  1. I'm working on a Waltham aircraft clock that has two broken mainsprings. The mainsprings have holes at both ends for attaching to the arbor and barrel but the new ones I received have a bridle at the barrel end instead of a hole. Is it possible to use the bridle end even though the barrel has the tab for a hole end?
  2. Thanks, jdrichard. That led me to the click. The first photo shows the click which disappears in the second photo as the watch is wound.
  3. I'm working on a Waltham 8 Days aircraft clock from WWII. It has dual mainsprings which are wound up. I need to unwind them before going any further but am unable to locate the click. It appears that any further disassembly will affect the drive train. Am I overlooking something obvious?
  4. There are four mainspring winders in the lot but nothing that looks like it would go them to hold a mainspring.
  5. Now that you've identified some of the items, I see things on them that I initially did not catch. The slotting file has very fine teeth on the edges. The center holes on the screw plate are threaded.
  6. Thanks for the info. It led me to this YouTube video showing how the base is used with the lifter. A lifter was included with the tools I received.
  7. A friend gave me some tools that he inherited from a watchmaker. I can't figure out what some of them are and would appreciate your help in identifying them.
  8. Not sure what was on the pallet jewel but it looked fine once I removed the pallet fork and put it under the microscope. The next step will be to adjust the pallet jewels which will take some time. I've not worked with shellac before so I'm reading up on it.
  9. As requested, here are two videos of the pallet jewels interacting with the escape wheel as the balance wheel is slowly being rotated. I should note here that since my last posting, I experimented with the banking pins which appeared to be adjusted further out than needed. I brought them in a bit and the amplitude jumped from 166 to 206 degrees. ball_entry_2_Trim.mp4 ball_exit_2_Trim.mp4
  10. Nickelsilver - Thank you for the explanation on how to check the escapement. I found it difficult, however, to perform some of the checks, particularly the fork horns and safety which I could not observe on a fully assembled movement. Below are two photos of the pallet fork jewels as they engage the escape wheel. There is power to the movement but the balance wheel is removed. The first photo shows the entry jewel and the second the exit jewel. Not sure if these photos indicate much but I will try to get some measurements and better photos within the next several days.
  11. I checked that the pallet fork jewels were properly engaging the escapement wheel and that the pallet fork snaps from side to side when nudged. Information that I found on the internet for setting up the escapement seems to focus on the banking pins. Is this what you're referring to?
  12. It's good to hear that the sideshake isn't as bad as I thought. I haven't checked the escapement yet and not quite sure how do to it. What should I be looking for?
  13. Thanks to everyone for your inputs. Upon further examination I found significant endshake, not so much in the vertical direction but rather from side to side. In the attached video, I'm gently touching the balance wheel and you can see the play with the pivot. To me, this endshake looks pretty serious and that I'll have to replace both jewels and balance staff. Any thoughts on this? ball_balance_jewel_Trim.mp4 ball_balance_jewel_Trim.mp4 ?
  14. Prior to servicing, the Hamilton pocket watch I received had an amplitude of only 130 degrees. During servicing, the mainspring was found to be weak and was replaced. After a routine cleaning and lubing, the amplitude had only risen to 166 degrees. Looking at possible causes, I could detect no binding in the gear train, pallet fork or balance wheel and the timegrapher line looks clean. There is, however, a significant difference in position: DIAL UP +7 sec 166 degrees amplitude 0.2 ms beat error CROWN UP -34 sec 126 degrees amplitude 0.1 ms beat error I'm running out of ideas at this point. Could a weak hairspring or worn pivots cause low amplitude or am I overlooking something?
  15. I shimmed the balance cock with a strip of mylar .05mm thick but there was too much end shake. I then tried a strip of aluminum foil .02mm thick which was just right.
