With such a long barrel I doubt it's very loud at all. I have a similar cannon and it's pretty quiet even at 260PSI.

Mr crowley is right, its not loud at all, when i take it up to 400psi it might have a bit to it but at only 150 its quiet, although louder than a commercial one

Just work your way up in pressure and see for your self, you will quickly see what is ok, and what is too loud, and then just go from there.

Beautiful job on the gun mate. I love it. Too bad it's out of commission at the moment but It'll be back!

thanks. without it 200psi hurts your finger in 1 shot. at 350psi its hard to pull even with the lever. now im only waiting on a new pressure gauge and a locking chuck and ill be able to get 350psi once again!

Nice, are you drilling out the base of the slugs or using the as-is?

I am just leaving them solid. i use the slugs for short range damage shots. for sable flight and accuracy i use commercial .22call lead hunting pellets.

...and its about 1/2inch thick jb weld so i dont think its going to break :D ...


I have had JB weld break for me in the past. I broke my clarinet lyre (the spotweld place) and I decided to JB weld it. two days later, it broke again. Yet I trust it in my 10x hybrid... go figure. After all that, I did solder the lyre, and it is fine now, except that I screwed up the threads.

The Morale of the story: JB weld can break


[/off-topic]

nice cannon, BTW!

with the epoxy im not saying its not possible to break, just pretty darn hard to. i had lored some left over jb weld into a circle and when dry it was easy to break with my fingers. so it all depends on what kind of joint is being made and the preperation done to the serfaces before application of epoxy
