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.
