i love the piston setup, but i bet you could reduce the recoil of the gun by having it flip up to parallel the chamber and barrel in over/under style, so the piston is firing the same direction as the golf ball, and by reducing recoil you can probably help preserve the life of the gun, and reduce po...

your finished? i have two more CAPT tests to take still.

pete i hate you for your amazing-ness-ness-ness (droooooooooooooooool)

I'd take a picture but i dont have a camera, suffice it to say that it's not nearly as messy as other people's but its no pete-zaria-office-room

i hate...
street lamps,
the wind,
slow drivers,
people who impose their beliefs on me,
stupidity in general.
being politically correct
(stupid people are retards because they are slow, thats what the word means!)
it would be easier to name things that i like.

mine was -2, 0

Then what was the point of your original question?

honestly research isnt hard either, it's everywhere, myself i surfed this site for like 3 months looking around at peoples ideas and designs before asking a single question. Look relatively anywhere but if you have a specific problem, I'm sure people would be happy to help, as they did me.

the fan vents for however long it takes to load the next potato, around a minute, and i use it to mix the fuel too for about 10 seconds once it's finished injecting.

yes, they are DWV which accounts for the low cost and me not caring whether or not i die.

edit: I might mention that I am forced to wear ear protection while shooting this, the recoil is powerful and its extremely loud.

actually a few tests and we determined that about 45 seconds is best at full blast. take off 5-10 seconds for extra warm temps and add 5-10 for colder.

Actually I can get damage pics easily, I have a painted target which is 26 gauge sheet metal screwed onto 3/4 inch plywood, most rocks and things I shot from 20 yards go right through. I'll get those up ASAP.

yes I do, I'll search that now.

edit: omg which one is it? There are probably 300 of them.

edit: nevermind I found it.

Its BATF letter more specifically.

This is my 4th gun and i wanted to go big so my friend and i put together $60 to make this. It has interchangable barrels, rear- loading 8ft 2" barrel, 7ft 2.5" barrel, and 10ft golfball barrel chamber 4"x4' chamber fan injected (not metered) propane stun gun ignition with spark strip. http://i126.p...

Well I have a friend who wants to make a nice spudgun, but his mom, who's a lawyer, argues with him that it would be considered a firearm/weapon and that it could be classified as a pipe bomb. I'm trying to find some sort of documents that he could show his mom to prove her wrong. Does anybody else ...

A friend was doing something like this once to me and I acted like I didnt notice or care then gave him a five second shock next time I saw him before he could react. After he got pissed I explained why and he understood but was still angry. He's basically my bitch now too. but we're still friends. ...
