    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...

    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may be largely original to the clock but the carving is probably Victorian i.e. done 100 years or more after it was originally made.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...

    Fusee verge re-conversion help

    Single train clocks with a dummy second winding hole are not unknown and it might be worth exploring whether this was originally the case with yours. If so, it would have been subject to a substantial rebuild to add a striking train as well as a conversion to anchor. The large hole in the...

    Fusee verge re-conversion help

    I have spent most of the last year self isolating in rural Kent, away from my clock workshop in London. I received the vaccination earlier this week so I hope to be able to get back to my clocks before too long.

    Fusee verge re-conversion help

    I am trying to do something similar with a clock from about 1710 which is missing its quarter repeat, its alarm and its verge escapement. I have never done anything like it before and have been recording my adventure, largely put on ice during the COVID pandemic because of the closure of my...

    3 Weight GF clock pendulum stops

    A heavier pendulum perhaps?

    Comtoise clock ca. 1830 verge movement runs but stops every few hours

    Double striking is something I have not come across myself. From the video it looks like it has a rack rather than a count wheel and the rack is located between the plates (unusual - normally it would be between the front plate and dial). Normally a rack striking would be triggered via a two...

    Comtoise clock ca. 1830 verge movement runs but stops every few hours

    Judging from the video the clock is significantly out of beat. The "tick" and the "tock" should be evenly spaced in time. This can usually be cured by bending the arm of the pendulum crutch.

    Comtoise clock ca. 1830 verge movement runs but stops every few hours

    Excess oil should not cause gears to slip. The main problem with excess oil is that it attracts dirt which accelerates wear. Slippage is more likely caused by the gear/pinion being damaged or excessively worn or the pivot holes being too big, or both. If the latter they should be bushed and...

    Reopening clock and watch workshop post COVID?

    Our club has a separate workshop for watches and clocks and members who are interested in watches form a different demographic - generally much younger and fitter. The watch workshop is the one we hope to reopen first, subject to the trustees' approval once we have finalised our proposals...

    Reopening clock and watch workshop post COVID?

    We have been using Zoom during the lockdown. Not all members have taken to it but it has enabled the club to continue providing a service to members. Our reopening plans are coming along quite well but we are not quite there yet.

    Reopening clock and watch workshop post COVID?

    As a trustee of a horology centre just outside London - an educational charity run by volunteers which operates as a membership organisation - I have been asked to chair a working group to determine whether and how we can safely reopen our clock and watch workshop which has been closed since the...

    A couple of lathe questions

    I am a recent convert to using collets, especially for making small clock arbors with a graver, but I appreciate your dilemma. They can be rare and are almost always very expensive. At home I have a Cowells which takes 8mm collets (£70+ or so new) and a Myford ML10. Myford has its own collet...

    Finishing pivots

    My inexperience in horology is taking its toll. Yesterday I nearly ruined my third attempt at making a replacement arbor with integral pinion when turning the pivot on one end. Fortunately my tutor stepped in to help. The arbor is made of silver steel. I left the pivot oversize when I...

    Articles on the composition of 17th and 18th C clock brass?

    Most interesting. I found this while searching for articles by Robey (his pamphlet for the British Museum on ferrous metallurgy in clocks is available but at a very fancy price): http://www.bhioxbranch.co.uk/mans_early_use_of_metals.pdf

    Articles on the composition of 17th and 18th C clock brass?

    I have just spoken to the supplier of the cast yellow brass sheet I used to make the wheel blank. He tells me it was 60% copper, 2.7% lead and the remainder zinc. He also recommended a caster in Devon whom I had separately identified someone who could make my castings.

    Articles on the composition of 17th and 18th C clock brass?

    I am currently having difficulty finding a foundry I can trust to cast parts in the right colour brass. I have just received some casting from one firm which are far too pink, having been assured that they would look the same as "yellow clock brass". In reply to a (very polite in the...

    Why Not Oil?

    The lantern pinions often don't use a hard enough steel.
