You should go back and ask him to find the proper fitting for it.

I actually lol'd reading this thread.

Wow can't wait to see the damage pics. This could fire some hefty ball bearings or darts.

Nice hybrid man. I really like the look of machined spud guns. That red burst disk didn't come from a pneumatic rocket did it? I have seen something similar before and the burst pressure was only 120 psi or was it 90 psi?

Off an on for a couple years.

You'd get better results modding them look in the wiki on how to do it. Heres the link http://www.spudfiles.com/spud_wiki/inde ... ification

EDIT: Found the link

Nice darts I wish I had the tools/materials to make those!

Nice cannon dude.

@spudfarm I think its to change barrels. It seems like a hassle to have to unscrew it every shot, especially with the barrel supports.

DAMAGE PIC'S

Nice chamber how did you attach it to the pvc it kind of looks like its been taped on...

What kind of upgrades?

For a 2'' piston I have heard axe cans are good pistons. Regarding the lip are you talking about how it gets slightly smaller inside the tee? Because when you insert a fitting or piece of pipe it becomes all level.

My 2" porting piston cannon is done. There will be a test fire later today. I am a little worried about the piston though it is a little short.

With a bunch of PVC, a CO2 tank + reg, and constructing a blow-forward bolt action rifle, I bet you can beat them all.

Who needs a regulator just replace pvc with copper.

I'm pretty new around here so I haven't entered a contest but if I get a chance after I'm done with my piston cannon to make up a prototype of an idea I have.

@Ragnarok: Didn't notice that, Do you like it?

I think you want a 555 timer. http://www.spudfiles.com/spud_wiki/inde ... =555_timer

Thanks man I was looking at the quick links instead.Prices are decent too. My next cannons can be built without leaving my home.

Hmm sounds like fun. Seeing as how many people are on this forum that's a decent prize. I have some idea's for a contest.
