The volume control is a linux utility and shows signal strength after the preamp. It was fed into a laptop headset socket via a splitter lead. This is a stable trace off a new Seiko. A 15 year old chronometer usually doesn't give such a stable trace, it's running 15secs a day slow. It still seems to get the timing error correct despite this and playing around with position may give a more stable trace. Any new watch so far does give a stable trace.
General bits bought off amazon UK. The pickup is intended for a violin.
Seems to be 2 problems. Bandwidth of the electronics, too high with an amp like this and probably similar, the mechanical aspects of the pickup. Unfortunately commercial microphones for this use are rather expensive.
If anyone else tries to install on Linux I found that the automated build wouldn't work but the usual ./config etc did and indicated what lib files I needed to install.
Hello all!
When regulating and adjusting a watch we have to close the regulating pins as much as possible around the hairspring, leaving a minimal space between them and it when the balance is in the neutral position (neutral position being achieved only by taking out the anker/pallets).
My question:
After making all the settings on the regulator (for timing) and the end-stud (for beat error) why couldn't we close the regulating pins all the way around the hairspring? Why do we have to leave a small space on the left and right of the hairspring (if we add up these two spaces we have to get no more then the hairspring thickness or less then that).
Could anyone provide more details on the phenomenon behind this thing? Maybe even a mathematical/physical explanation?
Thanks! I've seen Mark showing how he oils a mainspring of a hand winded watch, but I have not seen any showing him doing it on an automatic. He then shows all of the oiling spots, goes through them one by one, but never shows or mentions what he does to the mainspring. If I am wrong about it then I will stand corrected.
Pre-oiling the mainspring, just like you do with the (lint-free) tissue paper, will cause, when the spring is wound with a mainspring winder, for the oil to spread up all the way to the place that should get no oil at all. There will be no way to prevent it.
I have read in a few places that the 1900 will read co axial escapements.
If anyone would care to send me a George Daniels or Omega I'll gladly check that and video it for you all to see.
This tends to be a personal preference thing.
With modern white metal UB mainsprings, theoretically they don't need lubrication. Most people however do, Mark himself does but just doesn't show it on every video. There is one or two where he demonstrates how he does it.
Personally I use a small piece of tissue paper to apply a thin smear of light grease rather than oil. Others fit the spring and apply 2 or 3 drops of oil which then spread through capillary action.
I've wondered about regulating a watch myself and came across this. There are other pages about as well.
