Broken Hitch Pin

	A couple more details that have occurred to me - maybe obvious, maybe not.
1) Measure neighboring hitchpins with a micrometer to determine the correct 
diameter drill bit and replacement pin. Note they may not all be the same. 
Steinway B's, eg, alternate two thin, then one thick in the mid treble (for 
spacing purposes).
2) It's a friction fit, but the pin should be the same diameter as the 
hole, not a few thousandths larger. If anything, pin should be a bit 
thinner than the hole. Don't worry, it will hold as long as the diameters 
are reasonably close, due to wedging pressure when the string is installed. 
If the hole is so much larger than the pin that it feels loose - due to 
lack of matching drill size and pin material - a bit of CA should be 
sufficient.
