There has been some empirical evidence that letting the distal end of the
pin stick below the sound board is beneficial, although my take is that it
makes little difference. What is important is that you should avoid having
all the pins bottoming out with the tips digging into the wood at the
bottom. Likewise, be careful that the pins do not stick into the sound
board, unless you are fond of sound board cracks.
The fit of the pin should be quite snug, but not so snug that you need to
pound it in.
Keep in mind that our bridge pins are also piano action centre pins, and
are available in different diameters, in case your holes turn out to be a
bit not snug enough.
