my new and first pneumatic rifle

[john bunsenburner]

Ok i first of all have to say that i am starting to notice my idea will most probably have to be compromized due to the fact that i am asking for the impossible(correct me if i am wrong!). Second of all i think the best way to some what make what i am asking for is to have a tank with air that i will call my Main tank and my chamber this will work exactly as Gippetto suggested. Further more i think that having a rather limited supply of tools, due to the fact that i have just moved houses and am still planning a nice working space for my self, will highly limit the possibilities i have. I think, from what i am understanding now, i will have to abandon the idea of portability, but not the several shots. To answer the question Gippeto asked i have acsess to a Metal fundry, the normal hand operated Tools including screwdrivers, hammers ect. ect., i have a good electric screw driver, a bench grinder, a home made Lathe, and lots of electric motors and other spacre parts you can get from dumps. I hope this helps in helping me, as seen in my other Post i am not quite sure of how Piston valve works or id built. I one again thank you all in advance for all your help and ideas, hope to get some replys soon

wow really?

I think you should use a QEV valve and malleable iron (lol that's what we call steel) fittings and pipes... a piston valve might be a bit too difficult for a first gun...

ohh and try to build a fridge compressor

[john bunsenburner]

The thing is there are no QEV valves here definately none under 100$(400 zloty!). i think i have piston valves figured out im unsure abot O-rings though, so im building my self a lathe. As soon as i find an old fridge ill make it a compressor and if not ill build a high powered piston compressor(high powed means about 200-300psi).

[POLAND_SPUD]

if you have relatives living in poland you can order a QEV on their adress...and then collect it when you visit them... you could have a 3/4" QEV for ~65 zl (shipping included)

[john bunsenburner]

how much better is it compared to a piston valve? also like price wise

[POLAND_SPUD]

A QEV valve is in fact a piston valve.. but it's an off the shelf part (not homemade) so you can expect it to be of higher quality...

1/2" and 3/4" QEVs cost only a little bit more than building homemade piston valves of the same size (well at least in poland).



I am trying to find a shop that shipps to switzerland... if I find one I'll PM you its adress

[john bunsenburner]

Ok thanks alot for that.

[Gippeto]

With a lathe and a foundry, you're set. You can make everything you need for a very good piston valved gun.

[john bunsenburner]

ok thank you all for you help, i guess i know what i have to do(and what not). Ill start building the gun as soon as possible.

p.s. do you think a dremel tool would be of any use to me? im thinking of buying one

[Floyd]

YESS!!! Get the dremel!! They are extremely usefull for just about everything. Cutting, grinding, sanding, routing. If you don't get the cheap kind you get a whole lot of accessories with it.

Especially if you are making the wooden stock. That will help a heck of a lot.

[john bunsenburner]

Yh i got it today for about 100$ and i have to say im very happy, it cut through a bar o steel like nothing and nearly burnt a piece of woad on the highest speed(now i noe wat not to do!). Im sure this will really help me!

Actually I've found a dremel tool, a bench disk sander, and a small drill press all immeasurably valuable especially using PVC in spud gun construction.

Yes, get one.

I can also vouch for the Dremel's use working with copper.

One word of advice - buy 3rd party unbranded tool sets, Dremel charge a fortune for theirs.

I got mine relatively cheep the shop was selling all their stuff at discount prizes.
