In 1596 Rudolfo Margraf clock maker to Roudolfo 3rd ( Hapsburg ) made a rolling ball clock with a fixed inclined plane and a lifting system to return the ball to the top.
I intend to use this basic idea to make a modern version, using plastic and alloy for the main parts of its construction.

This clock will be made totaly "On the fly" so things may change as we go along??
The first part to be made is part of the ball lifting system.

Hi all.
I have not finalized how I am going to lay out the frame plates for this clock, so I am going to make the gears first ,before commiting myself, the inclined plane takes a lot of room .

As the other folks have said.. Thanks for the creativity and inginuity, I learn so much from your threads.:))
 
Further work on the ball lift wheel, 215 teeth added to the outside diameter to drive a pair of fly's ( two for visual ballance) this is to controll the lift rate, and the two small drive gears made.
I intend this to be a very active clock, with things moving all the time.

What type of plastic are you using ? Plexiglas, polycarbonate, or other. Do you think there would be a notable difference in them. Apparently there is not a consideration in wear even though a lot of movement in it. I ask because I'm about one third through a wood and Lexan gear clock. Gears cut but haven't had a chance to fit them yet. To many interruptions.
Anyway I sure oughta learn something here. Thanx Brian.
