Folks - see my journal entry & linked pictures for 16 November 2007 
for a graphic illustration of this on my port wing - go to 
<http://home.clara.net/rowil/aviation/200711.html>
I've just done the starboard wing in the past week and it displayed a 
different set of rib height variations, so pre-bonding was definitely 
worthwhile for me.
I endorse Neville's advice about using the strip of vinyl as a spacer 
too - anything thinner would have needed excessive trimming to get my 
aileron travel up to spec.
Hope this helps.
regards
Rowland
