Hi guys, I haven't posted much lately, I needed a break from all things AR related for a while. I have been working on a retro project that some of you may be interested in though. These parts are the bolt carrier block, rear barrel plate, and bolt blanks for my .22lr, 1/2 scale Gatling gun project. I have a long ways to go to finish it let alone a carriage for it, but it'll be a blast when it's finished. I will get back in the retro AR game soon.

If I can find 1/2" stainless tubing reasonably priced I may even do the barrels in stainless.

VERY cool. Great work. I knew someone "back in the day" (1990ish) who started a .50 cal minigun project. He started with a demilled 20mm vulcan mini and was going to make 50 cal inserts for the barrels. SUPPOSEDLY he was building it for Stembridge prop house. He ran afoul of the Feds on another front, though, making M60 receivers and M2 50 sideplates.... Lost track of him after that. The one time I saw it, it was partially together and he was trying to turn down M2 barrels to make chamber inserts.

I can't wait to see this project finished. Doc Even with the hand crank, 50 rounds is only a 5 second burst. If it were legal to put a motor on one you'd still have to keep it down to around 600 rounds per minute and need a big drum or some sort of belt to feed it. I'll be happy just to get all ten bolts feeding, firing, and emptying the barrels reliably. |

Parts is parts. This week I machined the elevation wheel, bolt extractor knob and shaft, cocking mechanism knob and shaft, the main shaft nuts, and the cylinder with the paper template taped to it will be the box cam when it's completed.

http://i98.photobucket.com/albums/l260/my65pan/rgg.jpg Lemme check around our shop... How much do you need? And what exact ID / OD? At worst it would be 316 stainless. Is that acceptable? I work with hydraulics in the marine industry and my boss is a hoarder. 
Not quite a gun-nut yet but I'm getting him there... His wife's chinese Pardner Pump 20ga is slowly morphing into a K.I.S.S. home defense weapon.

If you're going to the trouble of doing barrel inserts and what not why not make them out of aluminum and then anodize them glass black?

It doesn't look like much, but these little parts weren't easy to machine. It's the cocking mechanism, the two tall ears will take the recoil as each bolt passes by and fires..

I'm using whatever brass I can scrounge right now
, but I put in an order for some tubing for the breech casing etc. and some rectangular stock for the side rails and magazine base.. Machine marks are easy to smooth out on brass. I was going to go all stainless, but I can't find stainless tubing in the correct diameters for what I need. Brass and stainless will look nice though I think.

I decided to mock up some of the main components I have done onto the bar stock blanks I have for the side rails, I put the Coke can in to give you guys a visual scale. The coolest thing about this project for me is that my son has started to show an interest now that he's seen it go from just a bunch of drawings on paper into actual parts that resemble a Gatling gun.
I don't want him to be a machinist for a living, but I hope he takes an interest in operating machine tools, fabricating his own stuff, and doing his own repairs just for the satisfaction, and for the fact that all of my equipment will go to him some day.

But, don't you think solid gold will wear really quickly? I know I said I was going to have very little brass on it, but I've had better luck finding what I need in brass. Besides, it'll look more RETRO this way. Do any of you guys have experience using silver solder? I need to learn how to do it, and what solder, flux, torch, etc. is recommended for hard soldering brass and steel. As a side note, I've decided to build a scale replica Civil War mortar once the Gatling is completed. I haven't decided on golf ball scale or soup can scale yet though. While I was searching for plans I ran across a guy selling plans and material for .177 caliber black powder mortars. I took a little time to machine and assemble it today. Now I need to find some firecrackers to steal the wicks from.

The breech casing is done, along with the magazine base you can see to the left.
I spent quite a bit of time on this fixture and clamps. I'll use it to mill the cam track for the bolts in the box cam, and locate and drill the mounting holes to fit the two halves to the breech casing.
