I’ve just watched your video right through. It is very awkward trying to clean a movement without a proper cleaning machine. The mainspring repair is ok providing the screw does not rub against the spring. What types of oil did you use? The action of the balance is very poor, what about the time keeping. With such a powerful m/spring, when it is run down that balance will hardly rotate. I would check the whole escapement for old oil and make sure the jewels are spotless. It would have been a good idea to have assembled the train and tested before putting in the pallets. Good luck.  

 

Are you going to video the up-date when sorting out the balance? I do hope so.

I did take the balance out and cleaned it in an ultrasonic cleaner while contained in a smaller container. I did clean the jewels and the hairspring is now perfect. Got it swinging 270 deg now. It does run too slow: ind i have the regulator cranked over to fast. I could undercut the balance screws or even remove two and see what happens. For now, i am satisfied that it actually ticks, Phase 2 will be timing...when i get the energy.9abca5c1d08c1ea5405fc7eb5117b70c.jpg

I wouldn’t play around with the timing screws just yet. The best and safest thing is to take the hairspring in and re-pin. You will have to change the position of the hairspring on the balance to get it in beat but that is not difficult.

Ok, the problem was actually a loose cannon pinion. So what i did was use one of my wife’s hairs and carefully placed it inside the cannon pinion. Then i slide it back onto the pivot/arbor. This provided enough friction for the cannon pinion without having to tighten it the normal way. I was afraid of damaging the cannon pinion as i have no other hebdomas movements for parts. So my wifes dna is now part of the watch. Please don’t yell at me for using that technique. The swing is around 180deg.

I actually did not show the cleaning, only putting a few small parts in lighter fluid. I actually hand clean each part, peg out all the jewels, sink the pinions in soft wood and shine all the pivots. I also toothpick the movement plates to get any corner gunk out. Did not tape that as it would have taken another hour. PS: I do listen to all your advice over the years, Big Thanks.

I would have liked to have watched all that. Good luck.

The watch is now slow 5 min over the past 30 hours. Getting closer. Without a new “not set” mainspring, I don’t think i can get the amplitude any better.a0f71c197da5485aa203d1b626129191.jpg

      Movement holder made with 3D printer

      By Waggy · Posted

      So here is the new base (v 2.1), I made it so that the base will fit over and swallow the stump of the hand pusher tool (or at least my clone of the tool), I also reduced the OD of the bottom skirt a little as it looked/felt a little large, here are a few pictures and the fake .pdf file which you need to convert to .zip once downloaded.   The cut-out seen on the below image on the bottom of the base should swallow the OD (40 mm, +0.1 mm tolerance) of the stump and the height of the stump 9.5mm (measured to 9.1mm, but rounded to 9.5mm) - let me know if this works for your tool.   Note, I think you may need to print supports for the new internal shelf created?

      Balance spring fell out of regulator pin.

      By HectorLooi · Posted

      Hi Frank, you have dived headlong into the deep end. Hairspring work has to be the scariest thing a newbie has to tackle. Your hairspring appears to be bent and just putting it back into the regulator would not allow the balance to work properly. It might start oscillating but the performance would not be good. The proper thing to do is to unstud the hairspring, remove the hairspring from the balance, reinstall the hairspring on the stud carrier, reshape the endcurve and centre the collet to the balance jewel hole. This challenge would either make you or break you. Hope that you will be able to fix your watch. Welcome to the world of watchmaking.  Watch this video. It think it'll give you an idea of the task ahead. From your 1st photo, I think you have a etachron type stud. Let me see if I can find a video on how to remove it from the arm.

      Have read of the Tech Sheet attached on the balance section page 12. It may be bent but until you reposition it back in the regulator pins you'll never know. Cheers CJ 4R35B_4R36A.pdf

      Balance spring fell out of regulator pin.

      By Hawaiikook808 · Posted

      Aloha All, My Seiko 4R35B movement stopped working today. Upon closer inspection, it looks like the balance spring came out of the regulator pin. This is my first time working on a balance. Any advice on how to get this spring repositioned (back to normal)? I'm pretty sure that while adjusting the beat error on this movement, I must have turned the stud (I didn't even know they turned), and the spring eventually fell out.  Will the spring go back to even spacing when it's back in the pin, or does it look bent? Thanks, Frank

      Good job, that band matches the watch perfectly.
