Some specs:
Chamber:
Comprised of 4 4" couplers, 4" cleanout adapter, 3x4" bushing, and 3" female adapter. (plus the various sections of pipe to slap it together) In HGDT, I enter the length as 14.4. It uses 3" bajo couplings to enable breach loading.
Barrel(s)
As of now, I have a 2.5"x48" barrel (C:B .8 ) which should be pretty fun with tennis balls. When the judge finished my 2" rifled barrel, I'll make it 72" (C:B .8 ) which should be pretty nasy with taters
Fueling/Ignition
As of now, I'm using propane. When this tank runs out, I'll switch to MAPP. My meter is 12" of 1/2" and I'm running 45psi. I have two gaps with the bbq ignitor, which is sexily tucked away in the 3/4" handle (notice the cut away coupler for somewhat of a safety. I currently have a single fan running of 18v, but I'll be adding a second smaller fan in the center of the chamber to hopefully induce turbulence.
Misc.
The "tank" with the switch holds spare batteries, and a tennis ball. Kinda cool. All my pipe clamps are sleeved in black vinyl hose. Very sexy. All thats left to do is get the clamps even. grrr...
When I finished up the meter, it was all systems go. My dad wanted to see this thing work. I stuffed a rag in the barrel, charged my chmaber, and clicked the ignitor.

Also pictured below are some old projects and "The Enforcer" which has been used for a few parts including the barrel.
Anyway, Rebel Yell is almost done with the exeption of the rebel flag stickers I'm waiting on, and to get the clmps even. Hopefully next weekend I'll get some damage pictures/videos.
Whatchyall think?
