3/4" barrel (I might make more, since they screw on)
2" chamber
1" sprinkler valve
Pressure rated hose and blowgun valve
Presta valve with Schrader converter (had to buy at a bike shop)

I don't think it's too terrible for my first pneumatic.
Telling me anything I screwed up on would be greatly appreciated.

Thanks

Yeah its a good start, you've got a massive pilot volume, much more than you need. Also, if you don't want to reduce the gap between the barrel and chamber, then you'll be needing a support to take the stress off of those elbows.
Good job.

Yeah, I'm planning on putting a support between the barrel and chamber. It's pretty damn wobbly without one.

is that a clean out cap those are very dangerous on pnematic also cut down on the pilot volume a ton add barrel suports and damage pics also what are you pressurizing this at because if that is a cleanout dont pressurize it those usually arent pressure rated

Nice gun for a first, but why didnt you just put an endcap on the 2" chamber? It looks like the plug you put on the end is DWV, but again nice first.

Can I ask why you made your barrel so far off from the chamber?

reduce the distance between the tees for more support. Just use a cap instead of the cleanout. And how long is your barrel?

Shorten that hose and feel the difference!

Also, ShowNoMercy, excellent avatar bite the kerb!

I made it like that so that I can fire it with the barrel resting on my shoulder, with the chamber under my arm. I'll add something to support the barrel better.

Makes a whole lot more sense put that way. You going to paint it? And how accurate is it?

I might paint it black...And I haven't got a chance to shoot it much yet. I've only shot a few batteries (and a glue stick, which just happened to fit perfectly) at a tree in my front yard. Seems pretty powerful. I think I'm gonna go to the soccer field tomorrow and see if it's accurate.

Thanks

Hey Nato, nice first effort. What kind of damage does it produce?
I could picture JSR squirming in his seat as he took in, then in, then in that longish pilot hose
Welcome to spudfiles mate

I bet that thing is fun to shoot.

The only thing I would suggest (besides dropping the cleanout) would be to add a barrel support. Also, for more comfort, have you considered mounting the blowgun?

I'm glad to note however that I seem to have drummed it into people's heads enough for them to comment about it too
