Craig's Guitar
Frets
I made the head and bridge out of a lump of old
redgum fence post. The nut was brass, the saddle aluminium. I was keen
to avoid the deadening effects of plastic. Even the scratch plate was
made from New South Wales Rosewood rather than plastic. Usually
a guitar fretboard is made of ebony for its wear resistance, while the
neck is formed from a lighter, cheaper hardwood. However, I had picked
up a lump of solid ebony substantial enough to form the entire neck.
Ebony is not a local timber (I couldn't get ironwood, my first choice),
but is so outstandingly dense that I had to use a hacksaw to cut it.
Strength and stability would prevent warping and assist sustain. I
calculated the fret spacings and marked them off by sight with a metal
ruler. This seemed pretty crude, and it worried me a bit. I'd heard
of a commercial guitar maker using computer-guided equipment to get
the frets positioned perfectly, and there I was, eyeballing them. I
wondered if my guitar would play in tune. I also wondered if it would
collapse when I strung it up. The tension of metal guitar strings totals
over 40 kg (100 lbs).
