The roadwheels were boring but pretty quick, the individual link track however ...
1 Pick up a link, trim the flash
2 run a #72 drill through the four holes so the pin won't split them
3 clip link to link
4 run the drill through one side (see #2)
5 find the end of the pre-cut pin that doesn't have the bur (see #2)
6 insert pin through one side
7 run drill through other side (see #2)
8 push pin home
Repeat until you have 55 links per side. I did it in four runs of 19 and two of 17 simply
because 19 links in one go were the limit of my patience and longer runs put too much
pressure on the connection points. I know this because my first run was 27 links and it
flopped around and split out two links in the middle.
