    This is the striking mechanism of a grandfather clock I'm repairing. Is there a piece missing? (Gathering pallet?)

    Many thanks for any help.

    Yes, the gathering pallet is missing. One can see the empty square arbor to which it should be attached.

    Thank you Uhralt. I'm guessing one has to make a replacement? Is there any help here on how to go about doing that?

    You can buy blanks that you would need to finish to the exact dimensions you need for your clock so that it meshes correctly with the rake. It is easier than making one from scratch.

    How would one go about making such a tiny square hole in the gathering pallet blank? Are there files that small? Or does one broach it?

    Thanks

    I have done this by using a square needle file as a broach and hammer it into a starter hole in the work piece. Hammer it in, turn it upside down and hammer the file out, insert from the other other side, repeat until the proper size is achieved.

    The gathering pallets available here in the US seem to have a small round hole which could be "squared" using a very small square file or a jeweler's saw with a small blade. Commercially I think the square holes are made using a square broach that is pressed down, similar to the process how the square winding holes of clock keys are made. You could try to make such a broach, but I don't know how realistic that approach is.

    You could also "cheat" and use a piece of a pocket watch key with a fitting square and enlarge the round hole in the pallet to accept the piece of the key stem with a tight friction fit.

    Thanks David and Uhralt; that's very helpful. The squared end on my clock seems tiny…and it's tapered so I'm guessing the piercing saw may be the best option.
