How to further mod a sprinkler

Well, I'm needed a valve for a new cannon. A sprinkler valve doesn't have enough flow, and a piston valve is too bulky, and not low profile. So, I modded the $hit out of a sprinkler.
WARNING: Modifying a blowgun may ruin the seal if you're not careful. This has happened to me, don't blame me if you mess it up.

How'd the picture of the new diaphragm get up there?

very nice job, however, it seems that the new diaphragm is in a different place(lower down) than the original, so how exactly does it work?
is the metal peice on the new diaphragm a coin?

It is lower down, which means it moves up, allowing an assload more air through at once. It's like a really high flow QEV, except 8 bucks cheaper and inline.
The metal piece is indeed a coin, a token to be exact. It's thick steel and fit right into the spring, so I used it.

You can, you'll get much better flow.

i cant really see what you did to the blow gun did you just sand it down so the diameter is smaller?

It a really complex process of unscrewing the top and ( make sure you dont loose the screws) taking it off.

lukemc, use a fine file to file it down to about half the original width.
mopherman, where the solenoid was, there is a circle of rubber. Peel it up, then peull hard to get the diaphragm out.
I forgot to mention this:
To anyone who is using this mod, the first time I tried a valve like this, it leaked like hell out the sides. All you need is an O-ring to fit into the circular groove that the diaphragm's edge was set into.

I dont see how a modded blowgun can allow more airflow than a sprinkler valve. The opening on a blowgun isnt but like 1/4". you can get a 1" sprinkler valve and mod it.

Read the original post again, but the whole thing this time.
I'd have to admit, I love it when noobs tell me stuff like this!
