.177 Stick Gun (with Semi-Entertaining VID)

[VH_man]

well.......

I have been trying for quite a while now to construct a gun that uses no fittings and is somewhat a scaled up version of Jack's Pengun. Finally, i have suceeded.

The barrel of this gun is 12 inches of .25 OD .177 ID aluminum tubing i bought from my hobby store, and the chamber is a 12 inch length of 1/2 inch type L copper.

for a piston, I used a .3 inch section of 17/32 OD brass tubing filled with epoxy. the sealing face is a peice of sillocone stolen from a useless baking sheet thing and CA glued on the front.

As for Pilot and Fill, i used a Presta valve i stole from a Road bike Inner Tube. sadly, when i epoxied this in place it fell over during curing.........

so... without further Adue i give you the .177 Stick Gun: (sorry no Internal Pics)

Nice, slick, and shiny, hows the power doing you? And how much did it cost?

[VH_man]

it shoots at about 700 FPS at 300 PSI, about the power of my air rifle.

the only thing i had to buy for this gun was the epoxy ($3.50) and the barrel ($1.25) so therefore about $4.75....... so pretty cheap.

and it works like a dream...........

[elitesniper]

haha cool, but how much was the chamber setting you back?

[mike1010]

nice and simple but if it is no better than your riffle why not try to make it more powerful?

[sniper hero]

cool I did some simple attempt to built one but no succes.
do you think it's possible to make a how-to for it (please)
a pen gun is a cool gadget for everybody, especially for the onces with teachers they don't like
( I won't shoot my my teacher ever BTW)

[Darkside 6ix]

Thats insane. I have several questions...
How do you fill it?
Is the chamber inside the barrel?
What do you shoot?
Is it accurate?

[VH_man]

well, i forgot to put a quarter or something in the background to show the size but like i mentioned its about a foot long and 1/2 inch in diameter.

As for a how-to, when i construct another one of these (and trust me i sure as hell will) i will post a detailed-as-possible how-to. these arent hard to construct.... but take a bit to understand.

@pvcpsyco: I fill it and pilot it from the Presta fill valve in the back. if you want another picture i will post the picture i have of its "rear end". As for the chamber inside the barrel, yes, it is a Coaxial, but i think you got mixed up a little bit.......... as for what i shoot.... anything that fits. my favorite is .177 cal BB's but i forgot to put a magnet inside of it to make the BB not roll out..... so as of now i shoot shiskebob skewrs.

accurate? not really....... the farthest ive hit a can was about 5 feet. its kind of awkward to shoot. more of a "collectors item" than a practical gun.

Nice gun you got there Dont prestas just seem better as a trigger than a schrader? i use them on my guns as well.

[VH_man]

haha they sure do!!! you dont have to fiddle around with something to poke at....... and by screwing the little nut on the top down tight you can have a saftey...... always nice....

problem is getting them is a mild pain.

[FordGtMan]

Just a question though, how do you get your prestas to 300 psi? Most presta pumps are only rated to 160, and i blew mine up at 210 the other day. Did you use a shock pump with an adapter for a presta?

[VH_man]

i use a shock pump with an adapter. works like a charm.

also, i happen to have a CO2 inflator that hooks up to presta valves....... i dont trust my gun under 1000 PSI of CO2 though.........

[FordGtMan]

Nice vid VH. looks like it had a wee bit of recoil too. I hope to post mine as well if i can steal my sisters camera. Is the inflator made to put all the pressure to go in the tire, or can you kind of regulate the pressure in like having a trigger and going up in short increments? Or does the cartridge just bust and have no way of holding the pressure back? Not familiar with these co2 fillers.

[VH_man]

Well, from what it seems like, the CO2 inflators have NO regulator, meaning it would fill my gun to about 900 PSI......... meaning........ it will most likely explode

i suppose you could just give it little shots out of the thing, but it just wouldnt be safe..........

[sniper hero]

you will post a how-to that would be great !
