shimmed tuning pins

[John Ross]

To stop the sandpaper from going into the hole, as I tap in the pin. I leave
1/2" above the hole, and cut it in 1/8" strips to the edge of the hole, and
fold it out. When the pin is in, I take my haemostats, and rip off the
strips. That way no sandpaper shows above the hole.
It is my preference to use a larger pin, since the time is less, and no
footering around. Unless the block is split, then the sandpaper and
possibly, epoxy are the way to go.

> I usually use 120 grit regular sandpaper. I have never had a problem with
the paper going down the hole. I make sure I have a bit of it extending
above the hole so I can see what is going on (although if it tore half way
down, I sure would not see that). If the pin was quite loose and other pins
are fairly tight, I will use a full wrap of sandpaper and come out somewhere
near the torque of the other pins. If the pin is loose and the others are
kinda loose, I will use a partial wrap and come out good. That's the
ticket - regulate end torque by considering the initial looseness and the
target tightness and use an appropriate percentage of wrap. No guidelines
for this though, just gotta experiment. A good feeling for it comes after
only a few pins though.
