Planetary gear

[J. Tranter]

So thinking ahead for a future project, I have a set of small planetary gears that I pulled out of a cordless drill. Now I need help trying to figure out what to do with them.
So come on guy or girls give me some ideas.
I also have a 80 tooth and a 71 tooth gear that came out of there also.

All ideas welcome.

How about a model differential chain hoist?

Somebody sit a large anvil on that man - he'll be talkin' about Mars Bars next!

How about a steam powered vehicle with treads? Use the planetary set to drive through a differential with brake steering. It would have to be radio controlled. Kind of like the guy on Crabfu website. Looks like that would be fun to design and built.

Wouldn't have to be RC. Here's one that just uses a wire. Of course, it uses two electric motors and no differential, so a planetary gear might not be applicable.

I have a set from a drill too, I was planning to build an overbalanced wheel like this one;

The motor gears and batteries are hidden in the shaft so it appears that perpetual motion has been achieved.
