  1. Welcome to the forum Ted. This might help you; Tech Guides/Omega tech Guides/1310.pdf
  2. I love it..............I want one.........just to look at!
  3. I use option 1 all the time.
  4. It looks like you will need a wide bifurcated screwdriver to tackle this one. That is a screwdriver with a notch slightly wider than the threaded screw in the centre of the nut. Being a special, it's one you will have to make yourself to ensure a good fit.
  5. The only time I have used one in relation to watchmaking, was checking a couple of components for running true when using my watchmakers lathe. It is unlikely that it would be used for anything else, especially shimming a balance cock. This is something I would do on a trial and error basis, i.e. add shims until you get the the clearance you require by feel. Anyway, you have a jacket tool and would be able to shorten the balance staff to get the correct clearance; this would be the correct way to go.
  6. It is indeed a dial test indicator. This is usually clamped to the vertical rod on a magnetic base, or in the tool post on a lathe for setting up work to be machined. It can also me used to test for roundness or linear inaccuracies depending how you configure it in relation to the work being examined. Another common use is for setting a vice on a milling to ensure it is perfectly in line with the milling table. There will be many more uses for this precision tool, mostly limited by your requirements and imagination. The one you have in the picture will measure + / - 15 thousands of an inch.
  7. Micky, I hope you haven't been wearing it since the 20th of March???
  8. Another excellent post John, thank you!
  9. Rather than throw them out Stephen, use them and cut the thick rubber ring with a pair of scissors when fitted. This greatly reduces the pressure and will at least allow you to use them. This is exactly what Inam doing just now to work my way though some tight ones.
  10. I hope you havn't caused more damage by bending the hair spring. Have a read of this, it may help.
  11. Pictures would help folk understand exactly what your problem is and advise on what you require.
  12. Definately not a railroad watch the standard looking quality and lack of regulator fine adjustment is just not there for that. I think it was made to commemorate Lord Roberts military campaign in the second Boer War of 1900. Here's some positive information:-
  13. Marc. Maybe the "screw" hole stops just short of breaking through into the stud hole to allow a small punch to be used to dimple the stud hole slightly. This would allow the stud to be gripped in the hole and also allow further tightening of the stud in the hole later on if required. Just a thought!
