Introduction: Knex Cable Car

This is a small machine I made recently. Its a cable car that rides on a long piece of chain. Nothing too phenomenal, but I hadn't posted anything in a while and I thought some of you may like it...

Enjoy!

Step 1: List-o-pieces

Well, although the piece list is very small, I thought I'd make one anyway. Woot!

Rods
Green - 32
White - 34
Blue - 10
Yellow - 4

Connectors
Green - 16
Yellow - 14
White - 6
Blue - 4
Purple - 4

Other
Chain - as much as you have. I used about 40 feet.
Red Gears - 6
Yellow  Gears (photo) - 2
Tan Clips - 16
Blue Spacer - 12
Silver Spacer - 4
Power pack motor - 1

Step 2: Gear It Up

This is the step in which you will make the gear and axle assemblies that will ride on the chain. Get to it!

1: Make this. The tan clips/spacer are identical on the other side
2: Build two
3: Now build this
4: Another view

That's done. Keep going!

Step 3: Not the Guts (the Sides)

These are just the two side panels. Easy!

1: BUILD IT
2: ALSO BUILD IT

Done!

Step 4: Make It Pull Its Own Weight

...By making the motor assembly.

Build this by looking at the three images shown.




Step 5: Assembley

Time to put it together!

1: Snap in the motor assembley on to the two yellow connectors like so
2: Another view
3: Slide the gears into their respective holes
4: Another view of that
5: Feel free to wrap up the extra cord around that blue rod
6: Slap the other panel on to finish it up!

Step 6: Don't Not Set It Up

Time to set it up!

Find two objects that are just slightly closer than the length of your chain. Hammer in a nail, and place the chain on it like so.

Make sure the chain has no twists or broken links (photo 3). This can cause the whole thing to break.

Unclip the chain, slide it through the car and reattach it, and presto! A cablecar!

Step 7: Done!

You're all done!

Thanks very much for viewing my instructable.

Is it possible to use a micro-chain?

author

Oh, shoot... I guess you can't.

get an old fasiond touch one then add a rod to the front with duct tape get solar power motor the get it going towards thelamp it should touch the lamp shut the lamp down therefore shuting its power source down so it cant move.

author
I_am_Canadian (author)knexjay2009-12-03

Try saying that again in english, and you'll get an answer.

author

 I think I might know what he means... He's going to make a cable car to turn off his lamp at night, but he's not sure how the car is going to turn off by itself. Kinda lazy IMO.

author

Ah, thank you :-)

Now I wanna make one!  Then again, I don't have a place to put it.

4.5* btw.  Oh and I think your cable car would be better if it ran on string.  Most people don't have a bunch of chain links.

author
I_am_Canadian (author)DJ Radio2009-10-19

I'm a purist :-p No string!

LoL, I've made them with string in the past... Perhaps a new project in the blueprints...

author
Kairah (author)I_am_Canadian2009-10-24

Nice and simple design!
I made a cable car some time ago... It went on a string AND solar power :P

author
I_am_Canadian (author)Kairah2009-10-24

Thats awesome! I wish I had one of thems solar motors...

author

I have one but I can't get it to work. I know you don't have one, but any ideas??

author

For what?

author

To get the motor to work.

author

What do you mean? If its to weak... I geared it down 3 times from small blue gear to large yellow in my cable car.

author

I mean I can't even get it to turn on.

author

 Just put the power cord in the motor and the other end in the sun panel. Then put the motor rod on the motor and it should start spinning with enough light.

author

Can it run off a regular light bulb??

author

No, it can't. Unless the lightbulb has electrons and photons coming out of it. Otherwise, the solar panel cannot create energy because it runs on those 2 elements which comes from the sun. (I think...)

author

Yes it can. Trust me, look at my alarm clock, it can run off light bulb.

author

Lolz. I made that the other day! I put it under lights and it doesn't work because mine are fluorescent (they don't give off energy). Then i brought it outside and it didn't work because the solar panel does not create enough energy to power the motor. If it worked for you, then take your cable car with the solarpanel on it with the motor and use the same light and light bulb and try it.

author

Was the panel in direct sun light?

author

Yes it was. I checked to see how much electricity was coming out of it, there was some but not enough

"Nothing to phenomenal," shouldn't that be "Nothing too phenomenal"? :)

author
Lowney (author)I_am_Canadian2009-10-24

 Are you gonna change it?

author
I_am_Canadian (author)Lowney2009-10-24

That is the question.

author
Lowney (author)I_am_Canadian2009-10-25

 Ah yes but what is the answer?

author
andross52 (author)Lowney2009-11-23

 42.

author
I_am_Canadian (author)Lowney2009-10-25

Nah.

author
Lowney (author)I_am_Canadian2009-10-25

 Why not? 

author
DJ Radio (author)Lowney2009-10-29

Because nobody else cares.

author
I_am_Canadian (author)Lowney2009-10-25

Because a miniscule grammatical error is not nessisary to change - these things take time.

author
Lowney (author)I_am_Canadian2009-10-26

Wha? It takes like 5 seconds to change! For me it does anyway. 

author
I_am_Canadian (author)Lowney2009-10-26

Think of all the things one could do with 5 seconds...

,,Fine I'll change it,,

author
Lowney (author)I_am_Canadian2009-10-26

Victory! :D
You did the right thing.
