Plate Pin Problems

[Farrell]

The holes I have seen are drilled straight, as are the new ones I have made. Friction holds the pin in place. If I run across a slightly loose one and I don't want to change its location, I can either use a bigger diameter pin (center and front rail pins work fine), or I have also put a dab of thick epoxy in to fill whatever gap there might be between the fit of the pin in the plate.

When I drill a new one, I drill on the angle I want the pin.

Never had one pop out.

Hello,

I don't believe the hole in the plate is cone shaped, but others have may be
better understanding than me.

Once hammered, I had no problem with the 2 pins I changed yet (but I had
them from Steinway).

May be it is better to glue the pin or use CA. When popping out the old pin
may be enlarge the hole a bit ?

I can't see why pins may be bend, the hole may be slightly angled I presume,
but I remember noticing bend pins on some cheap pianos.

Regards.

  Thanks ... But how do you properly insert new pins? Are they ALL the same
size (Schaff 5/8" by .157)? All the pins on this Hamilton Studio are bent in
the middle--normal?  Is there anything holding the pin other than friction?

    Hello,

    It happens if the string is not at the base of the pin sometime, mostly
if there is a large angle from there.
    It is important to tap the new string (as old ones sometime) down at the
base of the pin with a brass rod and a little hammer.
    Plate pins are not bent usually, but is it really a plate pin you
installed ?

    May be you were not using the good string size (or someone before you)

    Hope that helps.

      Thought I had a broken treble string today. took out the old one only
to find it wasn't broken. Looking closer .... no plate pin. Gone. Popped
out.

      Okay, found the old one--all bent and boogered up. Got out new one.
Gently pounded it in using 2 1/2 # hammer and tuning pin punch. Used large
screwdriver and hammer from up above to bend the pin down, somewhat.
Installed string. Up ... up... up... near pitch ... up ... uuuup ....
TWANGGGGGG.

      Okay, so I don't know how to install a new plate pin. And scared of
breaking the plate with too much whapping and tapping.

      Would greatly appreciate a brief lesson, here.

      Thanks in advance.
