Back on January 28th of this year, I drilled four shaft adapters for the drivetrain and dome drive. Two of the adapters turned out fine, but the other two had holes that were a little off-center. So early today on the way in to work, I went back to Industrial Metal Supply and purchased another foot of 3/4" diameter steel rod. I had them cut as many 1.25" sections as possible (9) for the shaft adapters.
They use a humongous band saw to cut the steel rod.
Now I have a lifetime supply of raw material for shaft adapters for my drivetrain and dome drive.
In the afternoon, I went to my friend-of-a-friend's machine shop to have the wheel housing of the drivetrain cut and milled.
First, they calibrate the CNC machine so that the 1-3/8" diameter hole will be exactly where it belongs.
Then, a big bore starts drilling the hole.
After all the holes were drilled, they milled out the slots on the top that will allow the chain to be tensioned.
When I got home, I found that the slots on top were just slightly too close to each other, so I had to file one of them on each wheel housing to widen it slightly.
Everything seems to fit as far as I can tell.
I also tried out one of the foot shells to see how it would fit, and it also seems to be in pretty good shape. I will need to file the channel area on the foot shell a bit lower to match the drivetrain channel, but I already planned on doing that.
Finally, I bought this today, whatever it is.

Victor, Can you tell i am doing battery research?? What is the conditioner for?
Mike told me to get this for the remote control transmitter and receiver. He says he's been going something like 3 or 4 years on the same rechargeable batteries. The remote comes with a charger, but apparently this one is superior.
