3D printed Hairspring Holder

Over the last 2 weeks at my watch and clock repair class we have been learning how to manipulate hairsprings.

We were shown that if you sit the hairspring on a sheet of glass and have it raised up by a 1 or 2cm over white paper the shadows of the hairsping are out of your way making it easier to see what you are doing.

After the first night of playing with hairsprings I went home and designed myself a holder based around some 50mm spare torch glass I had lying around.

I also added cross hairs to make it easier to work out where to hold the spring when adjusting it.

This is my end result.

Should anyone have a 3D printer and want to make one themselves I've uploaded it to Thingaverse. The glass I used was 50mm diameter and 1.5mm thick, but it should also work with 2mm thick glass. The parts are made to friction fitted so you don't need to glue it so it can be taken apart if needed to clean the glass.

Bottom photo shows a clock hairspring I had fixed and I'm in the process of attempting to make it a breguet overcoil, for no other reason that practice

Why use the simple way when you can have it complicated?:)

For the same purpose I use the top of a 10ct aluminium box (there are plastic ones, too) with glass window. In the side wall I cut a light window.

Only simple when you have it available. :-)

Besides it gave me an excuse to use my 3D printer which I hadn't used for a while and I've been wanting to make something for use in my watch repair course for some time, but until this I couldn't think of anything to print that I thought would be of suitable quality

      Help with Hermle ships clock

      By watchweasol · Posted

      Hi Mike I did a ships clock a long while ago, not a Hermle though and without getting the beast in my hands to refresh my memory I can’t recall the timing.  This doesn’t help I know but will start the grey matter turning.

      Of course it will continue Richard.

      Help with Hermle ships clock

      By Rixy · Posted

      I have stripped and cleaned a Hermle ships clock. It was just oily, no major faults, and I reassembled it, following my photos in reverse order. The time train is fine but the strike train will not play the ships bell strike for half-past. Ships bells play a four hour sequence for the 'watches' and play double 'ding' for the hour and the double dings plus one for the half past (eg half past the second hour is 'ding-ding' 'ding-ding' 'ding'). Sounds complicated but it isn't really. The strike wheel consists of pairs of bumps (for the ding-ding) and no single bumps. There must me some mechanism on the half-past that lifts the strike lever over one of the bumps so only one ding is played. When I get to a half past, it still plays double ding. I have a feeling it is to do with the lever in front of the rack (there is a sprung attachment  on it) and the position of the wheel (to the right) with the two pins that lets that lever fall, but no matter where I place that wheel I cannot get a single ding at half past! Please can someone help with advice on positioning so I can fix this? BTW Happy Easter 🐣

      Who's doing what in the world of watches today.

      No it's not 52. I had looked at the Pocket Watch lift angles thread, which lists Elgin 6s as something really high like 62° but visually that is not at all what this watch is doing. I think 42° is more correct and that's where my machine is setup. The watch has a million problems but I have made solid progress. Impulse jewel replaced. Hairspring didn't match the balance (which also doesn't match the serial) but I got it down into range this weekend with 8 or 10 huge timing washers. Replaced the mainspring, balance and train are nice and free. At this point it is running consistently and in beat at about 160°, the third wheel has a bend that sends the timegrapher on a little roller coaster every 8 minutes or so. Remaining amplitude problems may be down to the escapement. The banking pins were way out and it didn't run at all before I started. It has one of the old brass escape wheels rather than steel, and I assume the faces its teeth are probably worn or scored in a way I can't yet fix (or see without a microscope). I know this watch is not going to run above 250° but I am going to keep trying to get above 200. But the best part about this watch? Some unscrupulous person stamped "21 JEWELS" on the train bridge sometime in the past, right on top of the Damascening. It's a 15 jewel movement.

      I think it would rather be the blast of high current drain that would do the damage. But if used occasionally to maybe fix a mainspring or do dial feet it might be worth trying especially if the mainspring or a replacement couldn’t be found.    Tom
