In the course of building a new A-6, I wanted to pre-shrink the condenser paper (from a method suggested by Bill Gowan) and noticed that the paper shrank a considerable amount (not surprising really, that's the whole point!).It made me think that the weight per sqr/in value should have gone up as a result. I weighed a few 110 and 120 sqr/in pieces and found that the post shrinkage weight was now 0.00695 grams/sqr/in or 15.8% heavier than before shrinking (0.006/grams/sqr/in).This can make a difference to an A-6 with a 50 % stab area of 0.04275 grams (45 sqr/in total flat area only) and a bit more if dihedral or tiplets are added in.
I've not seen this mentioned before so I thought I'd share.
