    Any particular tricks to get a pendulum further away from the weights so that it doesn't hit them? Movement is 451-050A. Not sure if they come with different post lengths. Thanks!

    Yes, you can buy these in several different lengths. I usually go digging in the ole scrap pile.

    How much farther do you need the pendulum to hang? Some times a new hole can be drilled and gain almost a quarter inch.

    As a last resort, you can get some chunks of teflon an push
    the chains or cables off a little to clear. You can mount them
    to the bottom of the seat board. You can't get much this way
    with cables but chains are relatively forgiving.
    Modifying the pendulum post is another option, as a last resort.
    The correct diameter weights is the right way.

    The diameter of the weight shells is about 1 3/4". I am switching around pendulums on two grandfather clocks as I suspect the pendulums were replacements (one too long, one too short).

    Well if the pendulum might have been replaced. The bob maybe to thick

    Is it possible you clock could be leaning forward or back? Though you might expect both weights and pendulum to remain parallel to each other they might not

    Mounted at different heights, they would be parallel but not the same
    distance apart. They have to be real close to start with to end up touching
    on any typical angle for a tall clock.
    Tilting forward would make them closer, assuming the pendulum was
    mounted higher to the back.
