Here's a grill were building for the rig from a 55 gallon drum.
Without the grill grate, the frame that supports the grill just sits in place. The inverted V shape angle will support a metal plate to help dispers the heat front to back. Got to pick it tomorrow from the metal shop, they will put a bend in it to match the V. Probably 12 ga thickness.
Here's the propane orafice in the iron cap, with 4, 1/4" holes, based on Joe's (boykjo) design.
Here's the cap in place, I've cut the burner pipe at a 45 deg rotated it 180 deg and rewelded so it points straight down. The flange holds it in place and I have a single bolt in the other side of the smoker holding the other end of the burner.
This is it all closed up. Yes, slight alignment issue with the lid. Something went wonky during construction. Very disappointed in it. Hope to get it straightened out.
Back side so you can see supports and hinge, just a 1/4" steel rod.
Bottom side showing supports and mounting base. Mount is still not complete. After the drum was cut in half it was very flimsy. This frame has stiffened it back up.
Hard to see, but I have blue flame!
Ran it the other night, for 30 minutes with the grate in it. Set a chunk of metal in the middle and cranked up the gas. Exterior surface temp at the top was 450. Directly under the burner it was 240. When I turned it off and opened it up the hunk of metal was 605! The burner was a dark red which I think is around 800. So far it's preformed really well, need to clean it out and throw some meat on it and see how she does!
This will mount in front of the smoker and slide out... Stay tuned!!!
