5 silver spacers
16 blue spacers

4 blue slot connectors

Step 1: The Main Box

for this step you must make the main box that holds the gears together.

Step 2: The First Gear

This is the first gear with the motor attached to it.

Step 3: The Second Gear

this is the second gear to be made which has the actual handle to change gear.

Step 4: The Third Gear

This is the third is the last gear to make.

Step 5: Putting the Final Parts Together

    Please please please can you make a video of it working!

    I don't get how you switch gears.

    Also can you add a clutch.

    nice; i like it, i just came here to ask if anyone could help me encasing my transmission plz;

    This is a very good instructable. It works well. Just so everyone can know, a silver spacer is the same as three blue spacers. I really like this. the only problem I have with it is the fact that the pictures exclude some parts (the corner of step one) but all else is good

    Bravo! Sherlock.

    Well maybe some people don't know that a silver spacer is equal to 3 blue spacers. Don't give negative comments to people who are just trying to help out. not all sets include the silver spacers. next time, think before you speak.

    How is it negative? I was just congratulating you.

    usually "Bravo! Sherlock" is a term used when someone states an obvious fact. That is negative.

    Sarcasm much?

    BRAVO. WORKS WELL. CAN YOU TELL ME HOW TO MAKE IT FASTER?

    are the blue gears and the golden gears the same because i don`t have any blue gears

    yes, but they are a little loose. well at least mine is. the little grey ones won't work because they don't have a place for the tan pieces to go into

    i made this then did something similar with 3 speeds but it has no neutral

    the offspring is the best band in the world

    It's a motor from the knex amusement park kit with the 3 ft tall ferris wheel

    OH I HAVE THE FREEFALL ONE

    you made mistake in parts list: it is not 7 blue rods, it is 9 blue rods
