Here's a shot of an axle mocked up.
The geared wheels took about an hour to route (times four) while the plainer wheels took about forty minutes each (times twelve wheels). There are sixteen wheels in all. Today I finished the train wheels and started in on the wheels for the log car. While the MultiCam was busy I fired up the welder and began work on the train engine frame
There is still a long ways to go but it is coming along nicely.
