I had some 1 1/2" but its all sdr-21:/
which is great if you are dealing with golfballs, but...I'm not.
And I figure with a coaxial the extra barrel clearance should be fine.
and I'm running the blowgun the correct way

How much hose do you plan on using.
Looks like a blowgun may not be able to pilot it your valve (based on previous experience)

Interesting, I completely overlooked that, perhaps I need to completely redo my designs.

Yes, you may have to do so....
I had a 20mm Tee with 15cm diameter piston and about, probably double the hose length in your design, and it just barely actuated the valve after the chamber was "empty".

Ok guys I am having a major problem
My cannon is nearly complete, but for some reason it doesn't fire correctly, my piston seals and doesn't leak, it is actuated by a 3/4" sprinkler valve but when I pilot the cannon most of the time except for once all of the air went out my pilot.
The piston is a wooden dowel with a few layers of tape around it and it is a really nice fit and slides smoothly.
Is my pilot too strong? or what?
I really am horrible when it comes to piston cannons...
heres a picture of the pilot assembly
if more pictures are needed of the internals or piston I can get those
