Valved hybrids ftw :D

I know, I'm horribly predictable.
If all goes well I hope to make 2 other valve-based hybrids and one "other" type, all of which could be out this year (*if all goes well...).

And gauss guns are fun too, I wish I had made one while I was still in school... I mean, they're the like perfect weapon of stealth annoyance.

Nothing can beat both large-bore and handheld. The magic of that split moment of recoil accompanied by a relatively slow moving, massive projectile, which still annihilates it's target, is hard to beat. I've shot enough firearms and pellets guns to find launching steel ball bearings or marbles dull. Having a golfball fly from your hip, streak across a field, and ricochet off a tree and land in your neighbors yard in the OPPOSITE direction is hard to beat.

For me, it's high pressure, small bore copper pneumatics.

Got to say a pneumatic. This stems from my love of paintball, as combustions are generally not accepted to use on the field.

Here lately, however, I've taken an interest in the combustion thing (thanks to this site :wink: ) and have recently built a hybrid that should be up and running within the next few days.

Yay, Spudfiles.

I like building things that haven't been done before, preferably large, obnoxious, and ridiculously powerful. Case in point :D

My goal is a reasonably large bore (~1 - 1.5"), handheld cannon which is semi auto and clip fed / breach loading with muzzle energy upwards of 5,000 ft/lbs, accurate out to a half a km or so, with an overall length of 6' or less, and requiring no more external support than can be reasonably fitted inside a backpack. Essentially a semi auto, handheld 50x hybrid. It's closer than you may think :wink:

Big guns own when they blow things up, but snipers get the headshot! :twisted:
I must say having something that can hit a target accurately and unnoticably is a lot of fun, and it's easier to power (I have a bike pump) they kind of make you feel stealthy...like a ninja... Plus you can fire them like a real gun. And I can't shoot big guns freely around here in the city.
However, my next three guns disagree...
1. An upcoming, 2" shoulder mounted pneumaticaly triggerd burst disk with 5 2" chambers with a three foot barrel
2. An egg cannon with a five foot 2" barrel with two 5 foot 2" chambers hooked up to a 2" piston valve piloted by a sprinkler valve.
3. A hybrid. Nuff said.

I also plan on making a mortar sometime soon, but I'll also be working on a new metal sniper with a friend over the summer. A pistol is predicted in the future too.

The "hybrid for school" bit in your sig sounds rather scary actually...

I like small cannons more than big ones, I just can't seem to get them powerful enough. The solution to most spudding problems is more pressure. And I can almost guarantee that you'll get bored of the 2" bore burst disk gun after a few shots. Ammo is too difficult to make, and most spuds are too small. Also, 2" burst disks require quite a bit more material than their 1.5" equivalents, with rather small power gains for 2" barrels.

Oh yeah, the hybrid comment does sound a bit out of context... But don't worry, it's on the smaller end.
I'm thinking that I might try pop can aluminum as the burst disks, which should make the disks less of a burden. Also, I'm planning to make PVC rockets for ammo. They flew well out of another large bore cannon, and are easy to produce. They're also often reusable, and cheap (unless you smash them into concrete). But I do know that potatos do often work (my first cannon was a 2" bore) and I can always sabot things. Hence the egg cannon! :twisted:

Save yourself the trouble, and don't even try pop can aluminum. If you want a stronger disk, just add more layers of foil.
