graucho--I spent 43 years working as a mechanical design engineer doing exactly the things you mentioned. I don't fish or golf, so when I retired last spring I decided to spend some time building a MB and now I'm hooked on it. All those photos you post are great motivation.
rawly--I agree, if it worked the first time, it wouldn't be worth doing.
One of my objectives is to make a MB that does not attract attention, so I need a quite muffler. I looked at bunches of automotive mufflers on the Internet and found one that looked like it could be scaled down. The body is 3-in dia by 9-in long. The inlet and outlet tubes are conduit. The exhaust noise is substantially reduced, but still too much mechanical noise.
Eventually, I will be trying to make an enclosure which will look like a trunk and hide the drive train as well as absorb noise.
I added a speedometer and took it out for another ride. In the middle gear it cruises easily at 22 mph, even up small hills. In high gear it quickly got up to 26 mph, if the road was longer it would have gone a bit faster.
I will be setting this project aside for awhile. But, will definitely have more to post before spring.
