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

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.

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!

Where did you get the CO2 thing at? i need to find me one.

~Jack, what do you draw your images in? they look kinda rough at the edges, like pencil, but that aint scanned. you have a original style. me likes

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

heh. neato!(needed something longer)

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

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

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.

cool gun what type of tank is that and will hpa work on it
