Susan, This is exactly what happens. The CA glue becomes solid, like cement, and holds the pin. You basically fill up the crack with the stuff, let it cure for a few minutes, and it does the trick. On the grand, gravity was a helper. If you could somehow tilt the upright so the bridge were horizontal, it would really help. --kwgm Kurt W.G.

If there is plenty of space, and plenty of both glues, it turns to a sort of hard froth. I haven't checked over time to see if it hardens further in a day or more. If the CA has wicked into the holes, it shouldn't end up being goopy, but should turn to a pretty hard material. The question is whether a thin smear of white glue to quicken its set time would end up gummy. Maybe not ... or possibly, it might be easy to remove later. I doubt that the white glue would penetrate the CA past the surface of the bridge, but who knows? I think I have a hunk of bridge off an old, long-dead piano. If I can find it, I'll try experimenting with it, and see what I get. Regards, Susan
