Soundboards are braced using an adaptation of standard guitar cross-bracing with
added tone bars which are tapered individually to suit the particular soundboard.
The aim is for a balanced tone across bass and treble. The back is traditionally
ladder-braced. The instruments are fitted with non-adjustable truss rods as I feel
that the short scale length of a mandolin does not require an adjustable rod, but
the addition of the rod helps balance the mandolin and may help sustain.
I have experimented with various finishes including French polishing, varnishes and
wax finishes. My aim is to protect and enhance the instrument while not deadening
the tone. I really like French polish on traditional instruments but for a working
instrument this finish can be a bit fragile and players often prefer and ask for
a wax or oiled finish. Recent experiments with Behlen products are encouraging.
