colin's site about heater boxes and welding them up.

While I am at it..rehabbing engine tin, and patching heaterboxes.

I am miles from my miller mig welder,and oxy acetylene.

Thinking about soldering patches on heater boxes?mig left gaps which eventually held moisture,then rotted. So,Real metal,flux,solder,
propane torch,as I have yet to buy that roof coppering electric iron...
Probably will work better...Any thoughts?

Tough environment for metal. Hot hot exhaust meets cold cold rain splash. Fractures aplenty. The jackets are normally just pressed over the exhaust with crimp seams that allow the temperature extremes and vibration to let the jackets give a little. The jackets do not need to be airtight, they need only a robust supply of fresh air from the fan(s) to give you decent heat.
