Here's a quick interrupt to proceedings. Just received this grandfather clock for repair
According to my friends on the open clock club. It's a 18 early 18th century long case clock
Well made lovely pillars here
And it's got an hour
wheel
Support here, so a lovely piece of kit
Things wrong with it well
It wasn't working
One of the gut lines is missing
on this side here
we have a
Pendulum chime, which obviously has been
taped up to make sure it didn't make too much noise the
The hammer is actually attached to this strike arm with a blue tack and an old matchstick
So that needs to be put right

All the clock needed in the end was a very good clean
All the bushes were okay on all the wheels
so all I did was
Put the wheels through the ultrasonic cleaner
and brushed
Cleaned the rest of the components
The original chime bell was smaller than and it didn't meet the hammer
so I had to end up making a brass plate, which I attached to swing the
chime bell nearer to the hammer and
That meant I didn't have to make any alterations to the brass movement

Using my homemade test stand
And here we are back at the customer's house
the lovely looking movement in this case
and the customer was
Pleased to hear the sound of the ticking and the chiming and it's just as she remembers her mom's clock
performing many years ago
