Kundo 400 day clock suspension spring.

[escabena]

Good morning, a friend of mine left me this watch to recover it(it will probably remain in my collection....). As you can see in the pics , the suspension has passed away,spring is toast. The rest of the watch is surprisingly fine. 
I have been reviewing and reading the messages on this forum about this type of watches and I know that the The Horolovar 400-Day Clock Repair Guide book is the bible for my question but for now I cannot make this investment at the moment . 
Can you help me by telling me what would be the reference of the spring to buy and the right length of the spring and the blocks and the position of the fork for the pallets? (the measurements for the fitting of the suspension spring) 
The measurements of the plate are 70 mm high and 43.68 mm wide.

If you need any more information, tell me.

P.d: that horrendous plastic tube should be eliminated, I know.

Thank you very much in advance.

 

Miguel.

Hi it looks like it's a minlature clock called a torsion clock or better known as an anniversary clock.

Plate 1406H you would need a spring unit 5C, 5D, or 5E which is recommended.

Don't know where you would buy one in Spin in UK Counsin's sell them 

Year c1970 good luck.

Thank you very much Willow. 5C,5D and 5E are .058 mm, right? For some specific clock issues it´s difficult to locate a seller in Spain (although they probably exist but I cannot locate them). Now I have to see if I can find the distances between the fitting of the suspension spring.

Best regards.

Hi    from the top of the top block to the bottom of the bottom block  95mm according to Twilligers book.  the thickness of the spring is the important factor,  length no so much. As its a torsion pendulum it is the rotational speed that controls the rate.

Thank you very much watchweasol. While confirming this data I have been cleaning the mechanical machinery, the base, etc. I am entertained while I continue reading information about these types of watches.

Best regards

I´m seeing/reading that the complicated issue in these clocks is setting time. The easy task for now is cleaning the machine...Now I understand Willow's good luck . I have already ordered the suspension spring on eBay. I will take advantage of the time to continue learning things about this type of clocks. There are quite a few threads in this forum.

Best regards

Good morning everyone, first step completed. I received the suspension with your instructions and with great care I managed to place it in its place. It spins well without stopping. I notice that the escape wheel does not move although the anchor does swing. I understand that I need to adjust the saddle something to fix this problem , anyway I have to continue observing it and review forum topics.
I still have many things to learn about this type of clocks.

Best regards.

 

Miguel.

Have you done a complete disassembly and thorough cleaning yet? The movement needs to be really clean to work properly.

These clocks work best on very little oil. It has already been pointer out with these clocks it it always best to under take a complete service. This tool is extremely good for adjusting the beat of the clock, it has to be in beat if not the clock will stop.

Hello Hectorlooi, yes, I did, and I also put tiny drops of oil. I also checked that everything turned well before mounting the pendulum suspension spring.

It's probably the problem because it has actually stopped. I will review what you tell me oldhippy. (With the tool you tell me the list of Christmas gifts is starting to get long )

Thanks

How do you actually use this tool? I normally just turn the screw on top.

[escabena]

I was thinking the same thing because my clock also has a screw on top....

[watchweasol]

Hi. The tool clamps on to the top suspension block, which is tightened enough to allow a little movement and adjusted left or right

depending on how the anchor is locking. Micrometer adjustment with this tool. I have both the tool and instructions so will try and get them scanned nd posted.

Hello again, I´ve  already fixed the problem with the escape wheel. I verified that even without the pendulum it rotated correctly, so I dismantled the anchor and checked everything again until I verified that with a little force from the mainspring it was already working correctly. Then I put everything back together and there it is, working. I'll leave it like this for a while and then adjust the beat.
