Excellent stuff there, Mark!

 

I did a no. 3 trim to the beard recently and brought it right down to whiskers - so you're now ahead of me in the beard length. Still, it's spring, and I expect a full growth from both of us in a few days more...

Just clipped it all away. I am a strange fellow - if I close shave I end up itching all day, if I let it grow too long I end up itching. I usually clip with no attachment.

 

Will - you must feel bald at the moment!

Great vid!

Not to be ungreatfull, don't get me wrong, I understand the long hours spent behind making these videos, but I am waiting for more advanced stuff! More like those two hairspring works you've done :)

 

For example: adjusting in different positions, centering the hairspring between the regulator pins,  static and dynamic poising, pivots streightening and polishing, pallet stones repair and adjustement  :)

 

Again, thank you very much for your work spent doing these videos!

:) I understand - I have had a huge amount of requests for regulating and timing machine content.

So it is good to create a mixture of basic and advanced content but at the moment I am doing a series on the basics and will work up from there because it is laying foundations for some of the examples you would like to see.

 

I really appreciate the feedback Bogdan :)

"Normal haircut"... :D

 

Twice a year for me - and sometimes three if the weather's exceptionally warm.

Mine is a race between going bald or silver, the baldness has been accelerated after tackling hairsprings & crawling around the floor looking for lost parts.

Good video as usual, and nice animations. :)

 

What I miss though is an explanation of why it's good to be in beat. It's not obvious to me why being out of beat would necessarily be a bad thing. The balance wheel still oscillates with the same frequency.

 

I have read that being out of beat affects the rate in different positions and that makes some sense. But I've also heard that it will make it harder for the balance wheel to start up and that it decreases the amplitude by wasting power…

Splitting hairs, I have a remark on this excellent new video.

My attempts at setting beat with the stud movement puts the watch out of time. So I readjust the curb pin setting using the timing regulator and this invariably results in a new, but smaller, beat error. After some iterations I can usually arrive at a watch in beat to within a few tenths of a ms and timing good to second/day. But it always needs three or more iterations. Is this normal?

As I understand it a low beat error is important when the watch mainspring winds down, but in a auto watch it is not such a issue.

I could be wrong but also if out of beat in certain positions the out of beat would become an issue.

I don,t understand how by altering the curb pins I can change the beat or am I missing something.

Two potential problems if a watch is not in beat: Beat error can possibly cause positional error in vertical positions. The watch may require agitation for it to start because the impulse jewel is not in the correct position. A watch wildly out of beat may be difficult to start or may stop intermittently. You may have amplitude problems.

But yes, you are correct. The overall time it takes for an oscillation should remain constant.

A goal would be to keep beat error to under .5 milliseconds.

      Epilame / Fixodrop

      By Knebo · Posted

      I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.

      Coil for old Seiko Credor -- 4002920

      By Neverenoughwatches · Posted

      There are some parts on Ebay for the seiko 6020A, it may just be a waiting game for someone to strip one down, NOS will be more scarce . K would strip your movement down to the module then start looking at other seiko movement to see if that coil is used, then seek out a seiko part dealer. Also Retrowatches youtube owner Mike may give you some advice try him on his site . He also hangs around amateur watchmaking groups.

      I would agree, in order to work harden something you need to exceed it's yield strength when it moves from the elastic zone to the plastic zone and you get permanent deformation and work hardening which is fairly close to its failure point, relatively speaking and dependent on the material/alloy of course. In theory you can load something constantly within its elastic range and not suffer work hardening issues.

      Probably easier to get a complete new movement - but CousinsUK list it as discontinued. Maybe someone on here knows a substitute movement ?

      Any other thoughts on how I can get a replacement coil? Any “hidden” or unknown physical shops (in Australia or elsewhere) that might have them in stock (but not always online)?
