... or even better built them? ... or best of all, willing to share about their experience designing/building guns?
 
mine are all air powered and launch nerf rockets at ~230 fps

Home Built

Well...I did cobble up a pretty nice zip gun when I was about 10. Even used a rifled barrel cut from and old Glenfield .22 rifle. Worked pretty good too. Sadly, the ol' man beat it to Helen Gone with a heavy hammer when he found it. He did the same thing with the supressor I fashioned from an old lawn mower muffler and stuck on a single-shot .22 rifle the summer before. He just wasn't any fun...:rolleyes: :D
 
I have a very rough, unfinished, bullpup FAL sitting in my basement. :) That project had to take a backburner for awhile.
 
Things that will never be allowed to exist... Fictional Ammo included

techline.jpg

SpiggyTech CQB Weapon, featuring the melonslice magazine, loads from the side like a STEN, but it's curved downward to save space. Includes a rail system mounted launcher for grenades or beanbags. Chambered for Spiggytech Stopper type Ammo

SpiggyTech Carbine, Folding retractable stock and rail system, based off the CQB Weapon, chambered for the much bigger SpiggyTech Shredder type Ammo.

SpiggyTech Technical Shottie/Launcher, Biggest meanest 25mm automatic shotgun with a drum magazine ever concieved. Easily retrofitted to launch 35mm grenades

I love my math class, it's just that boring!
 
Designed, yes; built, no.

I managed to trim my lilac bush today. It's a bit less than even. The job took well over an hour. I ended up with a couple cut fingers. Some people are just considerably less handy than they used to like to believe.
 
Back when I was 10 or so and thought that Chuck Norris or Jan Michael Vincent holding mini-machine pistols was the coolest thing since sliced bread, I thought up a few.:) I was always drawing pictures of James Bond cars with more guns than they could possibly store ammo for.

But no real designs...
 
I've built a few black powder kits. Not so hard to do and the results are nice if you take your time and pay attention to detail. I've used them quite a bit hunting. Been offered lots of money for them by admirers. Haha, as if... But it's a nice compliment to receive.
 
When I was 13, I dismantled a pellet gun, cut the barrel down to ~8", welded a nipple in the back and attached it to a frame I made by bending aluminum flat stock. Then I took the lockwork from a metal capgun. I pulled bullets from .22 LR shells and drove them through a swedging block to make them .177 diameter. I would use the powder from the .22 shells and regular red plastic caps for ignition. It worked quite well, actually-despite getting quite a few pieces of plastic caps stuck in my hands. A short while later, a friend and I built .22 cal smoothbore zipguns from assorted steel stock taken from his high school's metal shop. Mine was all welded together with a basic trigger and pistol grip; the barrel was hinged and used a briefcase latch to lock closed. His, however, employed a simple pinball-style firing pin (pull and release) and he used hose clamps to secure the barrel. Tragically, while loading his above a table he managed to drop it square on the back of that pin and it discharged. The bullet went into his left cheek and lodged at the rear of his skull. He survived after 6 hours of surgery, but the effect on his memory was profound. He also has to take anti-siezure medication and be careful not to hit his head hard, as the bullet could dislodge and cause an annurism (sp?) (it was too close to an artery for surgeons to remove it). My zipgun was confiscated by police later.

I have since built a couple of single-shot smoothbore blackpowder pistols, but have not fired them in years.

These days I stick to the ready-made variety.
 
-I had a matching pair of genuine imitation 1911 dart guns blue of course with the dancing horse.
I think the Drug Store had a Quality Control problem, my ammo was suction cups. I wait until the coast is clear , pull a chair so I could reach the stove top, and used needle nosed pliers to insert them really nice needles . Now I had a dart gun with dart ammo.

-A boy, a .22 rifle ,OTASCO Muffler for a lawn mower and steel wool...err...well everything was quiet with that muffler, until my Uncle turned green... then he grinned, helped me shoot some ammo , then the muffler got beat all to hell...

-It seemed like there was a need for left over bullets, like .22 lr , .38spl, and on up to like '06 ones needing to be fired from shotguns. Well, there I was with a single shot 20 ga Uncle said someday he get around to fixing the stock he bought for $5, all that stuff...I didn't really understand Sabot, but I learned. "How come this one here is key-holed - what did you shoot it with...??"

So a few years later, and remembering the exact words " do not make any Sabots for a shotgun" . I got .32 to sabot from a 1911...and not keyhole.

My uncle dropped his cigar...started toward me, then went into the house, head shaking and mumbling something. He got to doing that lot the older I got for some reason.

Then I found this little light off a display. I tell a older fella, not a mentor, just some guy out shooting.. " you know some day, there will be itty bitty batteries and folks will mount lights to send a beam of light to target. Be great when folks don't see too well...

"Son...that is almost stupid enough to make good sense...a light on a set of stocks as an aiming tool...".

Uncle passed away, he would have like the 28 ga slugs I made some years later...
 
Piece of pipe, pipe plug with hole drilled in it. Firecracker propellant and ball bearing projectile.
It worked.
 
=)

it's nice to know that if one day the chinese/islamic jihad/frogs/penguins invade I'll be able to pick off all their sentries quiet-like with a lawnmower-muffled .22.

home brew bond hehe

all this talk about mufflers and homemade cannons almost makes me want to try it.

then i read sm's post, count all the injuries i've gotten over the years doing just such stupid things, and wisely choose to stick with my sig.
 
Not a firearm, but I'm designing (and sooner or later fabricating) a drum magazine for my Saiga 12. 25 rounds = full round of skeet without reloading. :D
 
DR, that's delicious I imagine it's gonna be pretty... tremendous, too. Also heavy. Make one that'll fit in the mag-well of those nifty Sidewinder doohickeys that Knoxx makes, and I'll beat a path to your door!

Y'know, me and the world.

Then, doorbell. Bam!

To return to the topic at hand, I'm in the process of building a better Potato(e) Gun, which I've affectionately termed the Potato(e)zooka.

In the cities, in the 50's, any kid that couldn't build a 22 zip gun was lacking something in his education.:D

I designed a 1/4 inch bore hand cannon. Even mixed our own black powder.

I cut down a single shot Remington rifle into what I called my Pirate pistol. I didn't know that was illegal.:) No sights but with a little practice we were hitting soda cans in the air. I later bought a new stock and barrel and gave it to a friend's boy.

When I was about 16 I designed a machine gun but didn't have the tools to build a working model.

And in the 80's I built my M2 Carbine "conversion kit". Mostly that's just licenseing the parts but at the time I had it modify a couple M1 parts.
 
Made: Only the Dragon-Lance 2" compressed air cannon. Tested to 100 PSI; lobs a marshmallow (unaerodynamic as hell!) 300' with a ~ 30% charge. Used to down a damaged tree after Charlie (not as cool as you might think, I just threw an improvized grapple and we pulled it down)

Designed: working on the Quarter-Pounder. 4 barrels of 4-ga, milled from a block of steel 3.5" x 3.5" x 18" -- I expect this to require a powered exoskeleton to fire ^_^

Various mecha-mounted systems. I'll describe it later if I can find this thread after microbiology.
 
I have (almost completely) designed a pre-loaded drum mag for .22LR rimfire. It would have a metal housing that would fit to the most popular receivers (like a Rugar 10/22, for example) and which would have the wind-up drive spring. You would them buy pre-loaded 250 or 500 round disposable (thin plastic) packs that would drop into the housing and let 'er rip. Throw away when empty. The guys that have those double 10/22 crank operated gatling guns would love it.

Sarah Brady would have a cow and I can see the VPC declaring them "the ammunition feeding mechanism of choice for drug dealers and terrorists." :evil:

I'm actually working on a few home build projects. I'm still waiting on parts but I hope to have (semiauto versions of) a 1919A4 and two Yugoslavian AKs done within the next few months.
