    If you were hoping to click on this thread and get some truck tech, this is not the place :flipoff2:. On the contrary, this thread may give you some ideas for your next grill fabrication project.

    So the story begins, where all stories begin - I've gotten tired of the shoddy products available nowadays and I didn't want to spend my money on something that would only reliably work for a year or two. The goal for the project is a propane / charcoal hybrid grill that may be able to serve as a halfway decent smoker. I'm trying to do this thing on the cheap with the only new parts related to the propane burners.

    This thing started it's life as an air compressor (~ 50 gal) and will end its life cooking food:

    Went with greaseable bullet hinges left over from a previous smoker build:

    The next step which is kind of a bitch is building the flanges for the door. Stole these ideas from others, but they work well. The way that I affixed the flange to the door is by grinding slots in the door, clamping the flange, and then filling the slot with weld. This keeps the grinding work to a minimum, does not interfere with the door closing, and keeps the front of the door clean.

    To mount the flange on the vertical (rounded side of the door), get all the c-clamps you can find and start bending. The flange is 1/8" flat stock, so it bends relatively easily.

    And the finished flanged door. I've had pretty good luck running a bead of high temp RTV as a sealer along the flange.

    Never seen a grill with the ends missing. Is that to let more air in or let the smoke out when you’re grilling. :grinpimp:

    You got me thinking, and I figured I’d have at least one design flaw :idea:

    Nope, a snorkel - I heard they add at least 15hp.

    Put the divider in. Left side will be propane, right will be charcoal.

    Here is the burner assembly. Ordered the Venturi and valve online and will piece together the rest. The black iron pipe will be the burner after it gets a bunch of holes drilled in it.

    Not a ton of progress but checking things off. Ran out of gas and switched back to flux - damn it sucks.

    Charcoal basket and cooking grate.

    Sure, but not with this thing - we'd need a fork lift to get it on and off the trailer. I have been toying around with the idea of a trailer hitch mounted grill just for those types of occasions - might have to put that one in the que. We'll talk.
