Michael, thank you. Had to whip out the optivisor for sure with all the small parts.
Halfway there, I think 9 hours one track.
Pretty impressive with the quality engineering & design. This is the only set of injection molded plastic tracks, I’ve seen that flow and move like high quality 3D printed or white metal.
However, they are fragile, just check out how little of that pin circled in blue on the left can engage with the arttached link.
To the second track…
