Thanks for checking it out. And thanks for the well thought out critique. I checked out your stuff, very deep, you'll grow out of it.

You still playin' Yu-Gi-Oh?

what psi do u have to get it up to

[vlxxx]

We've been shooting at 100 psi mostly

100?

thats too little a 2 liter bottle bares 140 more than

we pumped a 0.75litre bottle until it started to expand.

that was a wicked shot

There is one non-schedule 40 fitting on the cannon, so even 100 psi is too much. However, we did try it at 125 psi max, with not much difference in performance.

Thanks for checking it out.

you got a second video... that's better, but there you only have a dent... use some propane or hair spray and that'll make a hole into that junk piece of metal. even with a potato.

use a lever..... that's what i do

how can u make a normal butterfly valve open more easly cuz mine opens so hard its a bitch and quarter of the power goes wasted

[lkpcs]

we pump more than 140 in my air cannon

our pressuregage is broken

mine is made out of all metal parts exept the barrel and the bottle its awesome i think of upgradeing it to a 2 l bottle soon
