This pic was taken yesterday 01/09/16. 1874 Camel in .45-70 nearing completion. I still have the feed hopper to machine. This is the last major part of the gun to be done. Gear blanks are at the gear cutting shop and should be done in a couple of weeks. After the gun is done I'll start on the tripod parts.

Where is everyone ?

Spent a good part of the day learning fusion 360 and drawing up the DE housing with all its details, including the threads. It made me pull out half of what little hair I have left but should be worth it in the long run.

So I have been quietly working on a 38/357 Gatling Gun of my own. Today it was above average temps so we went to the range with 150 rounds to give it a try. It is very much based on what bruski has posted on the forum, with a few mods. Extractors are a flat formed spring, similar to a marlin 336, carrier is one piece 7075T6 AL, Barrels are from the guy in Sacramento. Cocking ring and recoil lug are "one piece" which was machined out of two pieces of DOM machined separately and then placed one withing then other and silvered together. This is all on a manual lathe and manual mill, no CNC, not even a DRO.
This was somewhat of a proof of ability test, now I will go back and start cleaning up, finishing out. I did run into one issue, cartridges jamming up on the feed. It seems like some of my brass has a little thinner heads (actually I think some are rounded a bit on the edge) than the others and it managed to wedge one rim behind the other. For the folks who have experience on this, how does your groove depth relate to the head thickness? Not sure if I made the groove a little too wide or not wide enough... I milled it out off a piece of 3/4 sq AL, so I figured I would just try making a couple up with slightly different parameters and see what works better.

Update: Now have about 300 rounds of live ammo thru the gun and it is functioning flawlessly. 35 rounds takes about 3 seconds and is a real riot. I had a scrap of 6x6 post left over from building my pole barn that I used as a bullet stop, well it split in half from the trauma, there is about a inch dia ball of lead in the middle where a bunch of bullets went in the same hole. I made up the final top cover in brass, along with its latch. Remaining now is some cosmetic parts, the oscillator assy, elevation wheel, sights, knobs for the rear cover and a few other small items. Functionally its 100% as is. I will make a video when I get the cosmetics done.
Meanwhile, I am gathering materials for the .410 build. Got a piece of 4"ID brass with 3/16 wall, 15 inches long which should work great for a housing. Have the 6 mossberg barrels in hand.

Am I the only Odd-Ball ??
Maybe......... but with all the guns you built, NOBODY dares to say a word !

tetrahedron? isn't that some sort of antibiotic used for the flu?
Ok, I will take a guess at holding it, tabs would be the first thought, possibly some V blocks? Last guess, the old superglue trick.

I took a break from the Gat project since July and returned to it about a week or so ago. The cocking mechanism is completed and installed. I assembled one bolt (all bolt parts are made) and tested it. It cocked and fired a blank. I am now assembling the remaining bolts and shaping the firing pins, two more to do. I tested all the assembled bolts and they function as intended.
Today I fired a 3 round burst (blanks), its so quick it sounded almost like a single shot. I can't fire normally yet, I have not made a top cover or mag at this point, but soon ! I am going to give a whirl at 3d printing a top cover and mag for test purposes, that should be interesting. I got the 3d printer last year, assembled it and tested it quick but have not done anything with it yet.
I have a few things to tidy up, gotta make the bolt insertion knob and knob for the cocking switch. Right now I just have a setscrew shaft collar on the cocking switch, no spring but it works just fine that way.
More to come........... ( PS I got a whole coffee can of blanks at a local flea market for $5.00 this summer, perfect for tests)

Now, on to more important builds, what’s up
with your RDEGG build ?
That build was looking great last time
Funny you ask, I resumed the project a couple days ago after taking a break for the summer. Cut the T slot in the completed cocking mechanism and switch. Probably going into shop today and fit it in the gun. That will get me extremely close to test firing on a single shot basis.
I have been considering 3d printing a prototype drum magazine and top cover. Seems like a good use for the 3d printer.

Got a lot done.
Barrels modified, threads turned off, stainless bushing pressed on with Red loctite, worked out well. This was needed for interchangeable barrels / wedge mounting.
Bolt carrier done, did 2pc, with 2 dowel pins in the joint, did a 1 inch boss and pocket for alignment, milled the hex and then broached out the 4-5 thou in the corners remaining.
Box cam blank installed, screwed in. Stole the idea from someone on the forum, screw it in as one piece, later mill the groove and then the 2 pieces are all pre aligned.
Made a new cascabel back plate.
Made up a new front assy nut w/thrust bearing.
Reworked the DE equal to the cocking ring, hole cut for bolt installing, holes for cocking assy drilled. Because the ring is pretty thick, I put a ball bearing on the muzzle side of the plate and then the thrust bearing on the rear side. Thinned the plate a bit
Modified the DE large gear hub. Broached a 1/8 key slot in that gear hub and the mate on the mainshaft. This will give me about .150 adjustment room for headspacing. The gear/hub is a nice slip fit on the mainshaft with the key for driving it.
REMAINING: Bolts, cocking assy, cut slots in barrels for mounting wedges, make up the wedges, a lot of finishing touches like cutting the barrel slot for the extractors and such but hell by then I am home free.
I am tickled at how its working out. It rotates nice and smooth with the crank. The hex mainshaft is a huge improvement from the DE 3 pc design.
PS, the camera angles creates some illusions, it looks like the feedramps do not center on the barrel chambers but that is not the case. A dummy shell slides in every one without any binding or misalignment.

I have been a Mold Maker since 1966. I retired in 2000 and this my little hobby and I manage to keep out of trouble in.
