Here is betty 1 i gave her a funny paint job to make it look less harmful
shes got an electric barbeque lighter it was about $20 and a home made propane rig.i made it out of a peice of 1 1/2 ft rubber hose a propane torch and some fittings its quite simple and it will mix air and fuel for better combustion it works way better that straight propane... the quick release is also an awesome safty feature.... if you have any questions just post

Wow, I love the Pastel colors, that's what makes the gun stand out.


As for the propane being hooked in the end cap, nice idea. Less holes pounded into the chamber, and the cap will hold up. I had my chamber fan mounted on the end cap so it has 2 holes drilled through it. Then again, it was bolted on both sides and teflon was there to prevent leaks.

Also, what is the gold thing on the cap, I can't really tell from the picture.
