How to make a bike gear clock. Simple and quick, I used the ReadyMade Magazine clock kit and old bike gears and a chain.

-old bike chain
-old bike gears, more holes the better
-Clock Kit ( I like the ReadyMade Magazine Kit)

-Chain Tool

Step 2: Lay it out

So lay out some gears and make a cool pattern, or a boring simple one Like I used. Then line your chain up and see if will look work out.

Step 3: Rosie the rivetter

So now, rivet the pieces together, If you have gears with holes, or cut outs this will work much better.

Rivet a few pieces together and make sure things still line up and look good.

Step 4: Chain it

Now lay your chain out and make sure it will fit together tight. In fact if you can get the rivet in the right spot you can use your gears as a cam to make the chain tight. Put it together with your chain tool.

Step 5: Put the clock kit in

Put the clock kit in to an open space in the gears and hang it up on the wall.
Take a look inside, it's my clock in a box! (clock in a box!).
My dad cycles, and i've always like this instructable, so I think i'm going to make it for his present this year!

So the gears aren't actually moved by the clock?
That's what I just realised. It would be way cool if the gears turned, but perhaps the clock motor wouldn't be powerful enough.
get a a motor with more torque

anyone else think that looks like a MAKE ripoff?
Aren't most things here like that?
i mean the magazine that this article links to

Actually the magazine is older than Make. Its less tech and more crafty. Its sort of a mod livin' on a budget magazine. But its pretty neat. -Joe

ah interesting, will have to check it out then
I love ReadyMade, but the clock mechanism is pretty overpriced at $14. You can get atomic clock movements for the same price here.

Or, if you live near an IKEA, you can pick up a full clock for $3. Then you can easily rip out the clock movement for a DIY project and have a plastic dish left over for a bird feeder or something.

Good call, the first clock I made used the movement out of a cheap office freeby clock.

The hands should be chains. Or have chains painted on them.
