French ormolu clock restoration.

Below you can see a French clock which came in for restoration this clock has missing parts such as one wing from the cherub and two wings from the butterfly at the front, these parts have to be made using the lost wax principle.

These items are then added to the clock which is then gilded.

Below you can see the two wings which have been remade and fitted to the butterfly, the clock has been gilded in 24 carat gold.

These French clocks often have items such as the dial and side panels which are painted and enamelled these items are very often broken we repair these in such a way as that one would never ever know they have been broken.

In the picture below on the left you can see a broken enamelled panel.

And in the picture on the right the repaired and enamel panel inserted into the gilded clock.

Grandfather clock or long case restoration work undertaken on the case work.

This oak long case clock hood came in for restoration without the rest of the clock as this was broken by a removal company who decided to have it repaired hopefully after they had informed the client.

Round mouldings of this sort are very hard to reproduce partly because they were scratched with a blade To the profile in what is known as a scratch stock.

This device is a right angled device like a set square with a slit in it that takes the metal profile with which the timber is cut to the shape and then scratched, the timber then has to be stained and coloured and aged to match the surrounding service.

Walnut Longcase Clock by Williamson of London circa 1680

A fine walnut long case clock with features as used by the famous maker Thomas Tompion. This clock came to our workshop in a rather sorry condition after falling to the ground. Below you can see a picture of the damage as photographed by the client.

Broken Walnut Longcase Clock by Williamson of London circa 1680

As you can see the clock has fallen apart. This is partly due to the weight of the clock as they are made from oak then veneered over with walnut and after a period of time the glue on the blocks holding the case together crystallises and looses its adhersion. The movement has received a heavy knock and is badly bent and broken.

After this restoration work, the clock should look in original condition as if it had been looked after and polished and loved for years. Below you can see photographs of the finished clock in the clients house.

The insurance value of these clocks generally exceeds £20,000 therefore they are certainly worth having restored well.

A clock rather similar to this was sold by P A Oxley in Wiltshire for £22,500

Fine French mantel clock circa 1840

We were called to London one-day to look at a clock that had fallen to the floor. This clock was rather important as it was bequeathed to the property from Lincoln's estate.

This clock was in a particularly bad way, the dial was broken and the movement had a bent winding shaft and the main shaft arbor was missing completely, the movement also had other broken wheels and shafts, the marble base was also broken and cracked.

Below you can see photographs of the item as we received it in a box, prior to restoration.

Bent and damaged French movement enamel dial

On the photograph on the left you see in the centre that the main arbour is broken and missing you can also see the bent shaft which corresponds with the damage on the dial in the photograph on the right just below the 3 o'clock.

Below you can see damage to the marble of the clock.

damaged Onyx

Repairing marble is often quite complicated particularly matching old marble because it has some age associated with it then of course one has to cut it and mould it.

Below you can see an example of the finished movement, dial and marble case.

French Gilded Ormolu Clock

I was contacted by client who said they had a fire and their clock was damaged.

Below you can see pictures of this clock prior to restoration, the clock is covered in verdigris and rust.

clock dial before restoration

This clock was burnt and then soaked by fireman, then left for approx a year of time before restoration was agreed by the insurance company.

Gilt clock before restoration movement before restoration

In the pictures above you can see the condition of the clock, the movement on the right was covered in rust and verdigris and builders rubble and apparently the firemen had used the clock at some stage as a doorstop.

The movement was so rusted all the pivots had to be remade and most of the bushes had to be replaced. Most metal parts had to have the rust pitting removed and the brass cleaned to remove verdigris. The case was disassembled and each part cleaned thoroughly and then gilded using the electrolytic process.

The glass from the dial was removed using very hot water which expands the bezel. The bezel was then cleaned ready for gilding.

When this clock was originally made it was gilded using mercury but we cannot do that these days as the law does not allow it.

The brass case is cleaned and then a copper flashing is put upon the surface, it is then gilded in 24 carat gold.

Clock movement after restoration

Below and above you can see a picture of the movement after intense cleaning and restoration work.

Close-up of clock movement after restoration

The case is reassembled and the gilded bezel again reheated in hot water and the glass re-added to the bezel.

After all the work on the movement is undertaken, and after final cleaning the movement is reassembled and tested. Below you can see photographs of the finished gilded clock.

Minor repairs to complete restoration...

We pride ourselves in what we call "invisible" repairs. This means that if we have restored an antique table, chair or a clock case you should not be able to see where the repair has been carried out.

When we undertaken a repair we often correct previous repairs that may work, but are simply incorrect or unsightly and will if not corrected will definitely devalue the clock.

Below on the left you can see a photograph of a long case clock movement circa 1780 with a missing date wheel and wheel post. These date wheel arrangements were often removed as they are famous for having all sorts of problems associated with them. The snail has been removed for clarity.

On the right you can see the same eight day long case clock movement with a date wheel made and fitted. This has to correspond with the snail and a seconds wheel which is fitted to the movement dial.

Below is a picture of a long case clock movement with a poor attempt at previous repairs. Soft solder has been used to make repairs and other parts have simply been bashed and dented by a hammer.

long case clock movement prior to restoration

The Snail above will have to be replaced as you can see a piece of brass has been added to the edge of the one o'clock position, that is to the top left of the picture. This has been soft soldered badly and the rest of the snail is also misshapen therefore the striking sequence is irregular. You can also see the wheel below this is the date wheel.
