A pneumatic damper of the [normally vicious] gravity arm re-latch
is not rocket science. [G&J]
A roller re-latch is also much gentler process. [Shortt FP]
Magnetic effects from iron back plates and closely mounted
electromagnets has been discussed in the past. [HJ?]
Brass is not hideously expensive in the sizes required.
Particularly at "tame" scrap dealer prices.
Flexure of the base frame at the flimsy suspension chops is
another grey area.
The mounting of the Synchronome movement in such a flimsy case,
using only a couple of short wood screws, has long been a matter
of concern in precision circles.
Why cling to any Synchronome basics when all of its
"theoretical foibles" can be relatively easily addressed mechanically?
Any connection between century-old theory and the original master
clock is completely severed by modern electronics.
Surely the real challenge would to make a mechanical
amalgam of all the successful master clocks?
Adding electronics produces a Zanzibar Fallacy that you are
actually doing something useful to improve the Synchronome's
timekeeping.
When you are really putting a dumb monitor on the weight tray. One
whom chucks stuff on and off, to frantic, external, hand
movements.
Or was that the Gents' Observatory Transmitter? Now that was a
work of true genius! ;-)
