  1. There are four mainspring winders in the lot but nothing that looks like it would go them to hold a mainspring.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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
  7. 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.
  8. 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?
  9. 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?
  10. 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 ?
  11. 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?
  12. 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.
  13. I removed the balance jewels thinking that whoever serviced the watch before may have inadvertently swapped the upper and lower jewels but the lower set had a slightly larger diameter so they could not be swapped. It did appear that one of the lower jewels was installed backwards so I reversed it. This made a big difference in that the timegrapher line cleaned up and variations in both amplitude and rate were reduced when placing the watch in different positions. Still, I had to back off the balance cock screw about an eighth of a turn otherwise it slowed down the balance wheel. I don't know if the balance staff is original or not but don't want to take the chance of shortening and possibly damaging the pivots. At this point, I'm tempted to go with the shim as the watch performs well once the balance cock is raised slightly. In my original post I misidentified the movement as a Hamilton 992B when in fact it's a 999P.
  14. Yankeedog - Good point about the service record. I suspect that the watch may have been serviced before as I had to replace the mainspring and the correct Hamilton one was several centimeters shorter than the one I replaced. It could be that the balance jewels got swapped in the previous repair. Well, I guess there's only one way to find out.
  15. When you say "see if the balance is round and flat", what part are you referring to?
