Introduction: Knex Manual/Motor Gear Box

Step 1: The Base

Yeah, everything else goes on here.

Step 2: The Motor

This section is the motor.

Step 3: A Bit of Support

It's easier if this is just an extra step. If not the next step is too long.

The added pieces in this picture are: 1 green rod, 1 white rod, 1 blue rod, and 1 yellow connector.

Step 4: Moving Gear

This gear shifts forwards and backwards to mesh with either the motor's gear or the manual gear.

Step 5: The Manual Gear

If the motor jams, switch to this.

Step 6: The "output" Gear

The rod is what to connect the turning part to. It could be any size.

Step 7: How to Use (you're Done Anyway)

With the motor facing towards you, if the trigger is left, turning is manual, if the trigger is right, then the turning is motorised.
