<DIV><FONT size=2></FONT><FONT face=Arial color=#000000>Am I missing
something? Why and when is it necessary to change hitch pins in a cast
iron plate unless they have been broken or damaged. I've refinished
several hundred plates and, to my knowledge, the one's I've replaced I can
still count on one hand. They are there for the life of the piano.
Regarding the last post on the SAT, if you have to ask what charger replacement
you should use, I still insist you send it back to Sanderson because you WILL be
the one who reverses the polarity, and if it's been serviced lately, they would
be glad to replace a charger, reasonably, after making sure you have the latest
software and hardware upgrades...still makes the best sense on an instrument of
this nature..</FONT></DIV>

Farrell<BR>> <BR>> David Hughes wasn't asking about vertical hitches. He's
<BR>> replacing originals with new and shiny. But since it was <BR>>
brought up, drilling through the middle of the old pin is one <BR>> of the
best ways ever invented to break bits. If you can't get <BR>> the old pin
out, and don't have room on the riser to move to <BR>> virgin territory,
grind them off flush and center punch the <BR>> back edge. Drilling
vertically, you are taking out some of the <BR>> pin, and some of the plate,
but the bottom of the pin is out <BR>> of the way and still embedded in iron
so it won't turn and <BR>> grab the bit. As always, at least two passes. One
undersize, <BR>> and one ream to final.<BR>> Ron N<BR>> <BR>>
