"Weed burner and a cement mixer." I think that's a perfectly reasonable next step!
Ya, just your typical isometric done with a drafting machine. My grandaughter was very impressed with the drawing. :)
"So the handle part just rests on some type of support so you can pick it up and dump when ready?" Right. Just a simple bushing should do the trick.
"Another gear on the opposite side of the drum." That's what I'm doing. It's an idler sprocket, which is the third of the three-point support. The center of gravity is always between those three points, so it should spin OK.
Thanks for the picture, CMTWGR!
Here's the Sievert 294202 burner that's on the torch I have. Its specs: Burner diameter 32mm, Gas consumption, at 4 bar 2000g/h, Effect 26kW, Made of high quality brass.
Dan, how long of a flame does that sievert burner put out? I ask because I was wondering if it could be incorporated into your roast chamber on the opposite end from where you currently have it pictured, with the gas line inserted a bit loosely through the "handle" part of the roast chamber. (no solid connection to the end handle to avoid kinking the burner hose as the roast chamber turns.)
The end result being that the burner flame would be "shooting out" of the chamber instead of being directed in. However it would only be good if the flame produced by the burner was a short and not long as you wouldn't want the flame to exit out ot the roast chamber (bad). :(
The benefit of the above idea being that of a design incorporating the burner and roaster chamber as one integrated unit instead of a 2 separate things.
I took some liberties with the image you provided, just to illustrate my example indicated above:
Note that the image of the burner is of course inside the roaster drum and not outside the drum as it looks like in the picture. :eye-popping:
