    Default Inconsistent hammer drop

    I have this here Ingraham that I've just finished servicing, and it has an ailment: The strike hammer drop is inconsistent, randomly. Sometimes it hits the gong with a satisfying Bong!, sometimes a weak ding, most of the time it doesn't contact the gong at all.

    My theory is that it has to do with the way the hammer is activated by the lifting pins on the maintenance wheel...but I can't figure out how that could be. The hammer never fails to lift, but it only hits the gong randomly. I've tried the usual business of Bending Things, but it hasn't touched the problem.

    Before I go tearing this puppy apart again, I thought I'd ask y'all what you think might be going on.

    Well, I think your hammer spring needs adjustin Bong....!!

    More than 'adjusting' I'm afraid. I believe this is the model that has just a short tail that hooks around the center post. Very easy to forget to hook it during assembly and a devil to hook after assembly. (been there done that)

    If the spring is there and tensed, you might look for the
    lever dragging on something. Since the levers are flat
    they can get bent towards or away from the front and back
    plates.
    You might be able to see such by looking from the sides or top.
    I think it is just the spring though.

    HAH! Found it.

    Spring was okay, but hammer was loose on its arbor. A drop of Loctite fixed it.

    Thanks for the suggestions. You got me looking in the right area of the clock.

    Certainly, I cannot even imagine the hell it was clock repair before they invented Loctite...
    Great you fixed that hammer at last

    Which Loctite product did you use? The shock loading of a hammer drop will be a real test for it.
