So after some trial and error I managed to get the tracks going.
Started out by cutting some strips of .20 Evergreen plastic 1/8 wide and cutting those into pieces a 1/4 in. long. By stacking seven or eight at a time I was able to sand them all to the desired shape rather quickly.
Once I had twenty done I laid them out on some electrical tape using some plastic strip to line them up. Round plastic rod was shaved down on one side with a #11 blade. This was then glue to the links and allowed to dry over night.
The links were now cut apart and the edges were sanded with an emery board.
Now comes the fun part, each one was drilled out with a pin vise drill to allow the cable to pass through. In this case the ‘cable' was some heavy-duty thread.
I tried counting the links from some pics and drawings and it looked like there should have been 18 but when I wrapped it around the wheels I realized I was going to need 21.
Still have to do a little more sanding to round off the edges and then it's on to painting and the base.
