Sounds cool, though keep to one plug. Just run your ejection system parallel to toaster circuit.

@tghhs 'I curse you!! you've been a very bad topic!!' :D lol relax the reason why no one responded is probably because most of us are not experts in fluid dynamics... In a typical piston valve this would help but in coaxials air has to do a 180 deg turn to get into the barrel and the other surface ...

@boyntonstu Not sure if we were posting at the same time (pretty sure we didn't) but please don't ignore my relevant post and change subjects to safety. I DON'T CARE HOW YOU LOAD YOUR GUN. I want to know if modifying a coaxial barrel with a flare can give better flow than a equivalent T-valve. EDIT:...

Hmmm how about some on topic discussion? hahaha, well Rag, To enhance the flow in my coaxial valves i flare the end. Doing this i hope to (just slightly) decrease the ratio of chamber to barrel, creating that 'snap' open when the chamber pressure hits the barrels surface area on the piston. I also b...

Yeah, that would make sense. I'm sorta thinking that maybe the barrel support could have slightly bent it out of shape, because it was quite a tight fit. Also, because of the pretty extreme valve seat to diameter ratio, the piston would have been putting much more force on the barrel than most canno...

ummm..... you broke a pvc chamber?? Did you use DWV fittings? (non pressure rated) Did you use the proper glue? PVC is very strong, and would not fail if you used pressure rated fittings and assembled it correct-ally. Pffft, PVC aint strong. actually, it's crap. http://www.spudfiles.com/forums/view...

Yes Gippeto I believe it was your drawing I modeled it after. Where do you recomend to place the bumper? Or should I just go with an O-ring bumper? Also, what is the easiest way to make O-ring grooves without a lathe or dremel? And that washer wasn't really drawn to scale, I try to find as big a wa...

The barrel was the weekest part

So i was out testing this launcher: http://www.spudfiles.com/forums/tghhs-ass-kicking-large-bore-t20207.html After i'd just given it a new chamber and barrel, because it had a tinny leak through the front bushing that was annoying me. I used pn9 for the barrel this time though. I took it up to 100 p...

yeh, though i'd have the barrel stopping just after the start of the 90 degree part. Not in the middle of it.

As is, it creates more turbulence and less flow.
