A David Walter Double Pendulum Clock – Part 10, A Milestone is Reached !
A David Walter Double Pendulum Clock – Part 10, A Milestone is Reached - The Equation Movement Finished Every week we are seeing more of David's work on his new double pendulum clock. A milestone has been reached, the first movement, the equation movement...
One of the wheels is wonky...?
Is it my sherry or my eyes deceiving me? But one of those wheels is wonky and looks like an egg! The one on the left is not perfectly round ;) Just kidding...I'm messing with my own head. It must be the sweet sherry. This must be one of the most detailed ...
I highly recomend Dry Sherry........
The all will appear less wonky. That is the equation cam, sometimes called the kidney cam due to its shape. David
Is that a ruby tipped follower...
...on the equation kidney? I think it is. I have thought of trying that myself eventually, when I get a chance to make equation works someday. I see yet another "1st" has already been done by someone else. Not disappointed- it must have been a good idea i...
Yes it is......
a ruby rod, the end is slightly bull nosed as it must follow the cam at varying radii. On earlier clocks I had a long lever indexing the year wheel from the left hand side, this worked well but the long lever had more mass, the new version is much lighter...
How it works...
Hi Don, How it works is easy ! the thingy in the middle shoves the whatsit on the right which kicks the gizmo over then every now and again that lifts the whojaflippy that turns the gadget who waves an arm at the bull and the that shows the equation ! Dav...
The real story
The real story - how it works Hi Don, Explanation; I have attached a pic of the movt. upright as this is how it appears on the finished clock and it is somehow easier for me to explain if its the right way up. The wheel immediately above the cam wheel at ...
That makes sense
It's a bit difficult to make out all the details exactly from the picture, as zooming in on pins and such just gets blurry, but the explanation, coupled with what I can make out, and my knowledge of this type of equation mechanism from Daniel's books, esp...
David and Don, thank you from all of us
David, I know the making of watches and clocks is a huge task, and interrupting that work for photos and commentary adds to the effort. I hope it also provides a welcome distraction, or at least adds a sense of satisfaction that you (together, as Don too ...
