One of the problems of being a largely self-taught clock restorer is that you have to learn more by making mistakes that if you were learning at the feet of an established master.

A mistake I have now made more then once is not to secure the taper pin holding the hands in place sufficiently tightly. This has now bitten me again. When resetting the hands of my Henri Marc I noticed that both the pin and the washer behind it were missing and there was no sign of them on the mantelpiece or the hearth below which in any event would have been hoovered two days ago by our cleaner.

I now need to make a new washer, which will be good practice on the lathe, but I can't remember exactly what the original one looked like or was made of. Should I use steel, then blacken it to match the hands, or brass? Unfortunately I don't have any clear photos of the clock before the mishap.

Two of my French clocks have flat brass washers, the other 2 have domed steel washer. I guess you can pick what you like. When there is little space between the minute hand and the hole for the pin a flat washer will be easier to fit. These washers are tiny and rather thin. I doubt that the Timesavers 100 pack will have these sizes. Best to make one (or several) yourself.

i’ve flattened many a domed washer in my vise... and also thinned them using 600/2000 wet/dry sandpaper. one size does not fit all. :)

To keep the pin in place you can 'scarify' it by turning it in any type drill or pin vise.
While turning the pin, pinch a folded piece of about 150 sandpaper firmly against it's surface, just for a second. Long ago some smaller tapered pins actually came this way. It makes a big difference in whether they stay or go.

Did you try the ole vacuum cleaner & stocking method? This is where you cover the open pipe with a piece of stocking or nylon mesh curtain material and give it a go. Make sure you go out for at least 10 feet in all possible directions. :)

Curtain material? You'll find a good supply of material in your wife's undies drawer. We won't tell :D

Timesavers, domed hand washer, black, (also in brass), #23786 100 in pack, you may need that many. :D

Nigel,

As you are in the UK I suggest you buy from Meadows & Passmore or one of the other British supply houses. But you could just go to your local clock repairman - he will have washers and pins in plenty and might just give you some.
