I meant the chrono numbers. how do those stack up?


as for the valves...a 1.5" ported valve is a completely differnt monster....everything is smaller which = lower costs. (although the smaller diameter stuff can handle more pressure)

I just finished the cad files for the piston and back-cap, and I'll be sending them out for quotes this week. As soon as I get that info, I'll know. I'm 99.9% sure it will be under $100.

anyone know how those numbers stack up?

finished the new valve and did some chrono testing: Tank= 4" tubing x 3.5' long Barrel= 3" tubing x 5' long "shot"= tennis ball (wrapped with cloth to fit the 3 inch barrel) pressure= approx. 100 psi results (10 shot average) = with spring- 415 feet per second = 283MPH without spring- 460 feet per s...

I think he's referencing the initial post where the guy says he has designed paintball markers. It does seem a little strange that the initial test product blew up and looks rather crudely made. I guess most engineers don't stray too far from the drawing board. This may be why they return to it so ...

No, I design & manufacture parts for tourney/speedball markers.

Seal material and not revealing it. Hmm, looks like soft-core vinyl but that's just my opinion. Nice looking though, minus the cracks and stains. My question is what would make us purchase yours over say the Mauler? Oh, and I'm 29, have a chronometer, a good bit of experience, am a business owner a...

I know, the glue-job is messy, but its a prototype. don't even think about asking ask what the seal material is, you wont get an answer. You can see how the back cap shattered at the screw points. However, I just figured out it was really my fault...only had 1/2 the screws in....was in too much of a...

WOOHOO>>>>YIKES ok, so I intentionally overpressurized the valve......at around 250psi the back cap failed...BANG!!!! the pvc shattered at each of screw points. and it shot off like a big plastic bullet. The 3" T however appears fine and held up great. I was filling from the back cap (using the exha...

on that note, anyone know how to post pics?
