I put a little chapstick pump on it, and it helps a little. Not as fast as taking the plug off an shaking the old out, but it works.

It was just an idea, I kinda designed it for a slightly smaller gun, you could scale it up and cast a hot glue piston or a dowel with a oring on it

Yeah it wasn't permanent, I mounted it in a bushing that took the place of the plug in the back. Maybe I'll make a hot glue casted piston in 1/2 pvc for a pump.

Sounds good but as pointed out it not a pump, more of a air cycler

Alright, so I made a 1/2 pvc body, hot glue piston and put it on a bolt, lots of vaseline for lube, but its really tight and hard to push and pull. It delivers more air but still not worth the effort. Back to the drawing board again

Sand down the piston the bit tons of vasaline

I already have a butt load of vaseline on, and I don't even feel like fiddling around with it anymore, I want a better design anyway.

Well just put in a fan from like thE dollar store

It's a half inch chamber, remember? I might get a tiny motor and make a fan out of it.

Well buy like a toy cell phone or something, they have tiny motors and battery

Haha my little sis has a bunch of those...

Guys, just use a syringe, it's the same concept.

I tried to find one, but I think it got thrown away. I'll keep my eye out at drug stores for one.

Oh, if you can't find a syringe you could try and add a small fan into yur gun, a bit more complicated but it could be done. Try finding one in an electric toothbrush, also cellphones have a small fan. I'm not so sure how hard it would be too make an on and off switch for it though.
