hi, i need to cut a piece of ebony (a fretboard for a guitar) with a slight taper on both sides with a table saw... the cut is really important so it needs to be very exact, the ebony is slotted for the frets already so it has 22 small kerfs in it... i've been told that to avoid chipping or any tear out the saw blade has to be very well aligned and sharp... i know this is quite a bit to ask but if anyone can help me with this i would appreciate it so much... thanks for looking, jonny... p.s. i'm in raleigh thanks, again
