where is the vid?

300 Golf balls from ebay, like 40 bucks with shipping = out to 7.5 cents a ball. and there is a potato farm just outside the town where i live, i can get a 50 pound sack for 5 bucks, its awsome!

i have a propane injected cannon, it works fantastic

pre ordered it for 360 2 weeks ago, cant wait

Holy crap Necromancer, that is the best sleeving I have ever seen. This just goes to show the importance of mathematics in everyday situations.

For those wanting to eliminate the gap entirely, cut (2.375*pi)-(2.067*pi) = 0.968" (24.6mm) out of the inner pipe.

thanks alot SpudBlaster15, i tryed ...

i used a anglegrinder with a cutting disk on it. it worked great, cut like butter. I used a caliper and marked the pipe at at 24.6 mm. it was tight fitting it in,but i got it in. i used a hose clamp and a drill to speed things up

Well i did some upgrades to the cannon, i took some advice and bulight a longer barrel with a handel, i came across some awsome couplers that i couldn't pass up. And i added a handel to the chamber and a 12v chamber fan with 8 aa battries so it runs at full speed,and a little toggle switch.

i want to keep it simple, how do i figure out correct barrel ratio?

thanks 4 the input, i used some foam weather stripping on the inside of the hoseclamp so it wont scratch. I might try a longer barrel see what happens.

Well im a new member, and i just built my good combustion spud gun.
Haven't fired any potatos yet but i will soon.Its very basic. Fires 1 1/2 nurf balls good and a 2'' rubber ball pretty good so we will see what it can do with potatos.
