    Intermittent flutter consistent?

    What is interesting here is that the clock was running so well before it was shipped. I have seen just how finicky they can be when just shifting the time by an hour "seems" to upset them. Therefore shipping them to another location is a very big deal! Note the word "seems" here. Its so easy to...

    Kundo won't stay running

    You have done really well and I can identify totally with the emotional side of fixing things that have a personal sentimental value. Never mind about the help which also gives pleasure the givers, just count your luck on getting such a good result at an early stage. That luck is only made...

    Kundo won't stay running

    Of course you're quite right about that Wayne. Its the challenge. I have had "drives" to improve my own collection of 400 day models. It worked for a while but only for months rather than a year. I'm talking about timekeeping primarily. They have it in them to be very good. As you say - brass is...

    Kundo won't stay running

    Wayne et al; That's a wonderful madness that you have there. A glutton for punishment and more torture. Unless and until someone dreams up a simple interlock that will prevent flutter - I will resist more mechanical torsions. How come the Atmos claims are so good? Its a heavy disc type...

    Oh Wayne - don't they just. {Multiply). I think they even argue with each other in the night. They certainly gang up on me. Best rgds. BerryG

    Kundo won't stay running

    RJDJ2000 All the people of this Forum have been so generous and encouraging to me. I feel a debt like you do. If we can only encourage its something. I have moved on to encompass the strikers and chimers, alarms and 36hr jobs, the watches too when I don't shake too much, as well as the 400 day...

    Kundo won't stay running

    Everything needs to be spot on before you start. There's so little latitude and that's what makes them hard work. You're asking for a year of operation from a pretty ordinary size of mainspring. Quite apart from driving the escapement, the hands have to turn all those days from a single...

    Fluttering

    Ha Ha! Oh you gotta laugh. A bit of string...... Thanks for that response Nathan S. It turns out that the length of the suspension spring has a quite tiny effect on the rate. Its thickness works contra to common sense, and flutter is like the work of a leprechaun. Thirty day regulators do at...

    Fluttering

    Reading through my post of yesterday I find myself wanting to expand or edit it slightly. Narrowing down the cause of flutter is one thing. A cure is something different. I think we are talking here about the power in the system matching to the natural rotation and furling / unfurling of the...

    Fluttering

    I just gotta say that it has been my experience that these clocks are always on the edge of flutter. Its a most misleading phenomenon as the clock can be rated to go slowly and use the random flutter to make up the lost time. It is therefore not truly isochronous. We can ask if that matters and...

    Horolovar and thousands of suspension springs

    Hi David, - Thanks for the response. Be very careful with those pin-pallets. They snap off like carrots if you're at all heavy handed! I am certainly not an "expert" but over these last few years I have had hands on with many of the post-war "novelty" variety that were a favourite amongst our...

    Horolovar and thousands of suspension springs

    Love your post expressing that same old agony I feel myself. I especially like your adapted quote on insanity...... It fits the bill on every level. Ga! Ga! Rgds, BerryG

    Horolovar and thousands of suspension springs

    Ha! Ha! That's a crimping tool yeah? Useless for crimping but as a beat setting tool absolutely the dogs B. !! Is that a Kundo or Schatz Miniature in your picture? I think I see an anchor with solid pallets. Have you any experience of beat setting a Kern & Sohne Midget variety? They have pin...

    Horolovar and thousands of suspension springs

    Is there a use for torsion held weights (pendulums?) in earthquake detection? I can say, as as I'm sure many of you can, that 400 day clocks are very susceptible to subsonic vibration even when mounted on the sturdiest shelf. Seismic Motion - is that the term? Sounds painful eh!

    Kundo flutter

    That very succinctly describes my experience Schatznut. Thanks. At first I struggled so much that I would have, and did for a while, settle for the clocks just maintaining their operation and their fascination. However, just prior to reading your posts I was motivated to try the flutter damper...

    Kundo flutter

    Thanks for that thorough response. I'm on top of everything you mentioned except the mainspring. I haven't got a spring winder so I can only wash it out and re-lube it. I have some thin synthetic oil that I use. I wonder if that's the common link to my failure? I do the cleaning and test for...

    Kundo flutter

    Thanks for the response Schatznut. it is much appreciated. I was helped here on this Forum some 4 years ago when I was tackling my first Torsion clock. I had much to learn and owe a great deal such people as John Hubby, Bangster, Victor Miranda, Kurt and several others towards whom I feel a...

    Kundo flutter

    Sometimes I have been able to eradicate flutter by adjustment only to see it return after a few weeks of running. Even with monthly mid-winding it appears. Yes the smaller ones are worse. The K&S mini - all awful! The Haller & Schatz 53 (approx18cm) are taller but much better. I do not own a...

    Kundo flutter

    This subject will come up for s long as we have mechanical torsion clocks. There are many weird issues. I cannot come to the table with many answers - BUT I do have many fulfilled and unfulfilled questions. Its knowing how to phrase them and in what order that's the problem. Starting with the...
