400 day clock suspension spring


Willow

Recommended Posts

Well I have seen some springs but that.s the best yet as Nicklesilver said "toast".  The double ended key is from a clock with a brocot escapement (visible escapement) and the small end is used to adjust the pendulum length from the front. There is usually a small hole above the 12 marker and a small arbour to raise or lower the pendulum.    I have attached a picture of what the spring should look like.

If you order only the spring u will need dimensions from the Horolovar 400 day clock repair guide. Or from anywhere else if you can get it. You could take the measurements of the existing one but because the spring is twisted it is probably a bit shorter now. You will need to post a picture of the backplate for us to identify your movement. I could try to scan the right page for you but, I am not an experienced guy, my first 400 day clock is still on my bench waiting for me.

Hi when you come to assemble the suspension  be very careful with the spring as they kink easy, attach the top and bottom blocks as per the drawing as per page 179  5E (use Horolovar springs as the book is based on their research)  and when satisfied they match then fit the fork. Once satisfied assemble the suspension to the clock and fit the rotorary pendulum and set up.  If you have the tool as old hippy mentioned it makes it easier as you are able to make miniscule adjustments.  Make sure the clock is level and the pendulum is directly on center at rest above the cup. On page 56 there is a grid for you to copy and use for setting the overswing / beat. Once you have set it up and working you will be hooked on 400day clocks   I love them  and have several plus some quartz ones. The wife likes them  they dont TICK  TOCK.

Be sparse when it comes to oiling the movement. They perform better. A good tip is to oil the inside of the pallet fork on each side where it makes contact with the stem of the pallets, nothing more then using your fine watch oilier should be enough.  it also will prevent any fluttering. (fluttering) when many escape teeth escape at the same time.

Have ordered the spring I have just got to figure out how to get the pin out at the bottom without causing any damage my wife is the same no noise and no striking in the middle of the night?

If you mean the pin in the bottom block, there is no need to remove it, just unscrew the two screws, remove the old spring, insert the new so it is touching the pin, make sure it is all proper to the diagram in the book and screw tight. I found a good way of fitting these springs and screwing it tight was to use my watch vice to hold the blocks in, Be very careful with the pallet fork when screwing it tight do not kink the spring.

    • HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....  
    • Hi there, welcome here.  
    • yes the advertising revenue should generate money. The question is how much money? Then as far as the cost of the website goes that's relatively easy to determine? all you would have to do to grasp costs and profitability would be to go to the link below and you can actually get a website for free try it out for free I believe you get no advertising initially. They also talk about that they'll help you out they have marketing tools and some sort of paid subscription or something. So I guess were shopping for a whatever just ask them what would a maybe could use this one as an example in other words it's going to look basically identical to this is going to have advertising a paid subscriptions what's it going to cost? After all they want to sell or give us a message board like this they should bill answer the questions as they're the people who did the software for this. Yes they really said you can have a free discussion group at least to start. https://invisioncommunity.com/ I was curious about the monthly supporter thing where exactly do we find that on this message board? A quick search I'm not finding it so obviously I'm not looking in the right place?
    • Help me out here, but with all the advertising on this site (which I don't mind) wouldn't it pay for itself or even make money for the owner ???
