I've just started learning Autodesk Fusion 360, which is free to businesses under $100,000/year and hobbyists. It's a full 3D program that will do CAM - it generates the M-Codes needed  for CNC machines.
The learning curve is very steep, but then the program is fully capable and it's fully cloud based.
General Discussion / Can a clock keep itself wound?
« Last post by jamesmatheson on September 29, 2017, 05:10:55 AM »
Thank you for letting me join.
I am trying to have made a gear system to prove a clock can keep itself wound.

There are no more clock maker in Canada

So I am trying my very best to use clocks to help with sceince.

I am trying to show that if a 30 pound spring
Keeps a 10 pound spring rewound
That if geared correctly
The 10 pound spring can keep the 30 pound spring rewound
And it will run continuously

Takes some gear cutting and assembly . Hopefully someone will be able to do.

Here is a picture

It says 5 pounds but it's meant to be 10 pounds or anything the 30 pound spring can keep wound to operate continuously.

A chime releases 60 grams longer than a time movement ( on average with no regulator a chime works 20 minutes and a time movement works 5 minutes)

If 60 grams is the rewinding force 
then a chime set to release 60 grams can rewind a movement of any strength as long as it rewinds at less than 60 grams.

So if a 30 pound spring  with a time movement with bigger gears is set to rewind at 60 grams in 5 minutes.

Then a 10 pound spring with a chime movement that releases 60 grams for 20  minutes can rewind the 30 pound spring and the 10 pound spring will have 15 minutes of strength left over.

So a 30 pounds spring that rewinds in 5 minutes at 60 grams
Can be rewound by a 10 pound spring set to release 60 grams for 20 minutes

This has stumped everyone in all of Canada and I am hoping you will break this mystery for the 35 million people in Canada who can't make a clock

You will be helping a lot more than only the clock industry

Please help us with this

Your time is truly appreciated

I recently completed a wooden version of the "Big Wheel Skeleton Cock" by John Wilding.  I used ball bearings for the big wheel and delrin for the rest.  I found that 8 leaves was just too small for the first pinion so I doubled it to 16.  It was in the power train so had no affect on the time train.  I used a pair of constant force springs for power and the clock surprised me by running 12 days on a full wind.  I don't know how long it will last but is has kept good time so far.  I used a .04 English module so I didn't have to raise the ceiling.
