Franklin Ferguson clock
« on: March 12, 2015, 02:15:04 AM »
I have built a Franklin clock, with the gearing 42- 72- 84 teeth. (See link),http://founders.archives.gov/documents/Franklin/01-08-02-0060
 It's a prototype, and it works fine, partly. Blessed Mr. John Harrison said: the problem is not the weight, but the friction. There, I have much to learn  :(!. I have a parallel project, the Ferguson one wheel clock.

In 1710 invented the astronomer James Ferguson the one wheel clock. (see link)https://www.youtube.com/watch?v=fbnQniG_odU
 If I could combine the Franklin clock with its four-hour spiral disk with Ferguson one wheel clock, it could be exciting.
But math is hard. There are two graham escapement and a gear wheel with 120 teeth to fit together.
Is there anyone who can such a formula? or where to find
Thanks in advance
Steen

I always find it very complicated to create or build clocks especially given that there are brands like Coolest Clock available, which are as cheap as it gets, but the quality is definitely first class which makes me like it so much and to talk about their features and facilities are seriously too good for the kind of price they are charging, so it has definitely become my favorite and I get all my wish completed there!
