Have you tried this put a little power on it and move the crutch with your hand and take note when and where it fails to escape and mark it with a pen or something that doesn't leave a permanent mark, you can then see if it is just one or many. I trust pivots are nice and smooth and no bushing is needed. Do the wheels have end shake and are nice and free with no power on. Pallet faces nice and smooth. As the crutch is a self-put in beat is it loose because that can cause the clock to stop, it is better for it to be tight then loose.

I have encountered the fault with the escape teeth being bent and worn. I found the best way to identify the badly bent teeth was to make an impression with one half of the escape wheel teeth in some Rodico and using the impression to find the teeth that need adjusting. 
PS the very last thing I would adjust is the pallets.

While i am waiting for some filler for the porcelain dial face of the french clock, i decided to send for a mainspring for a Rotherham clock, and noticed a number EMO 60 on the mainspring can you order one with that or do the usual way thanks

Me neither just order by size and strength. Whilst on strength I read somewhere if the barrel inside diameter is say 30mm then the spring strength required is 0.30 etc. I have checked this theory by measuring springs in clocks I have repaired and it seems correct certainly within +/- .5.

      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.

      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
