More progress tonight.
Sectioned the tank and welded up the front foot bracket. The tank was pretty clean inside with min, rust. Nothing that the grinder and a good burn out will take care of.
Finished converting the back of the fire box from a single 6 inch round opening that was somewhat blocked off to having a nice 4x14 inch opening that will feed under the reverse flow plate.
The interior view of the firebox now. Loads of smoke and heat should flow right into the cooking tank and under the reverse flow plate.
The feet and brackets have been removed along with the blower fan from the bottom. Will need to figure out where to mount the blower fan again later when we build the warming box.
Next up. Adding the framing to the trailer, widening the fenders for the mag wheels, and installing the tank for an initial balance of the whole thing. Getting there slowly but surely.
