SpudFiles

Yeah I use smilies when im slightly confused and trying to cover that up, make the reader even more confused. I wasn't sure exactly what you meant it could of gone both ways, but yeah the design seems to work for shouldering the cannon as long as your not shooting anything to heavy as the recoil will push the QC into you.

I had 9, yes 9 2" tee's to work with and managed to incorperate 4 of them.

Bought them for a special deal so I had alot to work with the after a few hours of tinkering with the design I came up with that.

I have about 50 spudgun related video's I've taken myself so I just got all the one relevant to this gun(SGA) and put them in windows movie maker, didn't really care what order they were in.
Near the end of the video when its clear it was my first shot at the table thing with a golfball there was other hole in it slightly larger to the right which was from a potato.

Edit: Update pictures of the piston pilot setup.

Added update video of the sabot shots.

Wow great gun I like how you mounted the piston valve on the gun.

you should really have breech loading it would be a perfect combination with that easy refill setup

Yeah I probably should, I need to get a much longer barrel then my current 3' one, maybe i'll put breech loading on that.


Edit: This is for you DCO to prove I did not C&P this on rotteneggs.com from my instructables page.

im guna build my first piston valve and i was wondering what you guys think are the best piston and piston seal face materials and how to go about building them
thanks so much guys
-tom
btw thats an awseome cannon you got there great work=]

neoprene sealing face,and a machined piston is the best but a hot glue piston is a great stater and is easy to make.

you should have used a sprinkler valve as a pilot with a blow gun would have been easier to aim/fire

I do now, I just haven't updated it.

ight, so i make a piston just from striaght hot glue? and if so how?
thanks so much guys

You can make a piston from what ever you want, have a look at my tutorial in the how-to section, it's a sticky on how to make one out of a deodorant can.

UPDATE:

Check out bottom of first post, new pictures, I changed it up a bit, sprinkler valve, black paintjob etc.

WOW MrCrowley that things looks crazy mean now! holy, bet its realreally really loud now looks kind of like my burst disk cannon

Hahahahaha yeah it's bloody loud, as I said the recoil is awesome with the T-Shirt.

Love the stand on your cannon btw, don't think it could hold the SGA, it's about 14pounds now Most of it at the back too.

ha thanks you think that recoil is awsome? try water haha
dont forget the video
