For week #6 the Dacta 1030 / 1031 set brings us an exercise on using gears. This particular exercise looks like a simple constructions, and well the two models you get instructions for are pretty easy.
However the two models on the back of the card are a little more complex to build for those not used to working with the smaller gears. Sorry no instructions for the additional models but each is easy enough to build from the provided pictures.
Here is the inside of the card #6
And now a quick picture of the first model, which demonstrates the basic interaction of two gears of the same size.
And the second model from the inside of card #6 which demonstrates the interaction of 2 large and 1 small gear.
And finally a short video of one of the models from the back of card #6… sorry this one came out a little darker then my last one.
