Has anyone used the Tank tracks (429139) from Lego education set 9648 for anything other than a tank?

The tracks are fixed in size, and I've found the application rather limited (driver belt, track) so far.

At this stage they seem to be a bit of a novelty - so any feedback welcome!

  • I couldn't find the part '429139' in that set, are you referring to this piece? – Ambo100 Sep 15 '17 at 20:02
  • I was suspecting part 57518 was what they meant, but it is not clear. – chicks Sep 15 '17 at 20:35

    @chicks I couldn't find those in the set referenced. – Ambo100 Sep 17 '17 at 12:53
  • Yes, that's the part... the set is a LEGO education set - not sure it the part numbers differ as I took it straight from the included part sheet. – Nita Sep 21 '17 at 7:13

My FIRST LEGO League team likes to use them as clothing accessories, like belts, headbands, sashes, etc.

More commonly, though, they are used for conveyor belts (for example, in a great ball contraption). You can also use them for a chain drive when 3711 is not strong enough or big enough.

I also saw this recently where small carriages were attached to the links and it was used as a vertical parking system for matchbox cars.

    +1, threads like these are used all the time in GBC modules. Although not as versatile as Technic Tread Links they are slightly smaller in width which could be an advantage for smaller models. They can also be used as conveyor belts as shown in the Toy Story set Trash Compactor Escape – Ambo100 Sep 15 '17 at 20:08

I think someone years ago use them for a machine gun design that actually worked, they placed shooting pieces upon the track and ran it through a special gear worked mechanism that pushed the triggers on top of individual shooters, I think it could fire over 500 a minute, not much of a range but it did look pretty good fun. (forbidden lego of course!)
