    Dividing Head for Mill

    Mr Tompion and others made some pretty nice clocks without CNC, but it certainly makes life easier. During the COVID lockdown I have been unable to access my club's workshop so finally got round to investing in some more kit for my home workshop. My club has an electronic indexer mounted on a...

    Any info on Samuel Smith of Newcastle?

    Thomas, John and Joseph Swinnerton. My maternal grandmother was a Swinnerton, descended from John. Clocks by signed by Thomas and Joseph seem to be more common than those signed by their brother.

    Any info on Samuel Smith of Newcastle?

    Newcastle under Lyme in Staffordshire had an significant clock making industry in the 18th century. An ancestor of mine was one of three brothers who were clockmakers there in the late 17th and early 18th century. I have a lantern clock c.1680 signed by his older brother.

    Longcase Restoration Project

    The case may be largely original to the clock but the carving is probably Victorian i.e. done 100 years or more after it was originally made. The hood does not look quite right and may have been altered, the swan neck pediment moulding in particular looks wrong and the turned pillars may be...

    Restoring matting on brass dial clocks

    Looking closely at mine it seems it was done with a square punch. The slightly flattened area is next to the the hour hand, and hidden by it in the "before" photo. I suppose one could try making a similar punch?

    Restoring matting on brass dial clocks

    Is it possible to restore the matting on old brass dial clock? The dial on one of mine has had some later holes plugged but the restorer left some scratch marks in the matting and one small area of matting is slightly flattened. The scratching is very light and only visible when the light...

    1710 Etherington Table clock with lots of bits missing

    Just had an email from my dial and case restorer. Both are finished. The mechanism restoration is more or less designed and some tooling up has been achieved but I am far from completing it.

    1710 Etherington Table clock with lots of bits missing

    Used my Vertex rotary table today with an ER32 collet chuck mounted on it to slash the teeth on my first gear cutter. Stages of cutter development shown in second piucture, alongside a commercial Thornton cutter. Still need to heat treat, polish and test.

    1710 Etherington Table clock with lots of bits missing

    Finally got back to making my gear cutters. To check the width and depth of the cutters I need to make I have looked again at the existing wheels. Teeth on clocks of this age are square bottomed and are formed with a more or less parallel sided cut, with the teeth only curved over at the top...

    1710 Etherington Table clock with lots of bits missing

    These photos compare the dials and under dial work of two Etherington clocks which I believe may be close in date. The first dial is more finely engraved and has four subsidiary dials with the alarm setting dial in the centre (clockwise from top left, strike/silent, rise and fall, day of the...

    1710 Etherington Table clock with lots of bits missing

    The Hobson book is a facsimile of a sketchbook kept for private use and never intended for publication plus some black and white photos of only reasonable quality. There is very little description and analysis and few if any of the mechanisms are described in full. Useful, certainly, but...

    1710 Etherington Table clock with lots of bits missing

    I did find a copy of the Hobson book and it has been useful. Production quality and photos are not up to modern standards however.

    1710 Etherington Table clock with lots of bits missing

    Another thing that all three of these appear to have in common is that the maximum rotation of the main quarter repeat arbor for any given sequence is about a quarter of a turn, which will occur when the time is between a quarter to the hour and the hour itself when three quarters will be...
