Asco valve

Put this together this afternoon.
I was surprised at the power and noise. Shot GB's at 80lbs.
Wanted to put bolt action barrel from L7gbl , will take a little more work.
Cannibalized parts from 3 launchers.
Pipe and fittings cost $170. Working w/steel pipe is great no waiting for glue to dry ,changes are easy. Cap was drilled and taped for fill and gauge.
Rate of fire would be very fast w/bolt action or hopper because valve is chamber fill. I tried dry firing every time the gauge hit 20lb ,worked flawless.

Wow, that is one awesome looking cannon! I love how the chamber is also a stand

I like that for so many reasons- well done on a very innovative cannon

you don't have to fill the asco valve from the pilot, I thought you had to since there is no spring on the diaphram

[hi]

On the diaphram there is a washer that adds weight to the diaphram, taking the place of the spring.

I really like the design, especially the stand as the chamber.


What are you filling it with that would allow it to be so fast if used semi-auto? I'm guessing some sort of CO2 tank?

The diaphragm is rather snug or taunt against the seat.

I will get the chronograph out.The weather has been mild in the NE.
Oh ya I can shoot in the cold now

With that stand I just tilt it back for elevation.

daberno123 With a compressor it fills fast. As fast you could load with bolt action it would have filled to 40-60lbs.


I shot over the chronograph today.
Put a little paint on, cold galvanized spray. Looks better.
Had my 'little brother' pop off a few rounds.<a title="IMG_0596.jpg" href="http://s116.photobucket.com/albums/o12/ ... .jpg"><img src="http://i116.photobucket.com/albums/o12/ ...
