discard the apron and move the bass bridge forward as far as the plate will
allow which would allow the backscale length some improvement. Yes, the
bass strings would be a bit shorter but you'd gain back scale length. The mono

On one of the two As I did last year I did what I call a partial float at the
end of the tenor bridge which was done by drawing a line from one end of the
maple cap piece on the board to the other end, installing a small rib on the
bottom underneath the line and a thin maple strip over it on the top for a
little reinforcing. I made the cut after the auxiliary ribs were
on.<BR> </STRONG><SPAN class=531183711-09082002><FONT face=Arial
