Lego GBC jigsaw

This is the last GBC I´ve created.  The first person who did it was philo. Although I have not found more than 10 models of the jigsaw in the net, so I set out to do it.

It is a robust GBC, consisting mainly of yellow, black and gray parts. The system transmits the rotation of the power functions medium motor is very simple. It has only 4 gears with 24 teeth and one of 8 teeth, as you can see in this photos:

The hopper is the same of the GBC ball pump:

Finally the last photo and the video:

    i think that the movement should have been a little slower.

    i really like this model,and found philos MLCAD model to be very helpful.

    a question: why did you use a crown gear (3rd picture) instead of a regular 24 tooth?

      Thank you!

      Initially this GBC was going to be very similar to the philo’s design. If you check philos jigsaw photos you can see how is conected the motor to the jigsaw. It uses that gear.

      The speed has no problem! I use a lego regulator so I can choose the best speed for it. Between speed 3 and 5 it works well. In the first speed it is too slow, and the last speed makes the balls jump. (I think this is the way to explain it: sorry for my misspellings 😦 )

    Yea i understand what you mean.
    insted of 1:5 you used 1:3,because the 1:5 was too slow.

    are you going to create a GBC loop? (with more than 1 model)
