Looks good. I like the setup. Some paint would finish the job. Could you show us a picture of the vortex block? Thanks, for the comment (vortex block pics as soon as i take it apart.) Actually.... i have a c02 tank.... and fits into 2'' pvc... so i am going to totally redo the bottom half of the gu...

I was looking around in my shop, and decided that i had all the parts to build a vortex block BBMG. I was right. :lol: Here is the product of about 15 minuets of pvc work.... and about 1hr of lexan work, SPECS: Full hole lexan vortex block 6mm aluminum barrel, 12 in long... i think? ( i need a longe...

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...

I cant wait to see it. So, now i have another problem. MY schrader valve keeps blowing out... ive been through 3 in the last 2 days. 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...

wow that is a very small chamber and you say you can fit 150 psi :o my god thats fabulous .c to b ? huh lol well my sealing gasket doesn't seal up against the barrel surface part ... look for my post in the link below : D http://www.spudfiles.com/forums/self-closing-piston-valve-brass-fittings-t176...

The chamber in under the Tee. it is very small... due to the fact that i am using a .25'' diameter barrel, and need to keep a good C to B ratio What is wrong woth ur piston valve? i can probably help Pretty nice. A good name? The s.c.h.- small copper handgun. This gun does not have a single copper p...

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...

have you triedsuper glue? or maby this http://www.spudfiles.com/forums/making-epoxy-pistons-t8919.html Super glue? You think im smart enough to try something that simple?? I tried it, it worked. Thank you I feel like i have the intelligence level of a blueberry pop-tart. Thanks again kind sir

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...

This is like air gun porn.....
i love your work.

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.
