    I'm curious why is there a notch on the strike side main spring on a Gilbert Movement? Is there a real reason for it? Is it suppose to be there? If so where can you obtain it? Where can you find out the length of the needed spring for a Gilbert Movement? It was my first Antique Clock. A beautiful large Porcelain Gilbert case is in perfect condition. I would be more than greatful for any conversation or help with this matter. Hooked on Clocks ever since I got her.

    Hi Ryan, and welcome to the message board.

    I'm sorry but I can't picture in my mind a notch on the side of the strike side mainspring, as I don't have a loose Gilbert movement here right now to look at, and am not sure which Gilbert movement you have. Could you post a picture of both the spring and the movement?

    Ryan, you are not going to get any response until you post a picture because we/I do not know what you are talking about.

    Hi, Ryan, welcome to the message board. If you have the spring, the best way to find its measurements is to measure it. You will need a micrometer for the thickness. As mentioned, a few pictures of what you have are needed to give you much help.

    Hmmm. It's been National Gilbert Month around here lately--I've had four or five of them, of various vintages, and I don't really understand what you mean by that notch. Could it be possible that you're thinking of the countwheel, which is located on the same shaft as the strike main wheel in most Gilberts? This looks like a regular brass gear, but it has slits in it.

    The steel mainspring itself shouldn't have any notches in it, for that would invite breakage. Please post a picture, and someone will be glad to help.

    Here's a couple of views of a movement I restored for a Gilbert china clock. Does it look like yours? Can you ID the part in question from it? (BTW, I didn't do the solder on the rack, and it was later removed and cleaned up :))
