Re: [T3] Brake Pads


I've had success by spraying the mechanical parts with WD40 - I believe its role
is to thin the original lubricant that has become sticky.  Don't flush (eg soak
in WD40) unless you are convinced the face etc will be unaffected.

This is about the only 'repair' possible.  I believe in some cases the very fine
wires of the coils get corroded by flux used to solder them to the small circuit
board.  Unless you have micro-soldering skills, I think it's unlikely you'll
make a successful repair to that.  In another case the pendulum had rubbed the
surface of the coils and worn through.
It is possible with ingenuity and removal of the back-plate to adapt the clock
to use a cheap quartz movement.  I've done it as a functioning mock-up, while
another club member adapted his clock in a similar way and has it running in his
Type 3.  If the original fault is terminal, I see no objection to such butchery!

The transistor is biassed to conduct, and one set of coils attracts the
pendulum.  This movement induces a back emf in the other coil, which changes the
bias on the transistor base to stop it conducting, so the pendulum returns and
the cycle repeats.

We're talking about the later clock with transistorised movement (generally
black-faced, but rarely grey).
