barrel sealing piston gun. Gen. 2, sniper variant

[to_live]

that is an insane looking gun!!! i really do like it alot! but i dont understand how the "backwars barrel sealer" works could someone please explain to me how it works! with a diagram maybe? im kind of new to spudgun's

[jackssmirkingrevenge]

You mean like one where the projectile is actually resting against the piston valve?

Amen to that brother, barrel sealing coaxials forever!





edit: what pressure are you using? that setup looks like it could easily take 300 psi+, I recommend you invest in a shock pump to fullfill your design´s performance potential.

I have pumped my small copper gun up to 300 plus with my homemade high pressure pump but I admit that I am just slightly nervous about the blowgun at that pressure. Particularly since the gun forms the handle of the pump and the regular handle forms the footrest.
I can actually vent it with a schrader so I think I'll hook up a trigger to depress the valve stem instead. They are rated far higher.
edit: It doesn't actually fill through the schrader as well. I'm not going to take apart a trigger system every time I want to fill it.

[jackssmirkingrevenge]

IIRC schrader valves are good for 900 psi. So far I've only ever used schrader valves to actuate my exhaust valve designs, up to the 1 inch piston in my 3/4" cal launcher.

Very nice gun indeed!

I draw my diagrams with a black pen on paper, scan them as lineart and then tart them up with paintbrush.

this gun is like tottally amazing to me...idk why but it inspired me ... if u looked in my recent posts i have plans for a new gun i am going to build...just wanted to let u know that this inspired me

[Wash Burn]

lol lol !!!!!!! What a nice gun!!!!!!! where did you get that chamber???

[iPaintball]

That cannon is pretty sweet. I think the main reason I like it is because it looks almost exactly like a paintball marker. Keep up the good work!

I also have a couple of soda stream C02 but do you need a retarder or something to make it less strong?? Or can i just hook it up with some Orings and screw on? (Sounds a bit dodgy!)

my blowgun held 320psi for an hour with no pressure drop

i got one aswell man, if its got co2 in it dont f*ck with it. if its empty get some fittings and thread sealant and bolt it on, thos things are rated pretty high

welcome to spudfiles btw.

EDIT: for the above post; those blowguns have been used at excess of 400psi.
