ITWOST: Took apart the top of a "Fix-a Flat" can.
(Foam tyre sealer/inflator in a spray paint looking can)...Seems not very useful spud component, although worth saving in junk pile.
I'd guess it could handle maybe 100psi (just the clear hose and plastic tip).
The threads that fit shraders look like pot-metal, die cast ,in black plastic casing.
And the valve is the same as a spray paint or aerosol can.
Noticed the valve on my banged up fire extinguisher would probably make a nice hammer valve, or maybe a longer lever could be attached for use similar to a pressure washer handle. (Not fond of the long lever pull myself though).
Been wondering if my clear 5 Gal. "crystal springs" water jug tank could handle combustion pressure(?)
I have 10' of 1" PVC sitting around.
And an idea to attach the barrel to a T with ball valve for venting/mixing, run the ignition wires with the barrel, and put JB weld and about 4 Hose clamps around the opening.
I would definately not hand fire it probably ever.
So not much fun for me except the clear chamber would look cool whether it ruptures or not. No time for a toy though...
Spring is officially here and I'll be working on my Motorcycle a lot mostly.
I may work on something quick that could double for home defense type stuff though. Never too safe!
