Good or bad idea?

Unread postAuthor: jsefcik » Fri Jul 12, 2013 11:58 pm

I built a cannon using a dust collector valve nd I understand dead space nd all the stuff but I wanted to connect a small hose after my ball valve which is my trigger now, want to move it so its more convient to hold nd more fun firing, ,, will this affect my performance nd have any negative results?

It will decrease performance, but probably not enough to notice without a chronograph.

I'd say the ergonomics is worth the very slight performance hit, personally.

Remember these type of valves are designed for a remote pilot unlike a standard diaphragm (sprinkler) valve. That is why it has two internal valves.

I remember seeing a spec of less than ten feet for the ASCO 8353H038 (1.5 inch valve).

If your trigger valve is at least 1/8 inch and about a 2 foot long 1/8 inch hose you will not notice any difference.

Dewey-1, thanks for reminding me of those Asco valves. I still have one from back in 2008 when I got a few off eBay for like 15 bucks each (I think you did too!)
