Potato Guns

I've hear about the steel wool tracer and always wanted to try it. Our plan was to take a pop can, cut off the top, then put a little baggie of gas in it. Use a screw to hold some steel wool on the back end of the can. Now the expected result is when the can hits the target it bursts and mists the gas which is then lit by the steel wool.
 





I need to get mine working again. I want to install an electronic ignition system. The pushbutton grill ignitors don't last long.

It's nowhere as big as yours. It does have a nice report though. Sometimes it even sounds like a gun going off.
 
Yeah I hate the grill lighter ignition, it fails all the time. IMO the best and reliable ignition is to use a lantern lighter. Throws a huge spark every time and you never wonder if the grill lighter has stopped sparking.
 
Speaking of steel wool...It was fun to set some on fire today at work with my 2W 445! I love my job!
 
Lol, nice. Those pneumatic's are no joke and stupid powerful if you get the release to be quick enough. Downside is though, no BOOM. It's much less fun for me without the boom.

i pressurize it to about 85-90 psi on average. damn straight its no joke i have a screw on 1/2 in tube to shoot marbles out of. they will tear through anything :eek: it actually scares me
 
I made this one a couple of months back while I was laid up at home. I found the basic plans at spudgunner.com and did some mods.

"Bolt action" pnumatic sniper rifle

Air pressure guage and shrader valve on the end.

Orbitronic sprinkler valve with trigger.

Can put up to 90 psi in it and thump she goes. Still need to add a scope.
 
No DUKEA, it's a 1/4" barrell in side a 1 1/2 reciever. But I can swap it out for a larger ( or smaller)one by unsrewing it from the valve. Mind you, it has to have it's own reciever.
Pre-cut spuds go pretty far. Spuds with bolts imbedded, even farther. :D
BTW if you noticed, I'm a lefty.

I like just about everything about that gun, except the burst disk design. I know it's necessary for hybrids though, and 1200+fps holy crap it into the realm of a firearm. If I could say anything from my experience though, it's use a 2.5"dia barrel. Tennis balls fit with the perfect amount of compression as is, much better than potato's IMO.
 
Somewhere I read that you could get good flight from a golf ball in an 1 1/2" tube, but the golf ball I measured was a little too big. You would have to sand the divets off. Too much work.
Did you check out the taternator in the link above? If I ever get around too it, I want to do a propane oxy set-up,but not at that level.
 
I saw it, pretty slick, I've always liked to use Mapp gas since it burns a lot hotter. I draw the line at an oxy setup though. An accident there can cause some serious damage, lose some body parts and your hearing.
 
Was the injury with pvc or steel? Steel is less like to blow. Only time I would use pvc in a fuel powered gun would be small shots of butane or ether.
 
The injury was with PVC. We found that on a larger scale the chamber is more prone to expansion during the shot. The injury happened when firing and the female adapter on the end expanded and the cap blew off hitting my hand. Surprisingly though the threads on either piece was completely undamaged. In the video on the last shot you can see the cap blow off the back end again. We've since retired that gun and every gun I've made since that has a 4"+ chamber I put a few hose clamps tightly on the female adapter for piece of mind.

Yea, I've read a lot of horror stories about PVC and others suggest DMW because it cracks instead of breaking but doesn't have the rated PSI. For me, I don't trust either for a combustion chamber. I've always wondered if anyone has put a pressure test guage that stops at the load to see just how much pressure it's getting when fired?
