Hi everyone, hope you are all well.I am having problem with this French clock as soon as i put the pallets into the pivot where this adjusting screw is, sorry don't know the name of this part the train will not turn, i found this out after starting with the barrel and working up the train to the pallets if someone has turned this screw and i hasten to add it wasn't  me,would this be the cause of the problem and how do i go about rectifying this.

Thank you.

Hi Willow  as you look at the screw there is a slot in the back plate align the screw slot with this and then try again. normally these screws are factory set and do not need adjusting as the depth is set up. If some one has turned it it begs the question ,why,  the "Brocot" escapement is usually very good unless its been worked on by some one.  You have basically to reset the depth on the lockings on the pallet, check the pallet surfaces are not worn or chipped and highly polished (mirror finish). Fit the pallet anchor assembly and wit a couple of turns on the spring check the action and adjust untill it locks and unlocks then try the clock for running. Might take a bit of time going bit by bit.  all the best

Hi willow, just be careful when moving the adjuster they are usually very tight primarily because they are factory,  set use a good well fitting screwdriver to avoid slippage. As you see the screw adjuster is circular and the bearing is on the side any adjustment will go up/down in an arc. If as we suspect its been moved the lateral and vertical positions have been compromised. put a small dot in the position it is now and when refitted check the action and adjust accordingly.   all the best.

Hi willow  have a look at this bit of reading might be of some help.

Thanks for that watchweasol great bit of information pallets unlocking now, clock running just needs a bit of adjusting as it stops after  5 mins but making progress .

If it is stopping because of the escapement check all the pivot holes for the escapement, pivots and burr on the escape wheel and the angle  of escapement the pallets also need to be smooth with no marks or signs of wear. I can't tell by the photos but many clocks with this type of escapement the crutch is friction tight, so it has to be tight enough for it to work, too lose and it will stop, to tight and it won't set its self in beat.

Hi willow   with it being a deadbeat(Graham) escapement (no recoil) it has to be right, The diagnostic path as laid down by Old Hippy has to be followed and all points checked. A recoil escapement gets a bit of help from the recoil and can overcome little problems like slightly out of beat or locking. Its a question of patience and dilligence.   all rhe best

Hi oldhippy, the crutch on this clock screws on and off, away at the moment will check when i get back thanks.

      My first Gruens. Precision 510 and N510R movements.

      By rjenkinsgb · Posted

      Snap! I recently finished my Gruen 510 movement - though the case for mine is in a rather sad state; I'm going to try re-plating it (in nickel, it's not a gold one).   Re. the screws, I got a few of the one gram mixed batches from ebay. I've only needed a couple of screws for things so far, both rare, minuscule types - but both in the mix, after enough time sorting through them! The ones such as normal bridge screws are quite common in those lots.

      Any tips to correct a sloppy error?

      By rjenkinsgb · Posted

      Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      Movement holder made with 3D printer

      By GuyMontag · Posted

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      By Neverenoughwatches · Posted

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.
