In this final set of builds, the models demonstrate how a basic rack and pinion steering system works using gears and axles. The first model is stationary, the second which is featured on the back of the card is a simple but effective little car. Only the first model has instructions, so a little reverse engineering is needed to build the second.
Here are two quick pictures of the main model.
And here is the back of card #20, as I need to get the house ready for winter I could not get to this one.
Here is a link to this week’s instruction card (PDF file) Dacta 1031 Card #20. See you next week for Dacta set 1032!
