This isn't exactly a multi barreled Gatling gun, but it is a crank fired gun that I thought some of you might like to see
my progress on so far. It is getting real close to being finished.
My latest water & air cooled Ruger 10/22 stock build. This is my 3rd of three prototypes. This is semi auto, NOT full auto. It has the option of using a crankfire trigger activator so it can be crankfired like a Gatling gun.
This 3rd prototype is quickly convertible from truly water cooled to air cooled in about 30 seconds.
Although the final surface finish has not been applied yet, these pics give a good representation of how the convertible to air or water cooled stock will look when I finish it.
On my water cooled barrel jacket, I used a front sight of my own design that resembles a Browning 1917's hooded front post sight. On the rear I used a sight mount of my own design that holds and allows spring assisted raising of the WW1 Enfield rifle's ladder sight, that I have modified to enable to be used for windage in my sight mount. Works very well and looks historically representative of tripod machine gun's sights from that era my stock resembles.
My first air cooled only prototype I built in 2006-2007,

Last night I made the quick removable rear ladder sight bracket. That once removed, will not have any unsightly threaded holes. So that I can mount the spider sights on the air cooled version when I remove the water jacket from the water cooled version. I realized that I could mill off the triangle on the right side of the rear sight bracket and just keep the triangle on the left side (like on a real Browning 1919) and still be able to secure the sight bracket without it having any kind of looseness or "rock" at all. All that is left to do with this sight bracket is to drill and tap the sight riser plate for the ladder sight's spring, and then to drill the sight protector "ears" and install a small diameter bolt through them and the ladder sight so I can effect windage. The 1917 Enfield rifle ladder sight I am using did not have the ability for windage. It was a flip up type only. So I tapped its pin hole where it flipped up, so it is threaded. The small diameter bolt I will put through it will enable me to turn the bolt to make the ladder sight travel left or right on the bolt, thus effecting windage. I left the sight protective "ears" a little higher than I needed until I mount the ladder sight's spring and the sight itself. Then I may be able to trim the “ears” down some maybe an 1/8th inch or so. So when you look at it now, the protective ears may look a little higher than they will eventually be. When I made them, I figured better to have them too high and be able to trim them after I finished mounting the sight and its spring, than to have made them too short. You can always trim metal, but it is hard to add when you have cut off.

Below, Prototype #3 (latest), Convertible to air or water cooled in about a minute and new mount for camera tripod.
First five pics I forgot to install the "BMF activator" crankfire trigger activator before taking pics.
So the crank isn't in these first five photos. Has MWG 50 rd teardrop drum mag in gun. I used everything I learned from building first two prototypes, but third prototype is a completely different design from either of the first two. I later trimmed down that threaded rod sticking out of side of rear sight bracket. Spider sight is attached to perforated shroud, so fake receiver is stand alone and works for either water cooled or air cooled versions.

Below, ladder sight can be left on gun and folded down to use spider sight, or ladder sight bracket can easily be removed to just use spider sight.

Rear sight bracket brass nut (to receiver) only needs to be removed from one side and threaded rod pulled out just a bit to remove rear sight bracket. Then push in on threaded rod with brass nut from opposite side, and reattach brass nut and washer on other side if one wants to remove rear sight bracket and only use spider sight.

Brass nut removed from threaded rod that holds rear of receiver and also rear sight bracket, which removes very easily to take rear sight off with no hold in top of fake receiver. Here threaded rod is shown pushed in and flush with fake receiver so rear sight bracket could be lifted off. No screw holes for rear sight bracket. Same threaded rod that holds Ruger receiver inside fake receiver also hold rear sight bracket. Only needs to be held by threaded rod on one side since other side of sight bracket fits fake receiver tightly. Makes for easy removal too.

Below four pics are of rear ladder sight housing. I used a 1917 American Enfield ladder sight, drilled its pin hole larger and threaded it to effect windage. It flips up and down under spring tension. Turning brass nuts turns threaded rod to effect windage. Notice I made one side of sight bracket triangular to resemble triangle under rear sight of Browning 1917 and 1919 guns.

Below, closeup showing brass knurled nut and washer removed ready to pull threaded rod inward a little to lift off rear ladder sight bracket. Then just push threaded rod back and re-install washer and nut. No ugly holes in top for rear ladder sight bracket to be seen if only using spider sight. Clean that way. Makes the threaded rod hold rear of ruger receiver in fake receiver also hold rear sight bracket. Threaded rod replaces large Ruger pin behind bolt and has built in plastic sleeve over inside of threaded rod (inside Ruger receiver) to be bolt buffer and also protects threads on threaded rod going through Ruger receiver.

Below, it's not really necessary to remove ladder sight bracket since you can fold ladder sight down to clear sight line to use spider sight in air cooled configuration. Also makes for changing from air cooled to water cooled faster since the water cooled HAS to use the ladder sight.
