Restoring crown in old soundboard

[Hotwheelsp at aol.com]

As I have progressed through my first restoration, I have now come to  
repairing the soundboard. After inspecting it for cracks (there was only one  which 
traversed the upper left corner), I turned my attention to the crown of  the 
board. My question now is: How do I restore crown to this old board. Is  this 
possible? The board has negative downbearing, which I guess could  be corrected 
through the soon-to-be recapped bridges, but I figured this  was not the long 
term solution. Any advice would be greatly  appreciated
