June 2008 : Meeting Report
Practical Demonstration.
This is a meeting which we eagerly await each year, a practical demonstration by Keith Davis. The subject this year was 'Dial Matting'. There are differing ways of achieving the 'matt' finish but clearly Keith prefers the method produced with a roller. The tool that Keith demonstrated was about 18 inches long and it consisted of a long wooden handle extending to a steel frame with 3 loose discs at the end. The discs had a series of hardened points similar to saw teeth. By applying heavy hand pressure the wheels were moved back and forth over the surface to be matted, which was finally brushed with a wire brush to remove the metal dust.
In preparing the surface, Keith recommended that this should be scraped initially. For this purpose, he used an old file bent over to form a hook, and achieved a flat surface through scraping in different directions.
Working the metal in this manner causes some distortion and the dial will need to be flattened again and ultimately the surface will need to be finished off with wet and dry paper.
This is not a task to be carried out in a hurry and should be done in short bursts, as it is quite tiring. It does also need a lot of practice in order to achieve the best results.
The afternoon continued with a barrage of questions, sometimes drifting a little off the subject — but that only made for an even more enjoyable afternoon.
December 2008 : Meeting Report
Bring & Discuss.
The meeting was held as usual at the Community Hall in Vintners Park Maidstone and was attended by some forty enthusiasts. Items presented included readings from old horological tomes demonstrating yet again that pride of ownership and arguments about such were as alive a couple of centuries ago as they are today; electric clocks and motors of different ages showing that early construction methods and principles have stood the test of time; and wooden printing blocks which had been used and modified slightly at a later date to be used again, the latter subject relating to the use of advertising print blocks which were modified when new products became available.
A small but very weighty turret clock ticked sonorously away during the meeting and caused a slight stir when the strike sounded at three o'clock (a gentle click-click-click), followed by the fly overrunning on its ratchet (quite a loud clatter!) as it slowed down.
Two early (c. 1690 and 1715) verge bracket clocks by Windmills and Robin were eagerly examined after the formal presentations, as was a magnificent Lorch watchmaker's lathe with all its accessories in its box. Two dipleidoscopes were also on show and their application was discussed at length.
The history and exploits of a Mercer ship's chronometer were presented, giving the dates of its various voyages and repair time in the Admiralty workshops. The voyages were detailed with the number of the convoys it travelled with and the ships it was later issued to, together with photographs of the vessels. A second small turret clock was described, having been constructed by the member, using a grasshopper escapement as detailed by Lord Grimthorpe in an early article on the system.
A vote of thanks to the contributors by David Presgrave was carried enthusiastically by acclamation and the meeting concluded with the customary Christmas fare.
