Anyone have plans how to make a tipping metal bucket for a water fountain.
Where the bucket fills then spills into a lower body of water then rights
itself and does it all over again ? Jim

Well, you just sort of set it up so that the center of mass is below the
pivot points when it is empty and above the pivot points when it is
full - then it goes unstable, tips to dump the water then is stable again
in the upright position.

True, Mikey, but put the pivot point a bit arrears of the direction you
want it to tip...... If it's centered, it could go either way!

True, unless you do like a lot of things I have seen, you build it with a
stop that only lets it go one way. But, you are right, you probably
want to make sure it tips the way you want it to go (unless, maybe
you want it to be able to flop both ways) ;-)

Thanks for explaining why I tilt over and "faw down" after filling up on
about 12 beers. G

As uncle Frankie used to say when working outside on a hot day,

"Six beers before twelve and twelve beers before six"

And you don't want to have good bearings in there or the bucket will tip as
if fills. Better to have a little restriction in the form of a wiper to
provide a stop til the bucket gets a bit further into the overfill.
You don't need much of an offset and if the bucket wants to go the wrong
way, turn it around.
Might be fun to see a series of buckets that feed each other in a triangle
and figure out which one si going to be next. If you do a good balancing at
the beginning, it may last for a while.

Even more entertaining could be a bucket mounted on top of a spring
so that you never know which way it will tip ! (sort of look like a tulip).

Wellington has a bucket fountain which has been something of a tourist
attraction for the last 40 years or so. It's a stack of bistable buckets, small
at the top graduating to large at the bottom. Every few years the sealed ball
bearings on the bucket pivots get replaced. I can't understand why they don't
use delrin bushes, it seems like an obvious application. Maybe that would be
tampering with a work of art?.

Hey Jeff,

Try to keep this guy from being so "tipsy" he falls over. Enjoy!

You just move you mouse left to right (no clicking) to keep him
walking in a straight line. The object of the game is to keep him
walking, without falling over, by using your mouse from left to right
or right to left. Sounds pretty easy, BUT... you can't see the mouse
cursor, which makes it quite difficult.

Apparently the record is 82 meters! Best I got so far is 72. It's in
German, but it doesn't matter . CLICK ON THE LINK BELOW TO PLAY - IT'S

Take care.
