Had to make a balance staff for an Elgin 16S Pocket watch. Used the old on as a sample and cut 90% of the staff without flipping it around. The pivots were 0.12mm and I needed to use the Jacot tool to remove material from the pivots for the final fit. As well, I shaved too much material off the hairspring side and needed to reduce the size of the collet with my staking set. Also needed to adjust the hairspring as it moved when I compressed the hairspring.

Mate that is excellent work, have you a cross slide on your lathe or did you do all that with hand gravers?
 

Did it all with 2mm flat and rounded gravers. Take the big material down with 5mm gravers. I do have crossslides but this work needs to be done by hand to take precisely the right amount of material as the balance is friction fit.

Fascinating and inspiring as usual. 
I trying not to get inspired too much.

Inspiration equals cost:) Only curious people do this work.

      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.

      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 🐣
