Here's two projects I completed this week.

4.1" "can" mortar.

50 caliber muzzle loader Gatling gun W/display stand.

I like the way you throw out the word "stuff"... That's unbelievable! Nice work!

Mike and I looked at these while we were visiting and the mechanism on the gatling is unique and the hammer seems to snap positively upon the nipples. When Dom cranked it at a moderate rate it seemed to be about 3 shots per second, maybe 4. I am most interested in a light weight mortar to have fun with and his intermediate can mortar fits the bill quite well. It's between beer can and 2lb coffee can size, maybe small coffee can size. The tube was easily lifted with one hand! Not 200lbs like our SBR 4" 1797! We prodded and poked that Gatling quite a bit and Dom spun it all around. Looks pretty solid to Mike and I. I agree with the person who suggested a video clip. THAT would sell it quicker than anything else.

Regards,

Mike and Tracy

Actually it is more a Pepperbox on steroids than a gatling gun!

have you given it a good testing? the pepper box pistols were known on ocasion to chain fire if the caps

were not seated well, it was also the reason most designs have a shield around the cap area.

I am not saying this as a critizism just observations. I for one like it!

Neat! When does the golf ball Gattling debut?

KABAR2 - Methinks the pepperboxes had their nipples a little closer together than this one has.

As we all know, the farther apart the nipples, the bigger the, uh...space in between them...

Hmm nice stuff, Like to have the Gatlin gun in my toybox. Seriously that Gatlin gun is impresive. Dom you make some serious "heavy metal" and I thought the Golfball "Dictator" mortar was massive....

dominick · « **Reply #14 on:** October 23, 2008, 03:34:56 PM »

Thanks for the compliments. I actually fired it with blanks and it works well. I was surprised at how heavy a spring I needed to ignite the #11 percussion caps. This made the handle harder to turn so that's the reason for the longer crank handle. It fires 4 barrels per revolution. I saw an original firing and it fired only twice per revolution. They have a worm gear drive which changes the ratio and slows the rotation of the barrel. The possibility of mis-fires is the reason that I did not make a barrel cradle assembly that wraps around the front of the gun like the original. It is a smooth bore 50 cal with 1" od barrels, uses a pair of industrial chain sprockets intermeshing for the 2 to 1 ratio angle drive. When you turn the handle, the barrel rotates and the spring loaded hammer rides up the ramp and drops onto each percussion nipple. It's a very simple mechanical arrangement. This is actually the precurser to a [golf ball] Revolving Hotchkiss Cannon in the future. [Someday]... ...[Chambered barrels of course] Regards, Dom

Ahem...I've been busted by a Double D?

Back on topic, here's a 22 cal Gattling-type gun I designed and built many years ago. I didn't know of Dardick's guns at the time, but it works similarly. Rimfire shells are loaded into steel sleeves (chambers, really) fed by a modified 1911 magazine, fired and then ejected out of the opposite side of the receiver.

It's similar to Dom's design in that a spring-loaded striker is lifted by a cam and dropped onto the firing pins when the chambers come up to TDC. I'm sure a similar arrangement of an internal striker/cam could be used for a black powder Gattling if the nipples were exposed for capping at the rear of the receiver...

Dominick: That's some great work!

Victor,
That's an interesting mechanism you made there; when you say modified 1911 mag, I assume your talking about a 45 ACP clip that fits into the rectangular piece of metal attached to the cylinder and then....... a rotary mechanism strips the rounds from the clip and an (internal?) firng pin strikes the rimfires??? Are the four threaded holes suppossed to hold threaded barrels?
I read an article not too long ago (I think in the American Rifleman) about the Dardick gun and its "trounds". I'd never heard of this gun before, this thing is a trip, it looks like a space gun toy from the 50's. The writer said the price for collector's was going through the roof for both the gun and trounds because of their rarity.

Victor3 · « **Reply #17 on:** October 24, 2008, 09:38:11 PM »

Boom J,

Yes, that's how it works. 18" threaded 22 cal barrels are screwed into the bronze piece at the front and tied together with a ring at the muzzle end. A 'tiller' with a grip on it is screwed into the rear of the tripod mount to aim it. The 'chambers' are shaped like a 45 ACP round to fit the modified mag. It works well, and IIRC will fire ~300 round/minute.

I originally built it as a prototype, thinking it was something new that might be patentable (this was in pre-internet days). Then I found out about Dardick.

I never thought of using a similar design for black powder until seeing Dom's one here. If the parts to make it feed and fire with firing pins were deleted, it would be fairly simple to make a BP one.

Here's what the internals look like...

This is a 38 cal Tround...

Maybe Dom could make me a golf-ball one.

Victor,

Thanks for the response about the .22 rimfire gatling gun; I have a cousin that's 62 that worked in a few gun shops when he was a younger man, and he recalled that he could have had one of these Dardick's for $70-$75 bucks. It's a pity that foresight is no where near as accurate as hindsight.

Dom, that is a neat rear sight assembly that you've put on the gatling. Will you be incorporating it on other designs?

I'm working on a more refined version for cannons. I will post photos of it when their done. Dom
