Umm,,,, put a ball valve on the mag?? fill mag.... close valve.... attatch mag... open valve. Would that work? Still, i have no idea how you would fill it.... EDIT: Got it.... the end cap on the mag could be threaded.... and have the spring/plunger attach to it... So, you fill it from the back. see,...

UHMW the oil filled stuff, actually sucks. I used it as a plug once, but the problem with it is that its to soft. It dose not really "break" just kinda dents and bends and twists. and from my experiments, it wont hold threads worth a darn. Not to good for a piston... use pine.. or some of Mcmaster's...

It seems to only blow after the valve is opened at over 300 psi. i mean... it holds 300 psi fine... but when i dump the air it destroys the schrader valve... any sugge...

Okay... cone like velocity stack? as is... have a slow chamfer from the port into the barrel? I was thinking about filing the port all the way to the barrel with weld, and then using a chamfered drill bit to make a velocity stack... how much of an improvement could i expect from something like that?...

Alright. thank you for the info. :) Now, i am going to google this.... but a PCP gun has an air piston?? how in the world does that work?? TO GOOGLE!!!!!! So from what i understand.... and air piston is a secondary piston that litterally shoves the air behind the projectile... So valve piston fires....

Until you have reliable evidence that you actually achieved that velocity, it is perfectly reasonable for us to argue against your claim, simply based on the reliability of previous claims of that velocity. So, what your telling me is that gasses wil not expand faster than there SOS? The hotter the...

Here it is. my new baby. This is a high pressure gun that i am building/using to test my new fridge compressor. Does any one know what kind of pressure brass 1'' nipple will hold?? (my weakest fitting) Is it a 1'' steel piston valve, wiht 3/4'' porting (Does this qualify as a QEV??) The chamber is s...

Well... i got tired of not being able to find my fitting...So i made one. I have limited access to a lathe and a mill, so i bought a 1-3/4 hex bushing, and a 3/4 npt tap, and simply faced off the back of the bushing... and ran the tap in through the back... whole process took about 5 minuet, and wor...

hahah i agree.

And to be totally honest, the absolute best nerf gun you can make is a lung powered blow gun made from a 1/2''x''4' piece of PVC, or 1/2 copper... for home made darts.
