3 Gear Trains

Do you have piles of pieces and parts and need a new project? This is a series of step-by-step building plans for three gear trains ( in order: 8:1, 9:1 and 125:1 reductions). Each gear train utilizes different gear pairs and can be integrated into a wide variety of projects. These fun models
can be put together very quickly. You probably have these parts laying around
the house. This is a great way to get the whole family building together!

Get a move on and start building! Another fine plan by Brick Banana!
