Please help a beginner! I’m having  Great difficulty in aligning the escape wheel  on this FHF ST96.

i checked the pivots,no apparent damage …bt the upper pivot won’t enter its Jewell , indeed when axially aligned the pinion seems to be nowhere near the 4th wheel teeth. So I spent much time repeatedly replacing the train wheel bridge, but no luck yet.the lower pinion is correctly aligned.

grateful for suggestions, please!

If you look down at the escape wheel's pinion in relation to the center of its wheel.  They do not look concentric because the pivot is tipped away from its intended location.  Can't see if the other pivot is in the jewel but I would hope it is.  Nudge it back into position while fitting the bridge.

Good luck.

Hi tony. Can we have a nice close up macro shot of the top pivot. This one is prone to getting bent when replacing the train bridge. It can be the last one to place and its the smallest of the trainwheel pivots. One trick is to place a screw in the bridge very lighty and work  the train wheels in one by one without trapping them.

Well, thank you one and all for the welcome advice.patience and perseverance won the day!

what I learned:

check all components under magnification.Take a break!

also I didn’t Take into consideration the side shake and end shake engineered into the components when assembling.

thanks once again all.

      Gilding after silver soldering

      By AlanB · Posted

      When faced with say a pocket watch bridge which is cracked, silver soldering to repair is often the only option (hopefully someone wasn't there before hand with soft solder). I can generally do this succesfully and tidily with a small torch and miniscule pieces of silver solder, but on parts which were mercury amalgam gilded the heat can have have a deleterious effect on the finish.   I keep wondering if there's a good way to refinish these - and despite having the needful items would rather avoid using the mercury process.   In the past for electronic work I've gold plated PCBs but this involved gold potassium cyanide solution, which also doesn't realy belong at home. I've read that there are now safer alternatives but couldn't find more detail (and importantly how similar are the results to amalgam gilding, since I wouldn't want to refinish the whole watch). Pointers would be very welcome (and yes, I know solutions containing gold won't be cheap!) Alan

      Ok so with the great answers for my previous question may I ask what these two attachments are used for. The one with the red knob is I assume used for hand setting the seconds hand? Jon

      Roamer Searock Crystal problem

      By Zedster · Posted

      According to Cousins site I need to look at document G22 as I think I need an ATGB at 304 but I cant find this size in G22 doc. The last thing I want to do is order the wrong one😳  Unless I cant see the wood for the trees 😆 I could be looking at the wrong style, I assume its classed as Round plastic Armed  https://www.cousinsuk.com/product/wide-ring-gold-atgb

      Dial feet removal

      By JonC · Posted

      When building a new Watch I have tended to use a file to remove the remnants of dial feet that are not needed as many dials come with four feet to accomodate different movements, but this can be a bit messy so now I use this with a great deal more precision as you can use an appropriate bit for the job and keep it very localised.
