Sprinkler Valve Question

[MrPotatoHead]

I am building my first cannon and am building a pneumatic. I am using a 1" sprinkler valve. I am going to modify it by drilling it and adding an air tool. I would assume I need to plug the hole that originally had the solenoid in it. Is this correct and if so, what should I plug it with?

L.J.R, that didnt help a bit, and potatohead, use epoxy.

666 posts benny the devils number i believe....
anyway on the topic of valves i saw a piston design using a pringles can as the piston but aparntly its too light-weight,
if i build one would it help if i put a long bolt through the can to hold some rubber on as the thing that seels the barrel instead of just glueing the rubber on and fill the can with dry-hard foam stuff to add weight?

I take it not a lot of pressure builds up in this portion of the sprinkler valve.

MrCrowley, hes not building a piston cannon. This is his first gun and hes using a sprinkler.

As Benny said use expoxy. I personally use ones that set "hard". JBWeld and PC-7 are the ones I use. Other "goops" and "expoxys" will expand when exposed to pressure and Ive even had some blow up into a ~3" bubble and pop. Or you can leave the soleniod in.

i know he wasnt but i was looking at the pringles piston just as i was posting so i thought i would ask here instead of making a whole new topic

Pimp, are you sure that you mixed the two parts equally?

Well I thought it would, This is taken from the how to link.

Additional notes:
If your now obsolete solenoid is getting in the way you may simply scrap it, however you must fill both small holes in the solenoid port with epoxy.

Now isn't that basically what you said.
