Wing Profiling Advice

I recall a picture or diagram of the tool for measuring
surface deflection. It may have been in one of Dick
Johnsons articles which are or were available at the
SSA web site. Iif not it was written up in Soaring.

Thanks to all for the input and theories. I'm going
to go find/build a wave guage and measure the depth
of all these emerging imperfections and report back
here. My ship arrived with perfect skin, the blemishes
didn't arrive until 'puberty' (age 18-20 months --
this year).

Anybody able to point me to a source and/or plans to
make a wing wave guage?

Thanks!

Larry,
The dimples you see are from holes in the foam core
that allow resin to penetrate the foam and insure a
good bond between the cloth and core. Usually don't
cause a performance problem.

Some ships are perfect and stay that way, others go
to hell in no time at all. Ever wonder why? We have
a 27 here in Northern California that is absolutely
perfect and it shows. It's owner just won the 18 meter
nats with it.
