Stripped a chiming wall clock movement today. Customer said it had just stopped. It was not that dirty cleaned the wheels plates etc and then found this. It's the first wheel that drives the watch movement side I presume this is not repairable. It also needs re-bushing but with this there is now no point.

That needs a completely new pinion cut, then the wheel will need to be remounted. If it is a relatively new clock and you know the make you might be able to get a replacement. Do you have someone that undertakes wheel and pinon cutting?

Thanks that is what I thought. I might have been very lucky in that I have found the exact movement (Haller 8 day) on ebay & I have put in a bid for it. As for cutting pinions there is a guy that advertises in the BHI mag. I also found some standard pinions on the "Timesavers" web site. Hoping I win the clock movement.

PS the clock is a vintage wall clock and has had re-bushing done but very poorly and it really needs re-bushing again. It's up to the customer how much they are willing to pay.

PPS for future reference I presume the wheels are friction fitted. 

What fun !!!!

      Smiths rim wind and set

      By transporter · Posted

      Ok, as per pictures I have a smiths rim set and wind on the bench, swimming in oil but all sorted. The fault I have is the mainspring bridle has lost its tab/notch/hook, like a hebdomas pocket watch the mainspring is fitted to a bridal in the barrel which slides around on full wind onto 4 notches in the barrel wall, thus stopping damage to the mainspring by over enthusiastic winding. So my questiion is this, what is the best way to create another hook in the bridal, my thoughts are along the same lines as making a new hole in the mainspring end, annealing etc, but what and how to make the hook?? I have a pair of barrel hook pliers that work great in soft brass but won’t even scratch the bridal, what I don’t want to do is whack a hole into it and not have a hook. the pictures are of the bridal ( broken) and a hebdomas ( complete ) incase you are wondering what I’m on about. And a few of the serivce. Thanks for any advise.

      Replacing, upgrading Ronda 715 Harley?

      Decided to give the case and bracelet a good cleaning and my first shot at polishing/brushing. Went with the Cape Cod polishing cloth and gray scotch brite method.  Before First; Then After; Then comparing to some original links from when the watch was new to now.

      It's either bent or hung up on something or both. The hexane won't hurt it, and hanging from a balance tack indefinitely won't hurt it.   If the spring is glued to the stud there's a chance that the glue was softened and the outer coil stuck to the stud. Haven't seen that happen, but I suppose it could. Don't know if hexane affects the glue used either.

      Hello all. some help required here from the community please. I serviced this movement, which was running reasonably well, but the balance spring which was running healthily before I started, after cleaning in hexane for 30 secs, is all bunched up at the stud. I did store the balalance on a tack thereafter for a day.   could the spring be strained under gravity? I demagnetised of course, and the balance is squeaky clean. some help would be much appreciated. Thanks, Tony G
