    I was asked by Bruce what work was involved in hand finishing laser cut blanks. I am neither the craftsman nor the photographer, but the pictures were especially produced at my request to document the process so that I could share them. I'm not even the customer!

    The blanks were produced from photographs I took of a set of hands on another longcase of a similar age. This clock came with 19th century hands, over 100 years out of style. I know a company that sells blanks but we could not find a set to suit so these were custom made.

    There are a lot of pics and a few notes at the end. The second hand was made from scratch, the hour and minute are the laser cut blanks.

    These notes were provided by Peter who did the work. He restores virtually all of my clocks.

    "I prefer to preheat the brass filings before adding the hand and continuing to GENTLY heat to very slowly bring to temp.. This is esp important with hands that vary a lot in their mass in different areas. Patience is vital! I also blue lacquer when finished which prevents rust ( and enhances the colour).
    Overall, including making a secs hand from scratch about 10 hours! ------ most in fettling and decorating the hour hand which is most complicated and has to be symmetrical too.. Some of the decorative nicks are inaccessible to files, and I use a graver to finish those awkward ones"

    Hi Nick,

    I like the way Peter holds the minute hand steady with panel pins in the wooden lathe for reducing the thickness by filing. He's done a super job with these hands. I also notice that he uses a Proxxon mini drill press; I must ask him about that when I see him on Wednesday.

    Regards,

    Graham

    We often talk about Scott's work on the cases, I thought Peter needed a thread. He has done a terrific job on the dial too.

    Yes very fine work and nicely documented. I was wondering if there were any pics of the second hand and the work on it? thanks for sharing, Joe

    The second hand was cut from sheet by hand and riveted to the pipe. I don't have any pics of that I'm afraid.

    It is amazing to see the hands come to life as they are changed from flat cut out pieces to finely detailed (fettled) but still looking balanced and then blued. The time spent to get there is clear.
