GBC instructions

Description

Build your own Great Ball Contraption from a single LEGO Technic set!

Here at Beyond Blocks we want to make your LEGO sets go further. We want you to use your sets again and again and learn as much as you can from them.

One thing that we are crazy about here at Beyond Blocks is the sub-genre of LEGO machines that move balls from one place to another, called GBCs.

LEGO fans the world over devote time and effort to building specialised mechanisms to move marbles, usually around a loop, and meet up to put their contraptions together into large loops that are just mesmerising to watch.

For a long time, GBCs were quite complicated to make, with GBC builders having to find special parts from lots of different places in order to make their modules.

That’s where our friends from PV-Productions comes in.

PV-Productions create alternate builds from popular LEGO Technic sets, so that you can start building GBCs straight away using a set you can buy in the shops!

We’ve built lots of PV-productions models and highly recommend them. Why not pop over to the PV-productions store today and see what you can build.
