Oops, that was supposed to say it WAS shooting a max shot of 310 yards, not 410. About a 100 yard increase in max distance after all the leaks were all sealed. And no, this is a metered MAPP gas combustion.

Yeah, I got all my leaks sealed up and performance is WAY up. By way up I mean it was shooting a max shot of 410 yards, yes I measured. Now with all the leaks and things cleaned and sealed up, it's shooting a massive 412 yard max, again, measured with the same tool, wind (being a barely noticable ...

I decided to go with the pipe dope b/c of the fact that both threaded pieces are damaged to the point that i would need a LOT of teflon tape to fill the gap.

Thanks Tallahassee, that's the answer I was lookin for. I did a little searching for something like that a never really found a better answer than plumbers putty, which isn't great against heat.
Thanks again!

The problem is that the damage is severe enough now that just teflon won't be enough to completely seal the larger gap... I'll try to get pics of the whole gun and the damages up tomorrow sometime.

The hose clamps were just part of my build. As far as the damage went, the gap in the threads (b/c I didn't screw them in tight) allowed some of the hot gas to rush past the threads. The MAPP burns at about 5000 °F, give or take 750 °F depending on the exact fuel/air mix. So after 3 dozen spuds ...

Well... I actually didn't screw in the barrel in all the way before I secured my hose clamps :? . So what happened was that the threads weren't tight enough to make a good seal. This allowed the hot gas to get through and cause heat damage to the threads. And no, no teflon here. It'd be almost ...

Hey everyone, I'm new here and have a few questions I couldn't find answers to right off hand. So. My newest setup is a 7.5 ft. MAPP gas monster. It's a 12" chamber with a U-Turn into a 7' X 1.5" barrel. I decided to go with a flyback transformer ignition circuit for reliability and I wanted to have ...
