A selection of images showing some of the servicing and repair processes

Some stages in the re-bushing of a spring barrel. This includes making new bushings for the barrel itself and the cap, boring the barrel and cap concentrically to accept the new bushings, riveting them in place and machining them to be concentric with the great wheel.

A carriage clock service. All parts are dis-assembled, including the platform escapement. The pallet fork and balance jewels are visible here.

Making a new threaded rod and rating nut for an English Dial clock. The original was so worn as to allow the heavy pendulum bob to fall off.

Re-hooking a mainspring. First image shows stress cracking in the hooking eye. The end is annealed, a new hooking is formed and the spring installed.

Some more work on an English Dial clock. Installation of a new fusee line (steel at owner's request), some dial indices and numerals were restored.

A three-train Mantel clock service. A minor repair was made to the wheel driving the chime cams was necessary. Finally, the clock is on initial bench test.

Re-pivoting a fly arbor. Only 0.5mm diameter, this is the smallest pivot on the clock. A guide is used to drill the arbor precisely concentrically. "Blue pivot steel" is used to replace the pivot itself and turned to the finished diameter.

Here, a lovely Vienna Regulator was restored. The Harrison maintaining power needed repair, a new pin and screw were made.

More work on a Vienna Regulator. The escape wheel teeth needed refinishing and the pallets were reground to the correct angles using a specially made jig.

These show a new crutch pin and beat setting being made. Also weight pulleys with steel bearing sleeves and new shouldered screws blued to match.

Once the clock is finished, it is "brought to time" by iterating the rating adjustment initially over a few hours and finally days. A graph is produced of the recording.

After bringing to time, the clock is regulated over a period of weeks by recording the error and correcting for it.

The data are used in an Excel spreadsheet for further analysis. All this informaton is provided to the customer, together with a full record of the work.

Please feel free to call or email if you'd like any more information on the above, or indeed other matters horological.

Stages in replacing a wheel tooth. A fillet is made, soldered in and filed to the exact shape of the existing teeth. The result is an invisible repair.

A snail for rack striking made from scratch. Starting from a disc machined to thickness, through measuring the rack pitch and calculating the snail pitch to the finished part.
