Now here is an interesting thought

Hi again Calin.

The long side was glued and the front was of course glued to the rail, 
and the short stretch of straight length of the treble side was morticed 
and glued into the case. The entire curved part of the bent side was 
held in place by a piece of moulding nailed down into the rim. You can 
see the holes where the nails came through the soundboard edge in the 
pics.  Half of the tail was floating and had a substantial piece of wood 
glued to both top and bottom side... presumbably a mass addition to 
store and return some of the vibration of the panel.  The other half was 
nailed down with a piece of moulding like the bent side.

    Hi Ric,

    I'm not sure I understand how that soundboard was mounted. What part
    of it
    was glued down? You mean the whole edge at the bentside is not
    glued? Maybe
    you should make a drawing :-)
    Was the part where the bass bridge ends floating?
    Do you have any pictures from before disassembly?
