Re: ?low temp issue
This is actually the second time this question has been raised with me inside 24 hours (the other being locally) and so I think I will try and put together a short ‘guide’.toggle quoted messageShow quoted text
Firstly, if you have a copy of “Synchronome, Masters of Electrical Timekeeping” by RHA Miles - this is fully covered in detail in Chapter 13. Can I recommend you get a copy of this ’standard reference book’ which is available from the AHS, here https://www.ahsoc.org/shop/books/synchronome/ There is full detail and illustrations there.
Secondly, I will try and follow up with a short summary of the key points, but to get all correct - there is a ‘method’ to follow, rather than just experimenting. I have to add that I have one slave dial that is definitely temperature sensitive and I have never quite managed to fully ’tame’ - the possible reason being that the coil may have lost some layers in the course of its history (it is over 100 years old).
I will try and put something together.
