Caterpillar tracks - Work in progress

10/8/2016 - demo of my completed prototype https://www.youtube.com/watch?v=2L4LVY-RTuY new files coming soon.

30/7/2016 - Added assembly video for track segments https://youtu.be/RxB7USuMwRw

28/7/2016 - Update!
- Fixed measurement error in chassis part (it was 5mm too wide D'oh!)
- My assumption about the Gearbox axles stripping the small hex holes in the drive wheels was correct so the solution is a Hub that will attach to the axle with grub screws and then slot into a much larger Hex h
