Yeah, thanks, Dell. I know what you mean. I had a slight complication with this one, as I managed to break a carbide drill while drilling the hole. I was left with a much shorter hole than I wanted and couldn't remove the drill fragments. Silver solder seemed the best option, giving me a much stronger pivot. Also, as an escapement arbour, it has very limited movement, so I felt the wear issue wouldn't be a concern.

*****@*****.tld I have a swimmer 30 jewel, with the day at the 9pm - which i cannot find any record of anywhere. The issue i have is that i cannot find a way to adjust the day - any ideas?

Nice work but for future reference I just twist press fit a new pivot in the heat from silver soldering would have annealed the arbor & of course the blue steel wouldn’t be hard either just my suggestion.

I managed to sort this in the end. A gentle couple of turns with a broach straightened things out. That allowed me to move on to the next problem, a broken pivot on the escapement arbour. I've never needed to replace a pivot before, and this is the kind of clock you don't just buy spares for.... The new pivot here is shown before polishing. I cleaned up the end of the arbour, drilled a new pivot hole, and silver-soldered a piece of blue-steel steel into place. Cleaned up the solder and pivot on the lathe, polished it up and fitted it to the clock. Quite pleased with the result, which looks more substantial than the original. The clock has been running perfectly on test for the past couple of days. Just doing the final regulation after casing it up, and it's back to the owner.

do you have a picture of the staff and movement?
