      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?

      Cheers mates!!
      Had to get new winding stem to an Omega cal. 342 , beacuse not original crown.

      Hello all
      i wonder if anyone could offer some advice. I have an Omega seamaster 1345 quartz day date. Working well. However it seems the date is stuck (as shown in pictures) i know the push button at the 4 o clock position is meant to filter through the date? However when pushed in nothing seems to happen. As a result of this the watch works fine but only up untill 11pm it doesnt turn over to midnight and therefor change the day or date. Minute hand works perfectly but it seems i have to change the hour position every morning.
      when i turn the crown, hour hand moves fune and after the 12 o clock position changes the day, but date does not moth along with it.
      anyone know how i can resolve this safely without removing too many parts of the movement? 
      Many thanks

    • Make sure you have plenty of leg room. You could be sat there for hours so you do not want to be cramped up. 
    • good show,  you did good by not removing the balance till the main spring was let down.  "no pallets in this design!"   a watch "with pallets"  it is proper to remove the ballance before spring let down.   keep up the good work.   vin
    • Hi fellow Clockmakers, Would a bureau desk work as a clock/watchmaker desk? Not high enough (could be solved) or stable enough? I could fetch one of these from facebook around 30-40 pounds. I like the idea because it would be more or less child and dustproof as you can close and lock the whole thing. Best regards, lui
    • I have a monoprice voxel. It is limited in features compared to others but works out-of-the-box and was a good price. I wouldn't bother with a 3d printer for parts holders and the like. There are a few nice designs on thingiverse but really it isn't worth the bother. Injection molded supplies are going to be better quality and you can buy a bunch all at once instead of one waiting to print them out one at a time. Where it may come in handy is when you need something in a specific shape that you cannot buy. But keep in mind you will need to learn at least some basic CAD design. I use Moi3d which is excellent but there are cheaper alternatives. I've used my 3d printer to create different adapters and holders where I needed an exact shape. For example, I was bending a strip of brass and was able to create plastic bending clamps I compressed with some pliers. I was able to figure out the exact inside and outside curve I needed and print to match. The nice thing about the 3d printed parts is you can use glue to attach whatever you need to it without worrying about having to damage the print when removing it as you can always print a new one.
