Plate bolt question

[Ron Boyd]

Geoff......Randy Potter has a good method described in his video
"Intermediate Repairing Techniques". If the bolt is stripped install "C"
clamps on both sides of the bolt so the plate doesn't move out and than
drill out the hole so it goes completely out the back of the piano. You than
install a bolt with nuts and washers and pull it up tight. I would think you
would use stainless steel for the bolt and washers so they don't rust.

Robin --

I, too, use the screwdriver tips that fit into my tuning hammer. Very
convenient. I have only been going after the hidden screws when I find that
the accessible screws need more than just a nudge to tighten them up. And
even then I've only gone for the ones that aren't totally hidden. Loosening
the strings to get to those is something I just sort of didn't want to think
about. Perhaps I should the next time I feel the need to get that
aggressive.

I can honestly say I have never actually stripped one of these screws out.
But I do find them stripped out occasionally. My first reaction when I find
this is to wonder how anyone could actually strip out screws that are that
big. And then I wonder if they might not have been stripped out at the
factory level. I do find the occasional new piano with plate and action
mounting screws stripped. Action mounting screws I can fix easily by gluing
in a piece of wood, (NOT toothpicks). But, (see question 2), is that an
acceptable way to repair stripped plate screws?

Geoff,
I'm with David I. about that; don't sweat the understring ones....UNLESS you
are noticing a tuning stability problem or unless you're finding the easy to
reach ones obviously in need of a turn. In those cases, bite the bullet and
loose just enough strings just enough to get the screwdriver onto the
screw/bolt. More work up front but often less in the long run. I often use
those big Phillips and flathead screwdriver tips that fit into the tuning
hammer. I got for very snug, but not ridiculously so. No need to
gratuitiously strip screws, LOL.
