<DIV></DIV>Hi all,<BR> <BR>I want to experiment with using ebony bridge
caps in the top section of the treble in my pianos. <BR> <BR>I have
taken sample pieces of ebony and attempted to notch them by hand
with disastrous results. Ebony is so hard and brittle that it wants to
chip and split, even with the sharpest of chisels and shallow cuts. I've
approached it from the top down and by coming in from the side. The side
cutting method works well with Hornbeam, but doesn't seem to do well with the
harder ebony. Do any of you master woodworkers have any suggestions
(short of not using ebony 8-) )? <BR> <BR>I know that most of
the companies who are using ebony caps have machine notching devices. I
prefer doing things by hand, especially bridge work, because I'm concerned
about controlling the accuracy of a router type notching machine. But if
anyone has successfully made their own "notching machine" and would be willing
to share their experiences and/or has plans for such a devise, I would welcome
any comments or advice. <BR> <BR>Thanks in
advance,<BR>Michael<BR><BR><BR>
