• Upcoming updates
    Over the next couple of weeks we will be performing software updates on the forum. These will be completed in small steps as we upgrade individual software addons. You might occasionally see a maintenance message that will last a few minutes at most.

    If we anticipate an update will take more than a few minutes, we'll put up a notice with estimated time.

    Thank you!

    Junghans auxiliary winding mechanism

    One of the wheels on this movement has ratchet teeth which look typical. The other wheel's teeth more closely resemble those of a conventional wheel, and the click's tooth form doesn't seem to match. Unusual in my admittedly limited experience. Bill

    Nothing more annoying!

    I had precisely the same annoyance as you. After much digging in various forums, I ran across a brilliant solution that a few of our colleagues had devised. Instead of hammering, this tool is a press which is fitted over the movement, contacting opposite ends of the Gathering Pallet arbor...

    Ball Bearing "pads" on the Sherline steady rest.

    Bill, I used 1/4" square W1 steel bar, as I had some on hand. I used my lathe to turn the ends, make the bearing slot and drill the bearing axle hole. I held the workpiece in the carriage mounted tool holder. Only thing I used the mill for was radiusing the ends (although this could also be...

    Waltham Factory Sixis Tool

    I would love a copy but the link goes to an area in google that is access denied. All you need is a gmail account and password to log on. I was able to download the file without a problem. Bill

    ibm/itr pendulum.... mercury?

    Bruce, I never attempted to dismantle my pendulum as it appeared to be in pristine condition. So I cannot comment on disassembly. When I carefully tipped the pendulum sideways the resultant displacement of the mercury was felt distinctly. Since no leaks were evident, no need to fix something...

    Is there a minutes advancement tool?

    M, When I bought my letdown tool set, the smallest ones weren't included. I ordered the missing sizes from Timesavers, IIRC. Bill

    Is there a minutes advancement tool?

    M, Smallest letdown bit I am aware of is size "00" which measures approximately 2.25 mm across the flats. No doubt smaller clock minute hand arbors exist, but to date I haven't encountered one. Bill

    Is there a minutes advancement tool?

    Thurmond, I use the appropriate size bit from my mainspring letdown tool. Just the bit without the handle works well. Bill

    Is anyone using Stereo Eyeloupes for Clock Repair?

    I use the Zeiss binocular loupes in the photo. These have been in production for a long time, mine are current manufacture with titanium frames which makes them noticeably lighter compared with earlier examples. Working distance is approximately 10". The optical quality and field of view is...
