Lego Technic Set 1030 / 1031 – Week 9

Sorry just a little late with this week’s Lego Dacta 1030 / 1031 write up.

This week we look at instruction card #9, which demonstrates the use of gears and leverage to produce circular motion.   The card gives us 2 models, the first is a simple lever action that drives a fan.  The second is a oil or gas well pump you would see out in the fields.

The instruction for the build are simple enough and the produced model works better than expected.

And the built model……

… and a very quick video on how it works.

The second model, is that of a gas or oil pump you would find in petroleum industry.  As this this model is found on the back of the instruction card in the form of a picture there are no instructions, but it only took a few minutes to figure out how to build it.

Well that’s it for this installment, Ralph.
