Sorry but, i'm having a hard time on working out the dead space for my cannon:
What is the best way to fill and fire one of these, as a 3/4 tee (as bunnings don't have any smaller sizes) fitting on the back of this connected to a ball valve and shrader is a large amount of dead space.
How do i reduce this space
Thanks once again JSR and everyone else for contributing

That one is going to take a bit more than 300 psi to blow it up.jazzman56 wrote:What pressure can a QEV take , would this one do:

Is there some reason you cannot simply use :a piece of black iron pipe, an end cap, and a reducer?
2" pipe should get you to 500cc in a reasonable length.

Maybe I am just ignorant of the wonders of a good epoxy, but I am afraid for your safety if you use any kind of glue, epoxy or whatever to hold the fitting in place. Again, I am actually afraid for your safety because of this. I am not joking.

Moonbogg,
Thankyou for your concern but the diagrams and method outlined on this thread of how to place a fitting in and epoxy it in. Have NOT BEEN CARRIED OUT as a deduced that this was to hard for me to do at the current level of time. (Thanks JSR for the diagram and all your help
).
Gipetto,
I would have used a length of galvanized steel pipe BUT there is no sizes over 3/4 inch (20mm) and is ridiculousness overpriced. It's cheaper to by a extingusher than to buy steel threaded pipe pieces

I think it's just lack of experience with good quality adhesives. I cannot stress enough the importance of a join being well designed and adequately supported, but once it is the pressure it can take is quite impressive.Moonbogg wrote:Maybe I am just ignorant of the wonders of a good epoxy, but I am afraid for your safety if you use any kind of glue, epoxy or whatever to hold the fitting in place.
