well... it's taken me a little less than a week, but I finally got around to painting my combustion. I was a bit worried since I've never really painted anything before, much less PVC, but I think it turned out decently... and while dismantling my gun, I thought it might not be a bad idea to start improving on some of the weaker points of my design (other than the aesthetics)... To make this shorter than my last post, I'll simply list out the changes made.

Paintjob (duh)
Custom NFPA and Propane warnings
Bigger fan battery housing (12v instead of 9v)
Wired in another spark gap
Wrapped meter pipe in Electrical tape (ran out of black paint)
Added shoulder strap (makes shooting a lot easier)

here's what it looked like before the changes:

Very sweet gun you have there! I'd have to say the part I love the most about it is the warning hazard diamond thing (forget what it's called, so whatever).

That cannon is beast! I love the paint job! How did you attatch the torch head to your hose?

well, I was at this plumbing supply place buying my pressure gauge and I happened to have the torch head for my propane tank with me and showed it to the guy who worked there and he said that he could just cut the tip off the torch head and weld it to the "T" connector which the hose and gauge are attached to... and it actually worked out pretty nicely, and he did it for free too!

...damn... it was a good cannon before, with OK aesthetics... but the paintjob and stickers really sent it over the top! It looks amazing now! Have fun with that beast.

thanks for all the positive feedback guys! I'll have to admit, it's pretty amazing the difference that $8 in paint can make :D and as I have some free time on my hands today I'll finally be able to test it out a bit and see if the extra spark gap and faster spinning fan help performance much, and maybe I'll post up some damage pics if i can find something suitable to destroy...
