Savage two-pin lever escapement

01South 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.04

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.

March meeting – practical demonstrations

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.

Demonstrations:

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

Three watchmaking videos

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.

February meeting – Thwaites & Reed

 

Our last meeting was given by Mr John Warner from Burgess Hill a member of the Sussex branch of the BHI and the AHS.

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.

 

 

Clockmaking in East Grinstead – exhibition

In amongst the pile of flyers advertising fast food, double glazing etc. at SLBBHI towers this month was this horological gem and we thought it best to share.
