I would like to do a parallel build with one or more members, more is better.
Not the traditional RG-G design. More of a Rat Gat.
Based on the Ruger 10 22, with 5 stock barrels and bolts.
I picked up 5 barrels at a gun show for 10 bucks each and a bolt for 20.
There\'s a lot of parts out there.
Who\'s in ??

I am interested but just too involved with the firing problem of the D&E. I would like the opportunity to work with you. I will, however, follow the posts with much interest.

I\'m looking at this as a secondary build.
Maybe taking around 2 years.
If you have comments or suggestions jump in, I want different ideas.
Good luck with the problem.
And Thanks

The aluminum prototype bolt for the Rat Gat is almost finished.
The bolts will be 303 stainless.
Most of you will recognize the hardware.

The plate you made turned out very nice and looks great with the barrels in it.
Your Rat gun looks almost like about a .357 magnum size compared to the .22 next to it. That might be the way to go if we can\'t find any more .22 lr ammo. At least the center fires can be reloaded again.

cutter,
If you want to start a .357 with about six barrels, I would be right behind you also. The only problem that would need to be delt with is the recoil on the bolts would need to be absorbed 100% by something other than the cam follower pins or bearings.

The cams angle changes about 8° from 25° to 17° or
about 30% difference. Creating less friction getting to
the firing point, and smoother transition to the
recoil point.

300 rounds or 4 full magazines.
29 rounds did not chamber correctly, either fell out or jammed and bent.
But no misfires on the 271 that chambered.
Back to the drawing board.
Post by: bruski on January 18, 2015, 06:30:31 PM
Cutter,
Do the rounds get out of place from the recoiling? If so the only solution that seems to correct that on my .357 gat was to change the box cam to a steeper and faster closing speed. I tried adding a cartidge holder but wouldn\'t you know it the rims hung up on it some of the time. It has quite a bit more recoil than the 22 does though.

Post by: Cutter on January 19, 2015, 12:42:24 PM
The .22 is so light it doesn\'t take much to move it.
A little deeper in the chamber , before the recoil occurs makes sense to me.
A new Cam needed.

bruski
Post by: Cutter on January 24, 2015, 01:00:07 PM
First I created the cam in a wire frame, from predetermined points.
Next was constructing the surfaces from the wire frame.
Only the cam path surface is used for cutting on the CNC mill.
The diameters and length on the lathe.
This should chamber the round .220 deeper at time of firing/recoil.
Post by: Sparky_NY on January 25, 2015, 08:06:37 AM
Ok, I must be a idiot ! LOL All this talk of putting the round deeper into the chamber, and then Cutters cam that puts the round almost a quarter inch deeper at firing, what am I missing? The rounds rim has to be tight to the breech face (barrell face) and the bolt reasonable tight to the round (less headspace). How do you push a round a quarter inch deeper into the chamber?????? Tear the rim off? LOL
What the heck am I missing?
George
Post by: Cutter on January 25, 2015, 11:32:35 AM
Sorry George, my bad
The problem barrel is at 60° from TDC, at the time of recoil the cartridge is only .150 into the chamber.
At recoil the cartridge would sometimes get cocked in the pan, causing the problem.
I changed only the delivery side of the cam.
The path starts at 18° , at 60° the cam changed by .220 , then back to 150°
I need those 3 points to create the spline.
Post by: Sparky_NY on January 25, 2015, 06:38:55 PM
Ahhh now I understand ! I was thinking of the barrel that was ready to fire. Couldn\'t figure out why you would try to push a round .220 further into the chamber than its seated position ! LOL

Post by: Dave on February 20, 2015, 12:27:58 PM
I machine a lot of white delron... The black (to me) doesnt seem to cut so well....
Interesting part about doing that piece in two halves on the mill.... So did you just stop it half way thru and flip it or did you do it in the programing? I\'d like to know more!
Interesting on the Lego piece too! Legos are awesome!
Post by: Cutter on February 21, 2015, 10:25:59 AM
Cut half, rotate and do it again.
Post by: Dave on February 21, 2015, 11:55:33 AM
Neat, so do you just program half of it?
Post by: Cutter on February 21, 2015, 02:40:54 PM
I\'ve assembled and disassembled the gun many times in the last
two years, and I know there\'s more to come. The separation of gears has saved a lot of time.
This idea came from an earlier post by Jeff E
Thanks Jeff, and one program Dave

One of the guys bored the bolt carriers and
put in the slot for the drive pin, and I finished the
cartridge carriers and alignment holes.
Cartridge carriers are 303 stainless.
Post by: Cutter on May 15, 2015, 06:14:27 PM
I would like someone to do the lathe work on the bolts.
Here\'s what I\'m thinking,
Someone to supply material (303 stainless) and 58 bolts to this sketch.
In return you get both carriers, barrel plate, and 7 of the
bolts after they are finished on the CNC mill.
Open to questions & suggestions.
Post by: Cutter on May 28, 2015, 11:29:53 AM
I cut 6 \" off stock 10/22 barrels.
I\'m planning on exposed rotating barrels. ( no frame to the front )
Bolts are in process, still one slot open

( .4° taper per side )
Post by: Cutter on July 09, 2015, 05:09:53 PM
Had a little get together with some other builders.
And there\'s two more out there.
Post by: Cutter on July 15, 2015, 09:55:52 PM
to flip out the casing consistently, 75 times anyway.
I\'m also changing the drum drive gear, mounting gear segments on the bolt carrier
instead of the gear on the cartridge carrier.
Post by: gbull on July 18, 2015, 01:11:46 AM
Any hints on how you get the round to eject and jump off the bolt so neatly? I watched the video a bunch and I\'m stumped. Nice job!
Post by: DonLans on July 18, 2015, 09:01:14 AM
I\'m constantly amazed at everything Cutter does. Any chance of putting the Mars Rover pictures back up?
Post by: Cutter on July 18, 2015, 02:09:01 PM
I have the extractor rotated as far to the right as possible applying
uneven spring pressure on the casing causing it to flip out as soon
as it clears the chamber. My first attempt about three years ago
was with the extractor on top, but the even pressure would hold it in place,
sometimes release it, never knew where it would go.
Notice the slot in the original pan for a kicker, pan
is in 4 parts now. Works good, I\'m not changing that.

I have not worked on the mill in quite a while, I got the electronics done and the Z under motion, the X and Y remain. I got sidetracked ! I built a 32x50 pole barn for a workshop, 10ft ceiling. It was a lot of work and the end is in sight now, pretty much down to some wiring and pouring the floor. Gonna be a hell of a shop, something I have always wanted but never had the room. Meanwile, I picked up a jet 14x40 lathe a few months back, a big improvement from the 9x20 I had.

What kind of steel is your group using for such parts? The workmanship and finishes are superb !
George
Post by: Cutter on September 28, 2015, 03:12:49 PM
303, mainly because it\'s corrosion resistance.
There\'s a lot of rust out there
Post by: Sparky_NY on September 29, 2015, 06:38:23 AM
Ha yes, excellent choice ! Stainless gets rid of the rust worry and having to constantly clean and oil so the slightest fingerprint does not turn into a rust-print.

Here\'s a little information on the bolt.
The green point is for a 3/32 roll pin.
The firing pin slides under, taking place of the staked area on the original bolt.
The red point for the original 5/32 roll pin through the obround slot in the stock firing pin.

The post you did in that other thread, and the pic here got me thinking. One of the projects where I work is using all stainless piping for everthing. (paper mill). There are scraps around, small up to over a foot in diameter. I wonder how that would work for gatgun projects. I will have to look next time I am over there and see what the wall thickness is on the smaller sizes.
Post by: Cutter on October 12, 2015, 09:50:43 AM
The stainless pipe your referring to is probably 304 or 316
Not my first choice for material, free or not
It\'s only a hobby

One more thing. Do you not like the other grades of stainless because of how it machines? I have some various sizes of unidentifed stainless that I\'d like to use.
Post by: Cutter on October 20, 2015, 04:23:19 PM
joboxxer,
The stainless I referred to in an earlier post has
piss poor machinability , in the past I quoted those parts @
3 to 4 times that of mild steel. Also draws more blood.

To put things into perspective, how long did it take to draw that part up and how much machining time to cut it?
Post by: Sparky_NY on November 23, 2015, 06:01:07 AM
6000 hours of educational time leaning to drive the cadcam and the cnc machine, 10 minutes to draw, 10 minutes to machine LOL
Its the old story of how people with a LOT of experience make things look easy.

If supplied a 2D print it would take under one hour, but this
is all about what I want so I keep making changes.
I think one day for the machining process.

Great pictures. I wish you were in the Maryland area. I sure could use your advise on putting mine together.

For your loyalty I’m sending a free bottle of 22 caliber Gatling gun get-er done
secret solution.
Post by: Sparky_NY on December 16, 2016, 05:55:55 PM
I am hoping that secret solution is a minimum of 92 proof ! I won\'t make less mistakes, I just won\'t care.

You can\'t just post a pic like that with no details ! Inquiring minds want to know...... What are material are those mags made from? The black color has me wondering if its a plastic or metal painted / anodized or something. They look great, and function even better which is what really counts.
Post by: Cutter on February 05, 2017, 12:21:43 PM
The material is black Delrin, I use it because it’s black,
slippery, easy to cut.
I will make some drawings of the newest gun version, but very limited.
Beginning with the Bolt, In my opinion the most important assembly.
The heart of a gun, it does all the work.
Always open to inquiring minds

There are a lot of inquiring minds on this forum and a lot of frustrated GG builders. You give us all hope! Thanks for sharing your skills and talent.

Cutter is like a reincarnated Dr.Gatling to us here. Best is how he shares his work and is willing to help out others.

I’ve opened a new email account for my GG hobby.
For those interested email for the info, many of you have my current one.

I finally finished the magazines.
When the temperature drops below 50, I’m like a lizard.

Are those the ruger style extractors in the video? Does the gun also have the flat finger ejector? Sure works great !
Post by: Cutter on January 19, 2018, 09:07:22 PM
Yes sir Sparky, Ruger extractors.
No flat finger ejector.
A combination of extractor spring pressure and
modified cartridge carrier flips-em out nice.
Post by: Cutter on January 20, 2018, 11:18:14 AM
One important fact on the RG-G design is there is
no blowback , so the Extractor does all the work.
Get a grip..
