knex transmition that has neutral first and second gear and its my first Instructable

it has
1 motor
3 red gears
3 blue (and i have one gold) gears
2 two slot connectors
5 silver spacers
16 blue spacers
4 white connectors
6 tan connectors
8 purple slot connectors
4 blue slot connectors
3 red connectors
6 green pegs
8 white rods
1 yellow rod
7 blue rods
1 red (or green) rod
1 grey rod
total=79 pieces

Step 1: The Main Box

Picture of 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

Picture of The Second Gear

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

This is the third is the last gear to make.

Step 5: Putting the Final Parts Together

This is the final step where you put everything together.

It should be very fast in second gear and slow in first gear to make first gear slower and second gear faster take out the final gear.

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;

Rockrox (author)2009-12-13

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

Owenmon (author)Rockrox2010-01-02

Bravo! Sherlock.

Rockrox (author)Owenmon2010-01-07

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.

Owenmon (author)Rockrox2010-01-07

How is it negative? I was just congratulating you.

Rockrox (author)Owenmon2010-01-07

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

Owenmon (author)Rockrox2010-01-07

Sarcasm much?

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

knexfreak93 (author)2008-08-12

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

Rockrox (author)knexfreak932010-01-07

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

husbag3 (author)2009-12-06

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

ojochris (author)2008-07-18

does it have to be that motor? (i dont have 1)

You can use any. Except for the TINY grey motor.

robocrazy155 (author)ojochris2008-08-13

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

OH I HAVE THE FREEFALL ONE

feralin (author)2009-05-19

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

feralin (author)feralin2009-05-19

and instead of 6 green pegs you need 7

feralin (author)feralin2009-05-19

and instead of 1 green rod you need 2

feralin (author)feralin2009-05-19

and instead of 16 blue spacers you need 18

Jamese123 (author)2009-02-08

Cool

Tmbo17932 (author)2009-02-07

I have added this gear box to a knex car!!!!!! Check it ouT!!

Binnayy (author)2009-01-04

Is good (:

not-killerk (author)2008-12-25

This is a good idea, but from what i can see, it looks like you would have to go, neutral, high, THEN low. still great design though. amazing. if you could swap the gears around, it would be more like a real transmission.
EDIT---------
Never mind, it would depend on which shaft you apply the power to xD

Knex Rules (author)2008-12-06

Very good model, nice idea. After i made it i had a good idea where you add large gears and small gears to a right combination like gear 3 of this model till the last gear went extremely fast. Then, the speed which I had added had gone up by so much i thought couldnt this create unlimited energy, as in you collect the energy produced from the last gear and use it to power the engine, and use leftover stuff as free energy? Hope that makes sense.. but if anyone could help itd be great. I know my names crap but i couldnt be bothered making a new account (:

DrWeird117 (author)The Jamalam2008-08-24

oh. remember kids, ROCK LOBSTA!!!!! ¥ yeah, its a lobster

knexfreak93 (author)2008-07-23

Can you substitute the red gears for yellow ones.

Jamese123 (author)knexfreak932008-08-12

yes i tested it out

pyro-jim (author)2008-07-11

great instructable! I made on with a few adjustments and theres only one problem. When I change gear some of the gear line with the lever on gets left behind so i have to adjust manually withut the lever

Jamese123 (author)pyro-jim2008-07-12

try putting a tan connector on the other side of it

I_am_Canadian (author)2008-07-07

Really nice! 4 stars

hey "I am canadian" did you ever think that this could be used for a rc (roller coaster) chain? HE DISERVES 5 STARS!!! ya here me? no ones ever thought of this!! 5 stars on this acount and on my other acount, that i abandoned bcause i didnt like my user name anymore, i give it 5 and i'll get my friend to give it 5 stars to!!!! gr8 job jamese!

Hmm.... Mabey 4 and a half.. Buy i have my reasons for that rating. And how could this bu used on a roller coaster chain?

Jamese123 (author)I_am_Canadian2008-07-11

By putting to red gears on the end and joining it up to the chain before i make my car with this inside i will make an instructable on putting them on.

I_am_Canadian (author)Jamese1232008-07-11

Couldent you do that with any other old gear ratios, instead of having it on a transmittion?

transmittion = adjust to slow or fast; gear ratio = slow OR fast
