Laptops have a 9month life expectancy. After that, they are usually not worth repairing. I have a 9600 M GS that died due to heat, what i can tell you is, that if any part of the laptop has suffered heat damage, it is VERY likely that other parts have suffered as well. You might replace the GPU, sim...

You keep using "green gas" and "propane" interchangeably, is green gas propane?

Ahh, I see now. I was confused. So it's like a hopper, feeding into a magazine. Seems like a decent idea to me. I might build a pistol with that concept... Edit: as for a use in this design, you were talking about a large"hopper" feeding into the bb chamber, possibly via a ballvale or something simi...

would that be correct?

Jack, I would love some more info on how that magazine works.
Possibly a diagram?

Do you get any jamming problems with a full load of BB's?. Sometimes, but not very often. and when it does jam, a little shake fixes it. sounds great :D , but if it fires 12 bbs every time, how is the accuracy? Its about as good as any other BBMG with a 4'' barrel. :-) i can hit a pop can from 25 f...

the rifle that jack linked you to worked very well.

I did notice however, the slide valve seemed harder to trigger at very high PSI, such as 350+ psi. A little bit of mineral oil seemed to help alot.

*video* KRISS bbmg pulsed cloud design.

This is my latest project, the body is based (loosely) off of the KRISS smg. SPECS: Firing pressure: 75 psi via pop off valve. Firing valve: 1/4'' QEV. Chamber: Co2 tank, used as air tank. This gun use a QEV modded for full auto, with a 75psi pop off valve, to pulse air from an old co2 tank, into a ...

I've never used metal bb's in a bbmg... But every time I build one with a detent, I always see shattered bb's

Jack, that's how I've always looked at it... A clear launcher and high speed footage would be fantastic. You could Order a foot of clear PVC on eBay pretty cheaply. @LnL. Do you have a detent? If so try it without the detent. See how that works. If not, I have the best luck with the air input being ...

Sorry, I meant cloud chamber, mine feeds horribly, I'm trying to use 850psi. 850 psi. My pop of valve opens at 65-70psi. So I'm sure you are dealing with a whole different set of parameters. How tight of a fit is your barrel? Ive found that clouds feed much much better with a very tight barrel. If ...

My chamber was 1/2" what size is yours? My chamber is a 1/4'' x 6'' pipe nipple. can you fire it aiming any direction? Yes. what psi are you using? clever trigger! this gun looks really nice, but if it shoots 2-3 bbs every time, is it accurate? heck no. Its a BBmg lol. the accuracy is actually dece...
