Christmas Present for Max

[MaxuS]

Well this is my present to myself.
Basically the same as the spudgun I made for my mate Nic, but I did change a couple of things.
Changes:
Piston is lathed from M20 Aluminium Rod and has an o-ring on it.
I knew that the 1/2" QEV was overkill so I replaced it with a 1/4" one.
I used proper 1/4" fittings for the fill and trigger setup because I originally used an 8mm compression tee.
The solder job, I think everyone would agree that it's nicer.
Longer barrel and chamber.
Added a breech-loader.

Specs:
1.7m x 15mm Barrel
1.2m x 22mm Chamber
Breech-Loader
20mm Barrel Sealing Piston
Housed in a 22mm x 15mm x 22mm reduced solder-ring tee.
Piloted by a 1/4" QEV
Piloted by a 1/4" Blowgun (soon to be modded)

And yes, I do realise that there are zip ties on it, but I ran out of Jubilee Clips.

loos great. Have you fired it yet? I think the bunched up sealing face may snag up though. Also seems like you get a face full of air from the pilot. Are those 1/2 ball bearing?

[MaxuS]

Yup, I've fired it and it's brilliant, I'll stick up a video and some damage shots before long.
The sealing face doesn't seem to snag at all, the fact that it's greased to buggery helps it slip by.
Yeah, I do get a face full of air, but I always find it quite refreshing.
No, the ball bearings are 3/8" so they need a bit of wadding around them.

wow what a beauty! the only thing i would change is the gap between the breach loader and piston as if it were close it would have better performance because i effect you are shortening your barrel to ~150cm and i'm sure someone will pont out the 'excessive' pilot volume i will refrain because it makes the gun look better and what pressure do you use it and? have you managed to hook up you PCP rifle pump?

[MaxuS]

The gap is there because it's ergonomical whilst laying down.
Again, the pilot volume is larger thasn I would normally go for, but with the use of a modified blowgun, which I mentioned in the first post, it could vent very quickly indeed, not that it's lacking in power at the moment anyway.
I use it at 120psi, basically because I don't really need more than that to do what I want with it.
Id never pump it up with my PCP Air Rifle pump, only because I've got a perfectly good track pump capable of 160psi.

Slightly off topic:
ALIHISGREAT, when do you hope to be posting any of your cannons on the tinternet, I havn't seen any yet..

[ALIHISGREAT]

slighty off topic reply: well i have made one phat qev cannon which i haven't finished and its too cold at the moment to finish it off, i have been busy over christmas so i haven't had the time to finish my 6mm 'sniper' and i have a ghetto combustion not worth posting

[MaxuS]

Fair enough, make sure you do post it as soon as it's finished.
