Think i won't be asking anymore questions on here anyways.
You always seem to get your "head bitten off" after asking questions,
But when you answer back, its like being told off by the school principal LOL.

40-50 psi?, it would dribble out the end of the barrel lol, we are talking golf balls here remember? :lol: And you clearly don't have the first clue of what you're talking about. First you want to put "HPA" into a bug sprayer. FWIW: "HPA" is loosely defined but I've *NEVER* heard anyone use it to d...

Was it sc...

I don't think HPA is really the word to use here, that bottle is probably not safe beyond 40-50 psi. Wyz makes one on youtube with a soft drink bottle. How much pressure he uses i don't know, as he doesn't mention it on the video. Be around 150 psi at least wouldn't it? This spray bottle is a lot s...

True True, i was thinking it wouldn't be to bad as it would be a small chamber therefore not to much effort to pump it, but a bigger chamber or using co2 would be better. Using a butterfly valve would suffice to use it for multiple shots hmm design rethink i think ;P Thanks Jonesy :) No worries, ma...

Hey JSR, i know this is an old thread, but do you know what the inside diameter of the 1/4 copper tubing used on this rifle is?...Im guessing around 6.05mm. If I'm not mistaken this is for steel BBs, and you can get copper tubing in 1/4" OD, 4.5mm ID (steel BBs are 4.4mm). Yeah right, i forgot its ...

You have achieved the holy grail of *dakka dakka dakka*, congratulations :) What's the diameter of the tube before the inlet? if it's around 9mm, that's a recipe for jams - ideally it should be a factor of 1.5 times the ammunition diameter, so in your case 6.75mm or so - any chance of adding an int...

[quote="MrCrowley"]Wax is reasonably light so if you shaped the wax in to a more aerodynamic shape with the ball bearing as the front of the projectile, you probably could get better accuracy than just shooting a ball bearing. Now that all depends on things like range, weight and performance. But at...
