1. Removed the flow control mechanism by unscrewing the top screw and unscrewing the bottom piece.

2.)Tapped and inserted a 1/4" NPT fitting in the top of the valve.

3.) Removed the Solenoid, and filled the hole with epoxy.

Without the bottom part of the flow control valve, all the air from the chamber vents through the blow gun, and nothing out of the barrel.

4.) Cut the top part of the bottom piece of the flow control valve so that the piece didn't hit the 1/4" NPT fitting. Filled the hole in the middle of the flow control valve with epoxy, so air didn't just go straight from the bottom of the diaphragm to the vent through it. Screwed the bottom piece of the flow control valve back in.

At this point, no air would vent through the blow gun, as the bottom of the flow control valve totally obstructed flow.

5.) Drilled a very small hole through the hard center part of the rubber diaphragm. This was intended to equalize pressure between both sides of the diaphragm.

When tested, again all the air would go out through the blow gun, with nothing going through the barrel.

I hope this explains everything. No time for additional pictures tonight.

Hopefully a brainstorm is forthcoming.

Alright, my roccomendation. check the epoxied hole for the solonoid hole. get some more JB weld and fill the entire soloniod socket on the outside and the inside. anso get a 1/4 inch ball valve instead of the blogun. it lets the air out faster and may let the valve open

I'll give it a try and let you know. I think that the entire hole is epoxied, but I'll investigate further and let you know.

Thanks.

As an emergency plan B, I quickly built a Quad 1" pneumatic valve, SDR-21 golf ball cannon for Saturday. Quickly is quite the joke. I haven't slept much over the past couple of days.

Tomorrow I'll be able to test that and see how it works. I'll post a picture of that later, but I still would rather get the 2" valve cannon working.
