What to do with Ball Bearings? Answered

For some while I've had a pile of ball bearings sitting here on my lounge room table, and without knowing what on earth to do with them, I now ask you. I have found uses such as adding to my "mousetrap racer," a small car, run by a mouse trap, that can go up to 15 metres. With ball bearings it goes twice as far as it used to, so I have become curious... what to do now though? All ideas would help, and an instructable would be even better. Cheers

I take old ones and take out the balls and use them for sling shot ammo

Do tell, first I heard of it being a Fiat... I'm guessing a Cinquento... I think that's spelt right... Or a 500? it'd be cool to see an electric abarth 500, you'd probably be able to improve on performance too...

OK my guesses were a bit off, now get a beefy motor in there, the added weight of the batteries over the rear axle may improve handling to an extent, though too much without compensation will make it a bit of a handful...

Were getting a nice warp 9 motor. We plan on beefing up the shocks if we can.

How much power? Whatever you say go get something with twice as much. Consider it necessary, think you can get there twice as fast, so you'll have time to recharge when you get there...

IDK. I'm just working on it, I don't get to make any purchases. I'll adjust the controller once we order it. Muahahaha!

you can easily double the quality of the finished product with a toggle switch that has the options: Magic/More magic

Hmmm.well first you would need to make the two sides and a middle: ()-(). Then put the ball bearing on the middle bar : ()=(). Just add string!

If they're heavy duty enough you could make yourself a bed on cantilevers and gently rock and swing while sleeping, then flip it up or down out of the way when not in use...

Err, yeah, great idea but when they're 3 mm wide and look as though they'd break if you stood on one, they wouldn't be much good for that, thanks for the idea though!

they look like skateboard bearings to me, so they probably wouldn't break if you stood on them.

if you have a slingshot take them apart and use them as ammo u know the steel balls

The steel balls wouldn't be a millimetre across, and my slingshot doesn't take things that small. Thanks for the suggestion anyway. :D

use between pieces for "lazy susans", or other turntables, etc

Lazy susans? I don't believe I've ever heard of one of them. Could you please explain? Thanks!

As GH said, it's a turntable - the kind of thing you put in the middle of a dining table so that people can turn it to reach all the serving dishes.

Yes, or you can use them in deep cabinets so you have instant access to things in the back (just spin the turntable about and it comes to the front :-) Examples follow...

Hi, don't worry I got it. I've seen the ones that you set in the middle of the table, and I've even got one of those set in your cupboard! Just goes to show, look around the house if you want ideas, Thanks!

Mouse / rat wheel?

bearings for a wind turbine, water-wheel etc?

Make a model of that big wheel they use to choose prizes on The Price is Right?

Hmm, I do believe the wind turbine idea would be rather fun! ...errr... I haven't ever really done much with producing electricity, I know how it works and I have run a small LED of a motor that I cranked by hand, but any ideas on storing this energy? An example schematic maybe? Of say a wind powered light with a switch, and doesn't have to be spinning to run? This would probably help me get my head around it. =S

Storing? Only two real options: rechargeable batteries or super-capacitors.

Schematics? Search the site - there are loads of turbine-related projects, from small ones to blink LEDs to large ones to take your house off the mains grid. Just search. If none of them are to your taste, search the web for picoturbine - scaling that project up will charge batteries quite nicely.
