It has never been easier to build a complete Great Ball Contraption (GBC) loop yourself! GBC 20 features a mesmerizing module which covers a full loop so the ball flow never ends. Using a more accessible LEGO Set and focusing on one single mechanism this GBC is by far the best GBC to get started.

This GBC is entirely built using only parts from the LEGO Mine Loader and can be referred to as model C of the 42049. This GBC makes sure you master the GBC building techniques and tricks so that you eventually also can build your own GBCs. The whole machine is powered by hand on default but can easily be upgraded with any LEGO motor (more information in the building instructions).

 

 

Master gearing & mechanisms

 

 

Learn about the wonderful world of mechanisms by building our GBC 20. The star of the show is by far the cardan gear mechanism which acts as a lift for the GBC Balls. The cart of the mechanism holds up to 2 balls and get filled by triggering another timings mechanism at the bottom. When filled up the arm of the cardan gear works it’s way up and drops them at it’s highest point. The balls will be catched and return to the base via the return path. By doing so the loop will never end.

 

Fun Fact


Designing a GBC from such small part inventory really took all the ingenuity and experience we gathered over the years. Parts are being used in a new way and many problems had to be solved for getting this GBC to work and making it sturdy and reliable. Using over 98% of the parts that come with the set we really did get the best and most out of the original LEGO 42049 set. There was a real challenge to build a GBC from such a small set but we succeeded again.

Power & Automate

Unfortunately LEGO set 42049 doesn’t include a LEGO motor. For that reason, the GBC 20 Mining Lift is by default powered by hand. However we designed pre-designed motor mounts so you can easily upgrade the GBC 20 Mining Lift with any of the LEGO Motors available and make it go on it’s own.
How cool is that!

  2. joopmelchers –

    Nice GBC, Only needs some finetuning in the end.
    Leuke GBC, ben nog bezig om hem goed werkend te krijgen.

  3. paweturalski –

    Very creative Timings Mechanism. Maybe it should becalled “Flexible Mechanism”? ? I have one important objection – setting arm can be a little bit harder for basic builders. Although it is well explained and everyone can build it. You have to perfect match every gear teeth. When you power it with motor without disabling direction lock mechanism this GBC looks and sounds perfect next to dial clock

  4. Thorsten –

    Thanks for the 42049 GBC! Great build! Also the communication and support with pv productions is just awesome! Got replies back on my questions in record time. Happy Holidays!

  5. Carla –

If you don't have the required LEGO set there is still a chance you can build our models by using parts you already have. Most technic models use a lot of the same and/or replaceable parts. When watching the video and checking upon the building instructions you can easily see which parts can be replaced if you desire so.
What cool color designs can you come up with?!
