SB15 doesn't believe in pressure guages on meters :wink:

I'd give it 5days before Tyler posts a very similar launcher :)

Nice, clean as usual, good sutff.

It's visually similar to my design but really not that similar; my chamber was serviceable via 6 large bolts in helical inserts, also utilized the bolts as part of the wiring system to avoid drilling holes in the chamber, and had a 5-gap spark strip. And yes, SP15's design along with Gort's were influences on my design.

The handles are the same design I used., and the general "layout" is the same but that's about as far as the similarities go. SpudBlaster's barrel support is superior to mine, and I might copy it if he doesn't mind...

I also couldn't find cam-locks but wanted to use them, as I mentioned in my thread. Nice job there.

The electronic wiring and gas metering system (do I see a mapp cylinder?) look great too, minus a pressure gauge.

SB15, excellent job :) Another great advanced combustion.

What did you paint it with? I like the flat black look. I went for glossy but I'm almost regretting it now.

Peace,
Pete Zaria.

does mapp have a great range of combustability than propane? I think propane is 2.4% to 9.2% or something, and I have a mini'ish combustion thats kinda finnicky on the ignition front. or at least that is what I think the problem is. In which case, using something with bigger range would help...

Love the breech load system. Anything that has a slide-through barrel support and cam-locks is awesome.

Hey I'm new to spudfiles and i'm looking for information regarding successful propane cannons. I'm concerned with getting a correct air to fuel mixture with propane. I have bought a lot of the propane metering parts already. Is there a certain length chamber and metering pipe that works very well? I am spending a lot of time and money on this project and I really want this cannon to be successful. Care to share any information or specifications for the metering of propane that have worked well for you?? I would greatly appreciate it. By the way that gun is wicked looking. Nice job!
