if you have a 3" barrel I highly suggest going to the discount food store nearby and stocking up on shitty soup! The fit is near perfect, requiring almost no wadding. The destruction potential is much greater! Here's my 3" barreled pea shooter shooting random stuff - soup cans included! [youtube]ht...

Nice. Needs better ammo than lemons though, does a soup tin fit in the barrel? An empty one could make a good sabot... I did a can of pumpkin pie filling, it was weak sauce though, I was shooting 3" diameter by 6" long chunks of oak wood in that video. No lemon is about to go through a steel hood l...

You shouldnhave went with less screws holding that back cap in. Why so many?? 8 would have been plenty. This is where my supah valve broke due to all these screws.... Still nice thiugh...

Hmmmm, looks like you took all of the parts from a supah valve and put them in another tee..... Very cool upgrade though!! :D No I made all the parts at my work. A supah valves internals would not work with my 4" tee because the supah valve is based on a 3" tee with 2" ports, I did make them nearly...

Well when you get the rest built you should take a red king size bed sheet to the jump field, paint a black dot in the middle, get the cannon ready, make the jump, take the shot during freefall while filming the results from the Gopro and ground levels and if you hit the bulls eye that would be sho...

PVC does become quite brittle at temperatures near freezing so you have to be careful when handling the cannon to make sure it doesn't bump in to anything. I would also advise against multiple firings in cold temperatures. You should read the relevant parts of these documents too: http://www.vinide...

SGTC Megah valve build

Its been about 5 years since I touched a spud gun (had one explode in my hands at 80psi 5.51BAR) was not pretty. but I learned a lot from that day especially on the use of pressure rated pvc. Anyways here's my coming out of retirement build, its a "megah valve" with 3" ports on a 4" tee, giving it t...
