Karl,

not being an aerodynamacist I would still strongly opt for going 'by the 
book' here !

I recall having to shave mine to achieve the nrs. For the weight lost I 
filled the previously filled holes and things were fine.

If you allow a relative shift f your deflections you'll end up with the 
stick being off-center all the time in the lightest case and with a 
unpredictable aeroplane in the worst case (if the offsets of both wings 
do not happen to coincide).

So, go shaving ! I am sure you had worse jobs 'a do. And I remember that 
feeling on fair-weather days that one could be in the air a little 
earlier at the price of less attention to detail. But refrain. She will 
pay it all back to you.

be well,

Thomas

  I am currently rigging my glider wings, hopefully for the last time. 
  In the workshop I measured the aileron down deflection to be 20 
degrees , it is supposed to be 20 down and 23 1/2 up.  Now I measure a 
maximum of 18 and 16 for down, and about 30 up.
  My question is : is it really important to stick to the figures in the 
book, or is it the sumtotal of up plus down when making a turn. These 
dreaded lead weights are the reason for the down restriction and I would 
prefer not having to shave them down.
  Any ideas ?
   
  Karl
