Balance becomes sticky when interacting with pallet fork

To be clear, I meant the hole jewels looked fine. Clealry a missing cap jewel is not fine!

Your thread went every which way but loose 🙂.  So if one of the balance cap jewels is missing this will impact on how the balance oscillates. The endshake will be excessive besides the fact that the staff cone could be riding in the balance jewel when the pivot should be on the cap when that way up. The escape wheel and balance need to  be set to the correct height for each other so they have proper interaction and also have the same amount of endshake so their interaction remains the same throughout positional changes. If end cap is missing on one side of the balance then there is going to be some misalignment when that pivot is downside. That could well be your sticky problem .

      I used to have a lecturer during my Engineering classes who was always beating a drum about quoting units, I remember one day he was so exasperated with our class he said "quote your units!!!!...I don't care what units JUST QUOTE THEM!!!" My next assignment I calculated the velocity and quoted the units, something along the lines of: "Thus the velocity of the body will be 0.00345 furlongs per fortnight" He graded my work as an F, then crossed it out and gave me an A+, turns out he had a sense of humor after all.

      Just to add to what @Neverenoughwatches says, the impulse jewel on the balance wheel is also held in by shellac, so avoid exposing the assembly to IPA as well - as stated the one-dip and generic tetrachloroethylene equivalent is safe with shellac so you can use this for your pallet fork and balance assembly. I agree, but worth noting that IPA readily soaks up water, even from the atmosphere: "IPA exposed to the air will absorb moisture rapidly until it reaches an equilibrium value of 65% IPA to 35% water." So you need to refresh it regularly.

      The width is otherwise known as mainspring height and strength as thickness for us more modern guys.

      I've remembered something I had forgotten.  I've come across Dennison before but forgot all about it as I'm never going to use the units.  Maybe we should start a  thread on obscure units of measurement.

      Learned a new thing today! 🤓 Looked this up and found this informative document: Watkins-MainspringGauges.pdf
