    No argument here. It is Mark's forum and only he can make a decision regarding this matter.

    Omega 861 Chronograph

    It's a valuable and complex piece, please take the advice above and instruct your customer to take it to a specialist. You could be in a world of expensive hurt if you go ahead and possibly damage it.

    Please do Richard, my very best wishes from Scotland.
  7. Geo Makes sense, sonic shock wave transfer energy in fluid fields, match the natural frequency of a mass body to break it by the energy imparted to the body.

    If you got no result blasting away vintage dried oil, you just have not matched it's bodies natural frequency.

    Geo got results with his ultrasonic cleaning machine, shows he produced the required natural frequency in his machine.

    The question remains, what machine provides the range of frequencies required to blast away the dried oil in a jewel? I think Ultrasonic machines have been designed to produce many frequencies simultaneously which add up sinusoidaly ( fourer functions), yet we hear some folks saying ultrasonic are no good for cleaning jewels and others say they are good.

    Uncle Larry is retiring.

    That's sad to hear. I have dealt with Larry on numerous occasions and found him to be an absolute gent. It doesn't sound too good, but I would like to publicly thank him for his excellent service over the years and wish him all the very best.

    Tool porn!

    I managed to pick up pretty much all that you have there JD, only not as a dedicated set. I really do like boxed sets of tools like that.

    What happened to Bobm12?

    Joe, I tried contacting him a couple of month ago but had no joy. If I remember correctly he did have health issues, so let's hope he's OK.
  15. I would suggest that you have it serviced. Do not put oil down the pendant tube, it will cause more problems than it solves as there is no saying where the oil will end up.
