I've never seen a split or crack that was "wide enough to shim".  You 
have to make it wide enough by dragging out wood to provide a narrow 
V-shaped groove to press the sliver into, and the best time to do the 
work is when the soundboard has as low moisture content as it will 
ever experience. -- like right now in Scotland, for instance.  But 
this work, from the look of your pictures can't be done properly 
without removing the iron frame.
