schmanman's next large projects

Unread postAuthor: schmanman » Tue Dec 05, 2006 8:35 pm

Well, It's almost Christmas break again, and it will be a year since I built the swat gun, so I figure it's time for another large scale project or two. I've got the old air chambers off the swat gun before I replaced them with 10 feet of 6 inch pipe. so, I've got 10 feet of pressure rated 4" , and 15 feet of 2 inch, since the pvc 2" barrel is not needed with the recent addition of the 20 foot aluminum barrel. I am going to make a 8 foot barreled coaxial, and a shoulder mounted coaxial rocket launcher.two much cheaper, small projects. On spudshot, Killa was throwing around ideas of making a mini swat, with a 2" or 3" piston valve. Anyone with ideas on what kinds of guns to make, feel free to post here. heck, anyone with feedback.

here's it before the new chambers

and after...

Could you shrink that picture WAY down. It is quite annoying.

Build a giant coaxial?

it looks normal size to me. Besides, the site resizes the pics automatically. when I clicked on it, and clicked properties, it said 525x394 pixels. normal size. It says"click picture to view normal size" when you run the mouse over it.

as for the giant coaxial, I don't have a use for one, I want a couple different sized guns, not two big ones.

It's always good to try somthing new mate, what about a fully auto adition to the swat gun, or semi. Maybe make a full scale fully auto hybrid? I'm just throwing rubish out there, but I wanna see somthing new on the forums. Worlds largest hybrid? It Could have dual 4 inch chambers, dual burst disk unions and a 15ft 2 inch barrel. Or maybe make dual sdr21 1.5 inch barrels for the swat gun. Double barrel :roll: C'mon, I dare ya!

well, It's sch 40, so no hybrid there. but I can get a hold of some 10 foot long sections of steel pipe, 2" in diameter, along with fittings for free. my parents wont let me get a stungun, so It will have to be a camera flash ignition. I would use a 20' long 1.25 inch barrel, since I can get a hold of those too. IF I build it, I will try for the sound barrier.

I could do it, but the propane and oxygen injection is the only part I'm sketchy about.

as for the coaxials, or the mini swat, which of those should I make?

I recommend building somethig handheld.You've already got the biggest so another one on a stand will probably disappoint, when it comes to the amount of effort it took to build.
Try a handheld large bore 3"porting cannon.
It should be great to hold and shoot a powerfull cannon like that.

or do some "plinking" muhahaha

ok, so a three inch ported piston gun, handheld? sounds good to me.

how long should the barrel be? just curious what you think.

Awesome idea... You could use some 4" reducing tees with maybe 1.5" handles. Try a 2" barrel and you could shoot 1 1/4 fittings out of it. Fill 2 caps with cement and rip stuff apart!

ok, and about the hybrid, I am going to build that for sure sometime within 2007 . I'm gonna go for the biggest hybrid, and the most powerful potato gun ever built. :twisted: :D :shock:

a hybred with 20 feet of 2" chamber, and a 25' long golf ball barrel, how fast do you think that would shoot? :? :D :P

BLB will know. *hint hint*
