I am sure one of you will Know why on a number of German clocks is there a large R ↓ A on the pendulum?
This appears on many clocks Retard or Advance R – A
Just like Slow or Fast S – F
Clockmaking – Cornelia & George de Fossard
Cornelia and George de Fossard’s recently constructed miniature longcase clock appeared on the front cover of the February horological journal. Please join us as Cornelia and George take us on what promises to be a fascinating journey into modern-day clockmaking.
Cornelia served an apprenticeship to a carpenter and cabinet maker in Germany before heading to the UK to further her skills at West Dean college near Chichester. Now self-employed as a furniture restorer, she has an extensive range of of skills including carving, gilding and turning to mention just three.
George served a four year apprenticeship in mechanical engineering then went on to read Mechanical Design, Materials and Manufacture at the University of Nottingham. After a spell working in design engineering, he re-trained as a clockmaker at West Dean College.
George and Cornelia now run a business together based in Frome, Somerset specialising in the design and manufacture of fine quality handmade clocks. Cornelia also undertakes the conservation and restoration of early English furniture and clock cases.
Please note that the next meeting will be held at the Endeavour.
It is across the road from the White Hart Barn.
Head straight across, keeping the pond on your right, the venue should be on the left.
Music Boxes and Automata – Ted Brown
Have you ever been fascinated by mechanical music automata or novelties?
It is most likely if you love clocks watches you will have come across such items either included in a musical clock or watch. Mechanical music has been celebrated and used long before the pendulum was introduced to horology.
Our speaker this month has taken his fascination for Mechanical Music boxes to a higher level. The highly respected Ted Brown has been collecting all of his life assembling a small museum of these Victorian artefacts. He will bring along a selection from his collection and talk to us on Music Boxes, Small Automata, and Novelties. Ted does not normally talk on his subject outside of his museum.
Following one of our visits last year, to a private collection of clocks music boxes and cars, Ted has offered to give us a guided tour of his collection at “The Victorian Music Room” later this year. Ted will discuss methods of restoration and repair and is happy to answer any technical questions we may have.
South London Branch member, Antonio Silva, sent these pictures of a carriage clock with savage two-pin lever escapement that had been on his bench recently. When he started to dismantle the platform escapement, he was surprised to find a red powdery deposit that had built up around the balance staff and lever. At first he thought it might be polishing compound such as rouge.
On closer inspection it turned out that one of the two pins on the roller had been replaced with a polished steel pin and through constant contact with the steel lever had worn and the subsequent dust had oxidized into powdery rust.
The pins on the Savage escapement were usually gold and do wear and so it is normal to see replacements but, from this example, it is clear that steel replacements are not a good idea.
Our March meeting was somewhat of a break from the norm, with a series of practical demonstrations from a number of branch members. Thanks to the wonders of technology, the demonstrations were (almost entirely) projected onto a large screen for the audience’s convenience.
Maurice Fagg – a video demonstration of re-pivoting a watch pinion
Duncan Grieg – turning on the clockmakers’ throw
James Marten – using a clock mainspring winder
Ron Rose – using the piercing saw
Alan White – the construction and use of an electronic dividing tool
A morning’s trawl of youtube very quickly turned up some fascinating short films about watchmaking. Here are just three:
And just in case you need an antidote to the smooth voice-over actors – here is a video from the swatch group featuring the late Nicolas Hayek about recreating the Marie Antoinette watch, which at the time had been stolen and apparently lost forever.
Our last meeting was given by Mr John Warner from Burgess Hill a member of the Sussex branch of the BHI and the AHS.
John comes from a chemical engineering background and lived in Rhodesia working for subsidiaries of Fisons and ICI. He served in both the Rhodesian Air Force and the Rhodesian Army against Robert Mugabe. Relocating to England in the 1980’s he has been a Company Director and a Management Consultant. He turned his horological interests from a hobby to a vocation and he is now a full-time watch and clock restorer. In association with Thwaites and Reed, has worked professionally on some very famous clocks.
