Rib Thinning

[Richard Brekne]

Hi folks

Finished trimming and sanding down the ribs for the soundboard of this 
old C.C.Lose square and went to see how it fit into the <<rim>> of the 
instrument. I noticed right away it had shrunk down quite a bit.. Of 
course it has a slight crown to it now, but that isnt going  subtract 
much. Looks to have shrunk in cross grain about 6-7 mm at its widest (60 
cm). There is still enough to get a  decent enough bite on the rim, but 
it was a tight fit coming out. So the question is... is it advisable to 
add a little strip on one of the edges so that the cross grain width of 
this panel fits tight going in dry ? Or is it advisable to leave things 
as they are.. Centered, each edge has about  5 mm of panel over the 
edges of  the rim on either side.

Thanks for any advices,

RicB
