i have taken it to about 35 psi at the max but i want to pressure test it to 6o to see if it can take it. i will be very care ful some other ammo i have used it tiny nails they work well and pen cartrigedes act as paint balls they explode with ink evey where when they hit !!!!
also i want to make the same type of thing with a tomato sauce twist top bottle they look like they are a bit thicker plastic.
P.S. i made this type of cannon because i could not seem to get the combustion minis to work the right air fuel mix and all that.

dont take it above 35,the chamber will rupture,or the lid will blow off.

I don't know if you should be using it at all, I mean, correct me if I'm wrong but those bottles really aren't that thick, I'm surprised to see that it held 35

i said id pressure test it to 60 i mean hide behind a big peice of wood while the compressor pumps it up so no one gets hurt and i see if it is safe to take it that far plus i scraped that cannon to make my new air rifle.

well drac it's like this-my friend made a small cumbustion out off some kind of alumium tubeing and wrapped napkins around hat pins (6"s long), to shorten the story up-he shot me the first time,(misfired), 5 minutes later i had ahold of it, got it ready to shoot, misfired again-shot that same freaken pin through the same freaken finger, during the second removel the napkin and plastic head came off, so i had to go get plyers--OU-FREAKEN-CH !!!!!
the trick is---PULL STRAIGHT !

that sounds like it realy hurt did it go the whole way through your finger or did it just stick in a little bit
