well ive taken it to about 120 psi with no problems

@Mr crowley I'm going to take off the hose period, =) just checked and it does say nsf on them,I was reading the wrong side

@MAttzip, Really, so take off the hose? I was told it will not make a big difference unless i had technolgy to proove it.I'll take it off and see if i have a difference. Im guessing just using a brass threaded nipple? Also this is my first air cannon but i have my BIG BERTHA, and 3 small little ones...

I know the primer job isnt the best, My Dad helped when i wasnt around so please bere with me

I thought my parts were good for pressure wise but, Thanks for letting me know.Ill take that into consideration next time

@ cow, how did you make that?

The ice ammo thing, I find hard to believe

After doing all the math for how long my propane meter, I did an example , If I had a 15 inch piece of 4 inch pipe using the volume formula Then after researching i found once I get the volume of my chamber. Make my meter 4 percent of my chamber volume My chamber volume is 2.4 , Im confused, so make...

@ Doctore, I love your idea !!!, Ill have to try that

But Doctore, what size barrel are you using, Im planning on using 1/2 inch copper tubing,Im using it right now for my double a battery shooter, but like to try differnt ammo!!! =)

I have one gun that im going to modify to do this with, But how much to put in psi with and ggdt thing didnt work once i down loaded it
I will rig up something to my gun to get the propane in.

I have seen mutiple guns with mixing fans, I have seen multiple guns with out them and both guns work?

Do you need them or just make it easier for igntion?

My next cannon is going to be combustion, using propane and a fuel, that why im asking

@ tony48What size is the barrel and coupling?,

Im guessing the barrel is sdr 1 1/2 and coupling i have no idea

How air tight is your design tony48? I dont see any "O" rings

Fnord, i like your idea of taking off the adapter!!!

You could make it kinda like this,
put a hose on the end of the torch then a hose barb on the end of the pipe and on the other end of the pipe put a tire chuck and on your gun put a tire valve and inject it into your gun , which is really neat!!! =)
