[pianotech] cracked/split jack birdseyes, etc.

[Richard W. Bushey]

Joe,

Thanks, Joe.  I'd love to learn this repair method, but I think I need a bit 
more clarification to be sure I'm understanding you correctly.

You said drill "across" the centerpin hole. So I'm assuming you mean 
perpendicular to the original hole and intersecting the original pin hole, 
and are not referring to just "cleaning" out the damaged (basically an 
enlarged hole in the bird's eye on one side) centerpin hole with a larger 
bit (to the size of a round toothpick), plugging the entire pin hole, then 
redrilling?

If you're not referring to plugging the entire hole and redrilling, I may 
need a pic to show what you're referring to.

If you ARE referring to a standard plugging and redrilling, I did think of 
that as an option in a pinch, but was concerned that after it was plugged, 
how to drill the hole straight (square, whatever) so I didn't duplicate the 
problem I already had, which was the jack operating crooked. If this is what 
you do, do you have any trouble with that, or do you just eye ball it as 
best you can when drilling? Pin vise drill I'm assuming. I suppose one could 
hold something square against the jack as a visual guide.

Thanks.
