I would think that an endcap with a hole can handle less pressure than a proper reducer and is less safe.

depends on what type of material he is using, how he decides to affix it and what pressures he is using, none of witch is listed,,

the brass end cap on my mini handles 400psi so i think that ...

an end cap in the nominated size..

lol i think we have all been there!!!

yes epoxy works good and of course pvc and metal can connect together ,just make sure when screwing the fittings together not to cross thread the pvc fittings,use a thin layer of teflon at the bottom of the thread and work your way up making it thicker at the top... 8)

not exactly pvc, but does this help...?

yea ive seen that one, still a little confused, will probably just go for it and see how it turns out, one thing i really like is my option to take the sprinkler valve apart if i need to, it seems like once you seal up a piston valve its stuck that way

go for it dude,its trial and error and when ...

Or you could just use a 3/4 nipple or 3/4 by 1/2" nipple depending on what size barrel you want to use. then find a kinco nut and olive to suit the barrel size and your away, with the compression fitting you can adjust the dept of the pipe extending into the tee

just a bit of an update i decided to mount my mini coax to the underside of my slightly larger coax,lol

ive also built a mini push button to depress the shrader, made from a chrome valve cap,spring and a brass nut/bolt

now its double the fun :D what do you think?

also a quick vid to show they ...

interesting,but like mentioned in other threads,i think you will have extreme difficulty trying to depress the bolt at higher pressures,maybe a leverage system should be in place..!!

Well considering jsr had the balls to admit to a failure i guess ill share my own failure, basically stupidity rather than pushing the limits of the device.

i wanted to basically create a similar device that i posted,a mini coaxial but a servicable one,its made from an oxygen flashback arrestor,and ...

considering propane expands faster than butane,id stick with propane

edit: try looking for mapp gas ,thats even better

And what on earth is jsr's failure cannon,maybe a link will clear things up..

as for performance now that the glue has dryed, is very impressive and alot louder than i thort it would be,but considering i shoot it at about 350-400psi that comes to be expected.

no real power test have been done ...

WICKED SNIPER ,it looks real enuff..

i take it that scope from hong kong never arrived?

i dont think he wants a projectile, he wants to blow high pressure air at a can sounds like fun,lol

well that depends on how its manufactured ,i used the same sorta desigh as above and mine didnt move at all.. and you will get better flow with 2 prongs
