This smoker has a Propane burner mod, but was manufactured for charcoal fuel...the pics to follow look crusty, 'cuase the metal has been pre-used in this smoker for 6 months.
I used the ash pan from the cook chamber for part of the sheet metal, and a couple of steel baking sheet pans for the rest.
I put a fire grate in from my old Brinkmann gas grill to support the sheeting so that warpage and sagging should be minimized.
This is the first piece on the fire box end, fitted and ready to secure:
The first section is started and the second (sheet pan) is trimmed and ready tie-in:
A look from the front at the grate and the sheeting:
The first joint of sheets is near finished:
The right hand end...had a piece of ash pan towards the front and a medium baking sheet towards the rear...tieing it all to the grate:
I had to roll my sleeves up and get dirty while I reached in under the grate to feel my way to stab the last 1/3 of the wires from the pan/grate tie-downs:
Forgot pics of the finished...it's a pretty fit on all three sides, with a 1" gap on the vent end of the smoker. I drill a series of staggered holes in the sheeting, less on the firebox end/center, and more on the vent end and towards the edges.
Temp testing on the gates and mid level reveals that I came out too cool on the vent end (40* cooler on the racks, and 25* cooler at mid-level...more holes to drill when I figure out the placement.
Cover End-Seals...the edge of the charcoal grate:
Used a Vice_Grip to hold the metal in position for drilling:
Rest of pics in following post...
