I just finished making a few improvements on my mini piston gun. They are:

-A smaller, lighter piston that sits farther back in the gun giving it a bigger chamber and longer barrel.

-A 1" sprinkler valve as a pilot (which in proportion to this gun's size is a HUGE pilot).

-A blowgun trigger instead of a ball valve.

I also tapped the schrader valve and pressure gauge into the sprinkler valve to keep the gun as "low profile" as possible.

Wow, the best part of your gun is the trigger/fill setup. Probably one of the nicest setups I've ever seen. Simply beautiful!

That is the best coaxial I have ever seen.
Not even kidding, I love it.
I'm glad you took advantage using the sprinkler valve in such a way.

Noice!

Thats genious! My favorite part of the changes is the pressure gauge in the side of the sprinkler valve. Ive seen the gauges before, but the center-back connection gauges I get have a large profile. Looks ergonomic to hold, and fire. I seriously might copy you, I'm pretty sure I have everything, possibly look for a gauge similar to yours, but thats it. Hmmm got me thinking...

Well pimpman, if you want a little advice, here's another thread I started about how to make a great piston for it.

I'll post pictures and/or videos when I get the chance. The weather here is a little cold (i.e. dangerous) for spud gunning right now. All I've done so far is some indoor dry shots just to make sure it's functioning properly (which it is). Even at low pressures like 20 or 30 psi it has a pretty loud report. It has a nice crisp sound when it fires too.

*stands and applauds*

Lovely work. This cannon looks like it could pioneer a new wave of well-arranged minis.

I added some better quality photos. They won't post in the right order for some reason though.
