It’s got 8 gongs and plays 3 tunes and that’s where I come unstuck its ok taking things apart it’s butting them back together again. I won’t to know how to make sure that the drum goes back in the Wright way. I have but same photos on so you can see the drum and the style of clock Phillip

What you have is 8 day chime with under slung hammers. I expect it plays Westminster. Whittington and St Michaels. You say drum, if you are referring to the drum with pins on that lift the hammers don’t worry that is easy to sort out. What you need to do is take many photos, pay particular notice of the chime side with the wheels with pins in them, the same goes for the strike side. I can help you in every way in repairing this movement from taking it apart to putting it together. You must let the three springs down first. Do you know how to go about this? You will need a clock mainspring winder to do this properly. Do you have one?

Hi thanks for the reply I have only done this ones before and let the springs down with the key and the help of my wife. I don't have a mainspring winder , What would be the right way to let the springs down . And you refer to the wheels with pins in them the drum as I call it is one piece with a pinion or small cogwheel on the end that moves back and fore for the  melodies. And I want to make sure it will play from the start not halfway when I but it back in the clock

Don't just use the key to let down the spring, great way to break your fingers.

I have an old drill chuck mounted onto a wooden rod about 40mm in diameter and 20cm long.

You attach the drill chuck to the winding post (Yes the drill chuck only has 3 jaws and the winding post 4 sides, but it holds well enough).

You hold the wooden rod with one hand and with the movement held securely by someone else or in a vice with soft jaws release the click and let the wooden rod turn slowly in your hand.

You can buy let down tools similar to what I made with the drill chuck that actually have all teh different size winding keys that fit in them.

Hi there I have taken out the drum and placed a photo on here. Have a look and see if you know the make. of the clock. Now to let down the springs but it wont be until its a lot warmer and I can go down to my workshop and make a spring winder about the middle of April my old bones don't like the cold

Make sure the movement is level.

With the pallet plate back on using the two screws. I hope you have put it back at the same depth as you took it apart. Give the going side a few turns so its got power. Place the pendulum back on and with you finger give it a swing and if it sounds in beat it should have an even tick tock. If not, it looks like the crutch is friction tight to the pallets, you move the crutch a little until you hear an even tick tock, depending on the sound will depend on which way you need to move the crutch. Make sure you have a little oil on the pallet faces and pivot holes.

      Is this a 'hack' ?

      By oldhippy · Posted

      I need to see photos of the whole movement before I comment.

      Omega cal. 565 - low amplitude

      By swiss2k · Posted

      Hi @Jon, so, from one extreme to another the beat error is 0.1(min.pos) to 0.2(msx.pos), and as you mentioned the rate does up and down dramatically. Also checked the position of the collet, and the collet is not central to the jewel on the balance cock. Balance moves freely, per my understanding.   So, after 24h the ampl. fell down by approx 20 deg, which I would assume is expected. After adjusting the endshake I believe I gained around +10 deg. of balance movement. Which is great, and overall the balance is not at 220'ish deg.   What I did next, some might think is non-orthodox, but was wort a try. I too the mainspring out, checked again for endshake and if the pin moves freely, and cleaned everything. Usually when installing the mainspring I would use some barrel grease on the barrel walls, install the spring and put a 2-3 drops of D-5 oil on top of the wounded spring and in the places where the arbor sits. This time I took the spring and applied a ultra this coat of Molykote Dx paste on the whole spring, before installing it in to the barrel, and added some oil to the arbor as usual.  The result improved, at a full wound the balance produces about 230-237 deg. @JohnR725 I'm getting closer to 300 😃   What I am noticing, there is a fluctuation in amplitude. With time it would rise and drop about total 8-10 deg in an interval about 2 minutes. I assumed this ruled out the power transfer from the barrel itself. So I took the gear train out, cleaned and lubed.

      Balance spring fell out of regulator pin.

      Thank you so much, Hector and CJ. I appreciate the tech sheet and the video. Gasp, I think I will make the attempt. What's the worst that can happen? I think there may be a new balance complete in my future, though.  I'll update the post and let you know the result. R, Frank

      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? Here is the fake .pdf for just the FreeCAD base file and 3mf files Modular Movement Holder.pdf Here is the fake pdf for complete set of the new base and ring FreeCAD/3mf files: Modular Movement Holder base and ring v 2.1.pdf However, I'm wondering how often you could use this feature, adding the dial usually increases the OD of the movement, so you would need a new (larger) adapter ring tuned to the OD of the dial and I wouldn't like to grip the dial in any kind of movement holder if It could be avoided for fear of damaging it. Maybe I'm misunderstanding you?

      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.
