David Walter Double Pendulum Clock Repair Part 1 - Calendar Problems

- I have just started working on another magnificent double pendulum clock, this time by David Walter. The clock in question is fitted with David Walters interpretation of the George Daniels perpetual calendar mechanism. The calendar has been causing problems and the client has asked me to have a look at what can be done. This video is part 1 of a series of ‘vlog’ style videos chronicling the repairs to this clock. In this episode you can see my raw brain bimblings as I get an idea of the problem at hand and arrive at a solution.

Fantastic. Thank you for taking the time to produce these videos. Facinating to watch your explaination of the mechanism and the issue. Thank you for sharing your fantastic level of knowledge and understanding.
You're very welcome!
Enjoyed this greatly. Loved hearing you describe your thoughts as you tried to fault find. Makes video more interesting/educational.
I’m very pleased to hear it. I’m still trying to find a video style that is both easy for me and enjoyable for you. I’m no video editor! I’m hoping the raw vlog style may be the way I go forward.
Good to hear your thoughts and talking us through this. Mind you this I s indeed a quality piece of work.. I wouldn't take it on but reminds me of good French engineering... Bravo.
Thank you, and thanks for watching.
Very well presented. Elegant looking mechanism. From watching your 'vlog' . I'm interpreting a design flaw. As presented. Waiting on round two.🕰🕰🕰
Thanks. It’s not so much a ‘flaw’ more of a minor oversight and the fault only arises under very specific circumstances.
@@TommyJobson Understood. "Murphy's Law" :)
Fascinating, and extremely well explained.
Agreed I am going to enjoy this series
If I'm understanding this correctly, the date mechanism is normally driven by the movement, and this results in no issues. If the time is moved forward by hand, and if the date hand is already on 31, it causes the date mechanism to become over banked and locked, making it unable to return without technical intervention.
The owner of the clock should have definitely had some idea what they were doing that caused the problem, IMO. From the sound of it they had it happen several times.
I was really hoping the adjustment you did to the date rack would have fixed the issue but it was not to be.
What an amazing clock.
Indeed it is!
Would it have also been a viable solution to add something in that very last tooth of the rack to prevent it from being engaged?
Essentially the same solution. Preventing that calendar wheel from engaging into another tooth but allowing just enough to disengage the catch paw?
Great job Tommy - just wondering would this 'forced hand lock' happen If the calendar wheel had less teeth (ie 42 instead of 44) ?
Not something I had considered, it would have an effect, but that would change the engraving on the dial, so not really an option.
Hermoso!!!!!
Isn't that mechanism still used in current clocks from DW? Perhaps they have an 'erratum sheet'....?
Stay tuned!
