A dish would look more original but for your application would really serve no purpose. It's done to suppliment weight. When the wheels have weight added to them they straighten more. You can make your spokes at a slight angle. That's how the wheelwrites do it. The spoke itself is straight, it's the part that goes into the hub that is angled just a touch.

Bolted hub wheels are a hell of a lot easier to make too cause you can set all of your spokes and not have to screw with the hub. You just put the 2 halves together after you have the spokes set and presto! Deffinitely the way I would go.

You can see the wood hubs i made but i am not happy with them. I cut the metal bands a 1/4" under size but the wood still shrunk over the winter. I know the metal would be easier to make work.luckley a friend had some 6" round stock he gave me to make the hubs.EPPS

LOL!! Great vid! Bet you don't get bit by skeeters when you fire that beast.

Don't worry about your gun looking odd with bolted hubs. I made a 12 gauge gatling a few years ago and I used bolted hubs and thought it looked alright.

A pix of the chambers. I used shot gun primers instead of musket cap. A lot easier to make and much more reliable. One spare firing pin and the hopper.

EPPS, The wheels I made were 44" and had 3-1/2" by 2" felloes. I made the wheels to look like they had 1/2 moon felloes but in fact were 4 piece felloes. I put the felloe joiners 180 degrees from each other and butted the other seams together so you can hardly tell they are apart.I bought the felloes and spokes already formed. I had to cut them and tennon and drill holes, but the wood was already formed. I also found out (the hard way) that it is a hell of a lot easier to set the spokes in the felloes BEFORE you bolt the hub together. DOH!

I thought your gun fired regular cartridges untill your last post. You really did make this like the first original gun. Did you have any issues with gas leakage? I could see by the video that you had some leakage but did it cause you any problems? Gatling's first guns gave him problems because of this. Looked like it functioned great.

AS LONG AS THE CHAMBERS ARE ABOUT THE SAME SIZE,[ LONG] WITHIN A FEW THOUSANDS OF AN INCH THE GAS LEAKAGE IS NOT MORE THAN A REVOLVER. i SHOT ABOUT 250 TO 300 ROUNDS AND NO PROBLEM, BUT A COUPLE OF FIRING PINS BRAKE. i THINK i GOT THE FIRING PINS WORKED OUT.

Cool build. Does this gun fire at just past TDC? I'm trying to figure out the firing pin cam track.

It fires at 1 O'clock position. you can see the drop off for the firing pin cocking pin on the cocking cam. It has a small cam that pushes the chambers up against the barrels at the same time it fires.

Thanks. I thought that was what was going on. I had a little free time this afternoon I went and looked up the original patents. Pretty cool stuff there.

How do you load the round ball to stay put till it is fired? You have a great looking gun. I'm building a RGG 22. Does your RGG shoot well?
Thanks Bill

The round ball or mini bullet is load in the chambers with a wage fit. the chamber are taper reamed to wage the ball or mini ball in it. I modified a shot gun reloader to reload the chamber.Mac 600 jr.

I just bought the book you have in the picture ( The Gatling Gun Notebook). Are your barrels rifled? It is apparent you have put a lot of study into this gun.

Thanks Dave, The carriage painted OD green , just like it would have been in the civil war. the RGG is a little to small for this carriage, extra heavy duty.
