A Margraf clock - Brian - 11-27-2013
The time has come to think of the next clock, and i am getting the hankering to make another rolling ball clock, having built two Congreve's I want something different.
In1595 Christolf Margraf clock maker to Rodolfo 3rd in Vienna, made a clock that had a fixed inclined plane with a zig zag track and a lifting mechanism to return the ball to the top.
So using this basic idea I have started a new design, it's in the scribbling stage just now. so watch this space.
If you don't know the Congreve Look on My Site ( see bottom of the page ) for the slide show.

Brian,
I had a hair brained idea for a clock the other day, something powered by a fuel such as propane. A small enough impulse could be used to push a pendulum, or a larger one to wind a mainspring. Seems like it would be a fun hybrid project.

A long time ago I spent many hrs while driving planing a similar clock . tho this one was more of a sculpture standing about 10 ft high against a wall.
The driving force was a spring constantly being rewound at about 10 min intervals by a weight/ piston that is dropped into a cylinder then blown up between guides to rest on the winding arm again.
I am Glad to know I am not the only one who is loopy around here.

Brian,
You don't have to worry about that. Not on this forum anyway.

So I'm not alone...
I've also wondered if it would be possible to harness the power of a compressed car spring (either leaf or coil) to drive a clock. With that much stored energy, it should be possible to power a clock for many years. It would also look pretty cool hanging on the wall as a dynamic sculpture. Both of these are actually on my list of future projects.

So we have a start, the first part of the ball lift is made. This clock is being made "On the fly" so be prepared for changes of direction.
I think this will be a good project for alloy or plastic parts, cheap and easy to make and very visual in operation.

How it is all going to go together? I simply don't know.

Gear No2 this one will drive the hands,(motion work) 200 teeth on this one.
