First air cannon
Posted: Sun Apr 29, 2007 9:49 pm
I built this as my first air cannon and I think it works great.
I was shooting with the 2" potato barrel about 165+ yards.
A golf ball probably about 300+ yards.
This was only at 60 - 80 psi.
The chamber is 4" x 30" pvc and the barrels are from the top:
1 1/2" SDR-26 sleeved in SCH-80 for golf balls
1 1/4" pvc ramrod with a flat cap on the end - fits perfect in 2" barrel.
2 1/2" SCH 40 for tennis balls
2" SCH 40 for potatoes or ice slug or other general use. (attached to cannon)
All the barrel ends are 2" male thread to be interchangeable with my combustion gun as well.
Valve is a Orbit 57020 used in

I put a ball valve in as a "safety" then a blow gun.
The second input on the sprinkler valve works great for the fill valve and pressure gage.
My gluing is a little sloppy because I was going to paint it some time.
