TLCB’s Lock-down B-Model Competition is go! The first of several entries to share today, this is Clemens Schneider‘s spectacular bucket wheel excavator, built solely from the parts found within the 42097 Crawler Crane set. With a rotating superstructure, working tracks, a hand-operated boom winch and bucket wheel mechanism, Clemens’ B-Model has as much going on as the set from which its parts are sourced. Best of all, there are instructions available too, so if you wish to convert your own 42097 set you can! Head to Clemens’ photostream via the link above for all the details, and if you’re stuck in lock-down with a LEGO set available, build us a B-Model like Clemens and you could win an SBrick pack!
