DBC (Just Throw It In the Bag)

Duffel Bag Combustion
I've had this made for quite some time, it was just igniter and fan-less. Figured I'd fix it up real quick this weekend and get it shooting for tomorrow.
It's just your standard combustion that's been made collapsible. A lot of credit goes to Gort's travel combustion, I basically just added another thread-on barrel segment.
I also added a camping fan and lantern igniter. Fueling is done by cracking the cap and hosing in propane/air with a torch.
Specs
3x15" chamber
1.5 SDR-21x36" barrel
Fuel: propane/butane
Right before I took these pictures one of the fan blades fell off. I designed it to where the fan would fold up and stick into the back of the barrel, but one of the blades likes to come off if it's done roughly. I also rigged the wire at the back up because the back cover is a little too tight and is scratching the insulation off the back of one of the batteries, and then pressing the negative side and the uncovered positive "terminal". The blade(s) aren't moving in this picture because they're jammed into the back of the barrel. That's it! Still working on my other project at the moment, just took a little time out to finish this one.
