      Hello. 
      I am about to work on a Omega ladies automatic watch.
      I found out that the axis of the rotor is out of place and shakes up and down.
      What could be done in this situation?
      Thanks!

      I have an old Waltham pocket watch movement which is missing the impulse pin (roller jewel).  I have a limited number of actual jewels and since this is just a practice movement I thought I'd try to make one out of brass.  I've seen this several times in old pieces--usually a very sloppy job.  So I got some brass stock of the same diameter as the "D" in the roller table, filed it and burnished it to a high gloss.  Then I took a small, very fine diamond file and filed it half flat to form the "D"  I then polished the face using progressively finer sandpaper on a steel block.  This works fine--so far!  Problem is separation of the piece from the stock.  Again I used a small cutting file to do this but it doesn't leave the end very pretty.  So what I've done so far is to fit the good end into the roller table.  I then plan to shellac it in place and see if I can very carefully adjust the length and clean up the end.  Has anyone done this before?  Any suggestions as to how best to do it?

    • I love quality but IMHO cost must be reasonable for the intended (hobbyst) use. So I'm putting the $32 link anyway  https://www.aliexpress.com/item/32634442471.html
    • Nicely done. I've only made 1 balance staff so far. I've got a German aircraft clock that has a broken endcap jewel that also had both ends of the pivots worn flat. I've rounded them again and once I've received the new reamers for my jeweling tool and fitted the new endstone I will find out if I will be making my second balance staff as it may now have too much endshake.
    • I think this could be done out of brass with a three/four jaw chuck. The threading would be very tricky...unless you do snap on. Sent from my iPhone using Tapatalk Pro
    • Thanks. Not sure how I would advertise? I actually love making balance staffs. The new DSZ-70 stereo microscope is great for examining my work and seeing any defects in the parts. Still cutting the part with x20 loupe however. Here is my messy desk Sent from my iPhone using Tapatalk Pro
