    Hi Chaps - I do not understand why the majority of long case clocks have a nail protruding on the inside of the front section of the cases, just below the pendulum doors?? I have often wondered why?! Can someone tell me the idea behind this? I recall one of my clocks needing rewinding once and because the weights were of large diameter and below the level of this nail, the centre weight got scraped on this nail! Does it serve a purpose?

    Perhaps to hang the key so it doesn't get lost? Seems it should be to the side and out of the way, but....

    not sure about 'the majority' but would assume for winding keys.

    when i get or work on a tall case clock, i make sure that if there is something for holding the winding key it doesn't interfere with anything else.

    yes, though I normally see them in the side. If you mean just above the case door on the inside this is the pivot for the turnbuckle that secured the hood door.

    Thanks Pat/Bruce, seems to make sense but these nails are found in weight driven (on chains) floor clocks?

    Thanks Novicetimekeeper... I have never seen one positioned above the pendulum door - all have been on the front of inside of cabinet below the pendulum doors (not to one side but in the middle?)
    I have removed these because sometimes the centre weight is too close when rewinding..
    I only work on used reproduction floor clocks that are no more than 40 years of age so unable to comment on the antique clocks..

    A nail on the inside of the clock just under the front of the door on the front inside the case. Usually is to secure the cables or the chains in transport to keep tension on them.

    Yes. I suppose it could also serve as a pendulum reference for setting beat. People were very inventive back in the day.
