| Subject: | Rib stitching question |
2 1/2" spacing pulls the fabric up against the ribs in the under camber area on
the bottom of the wing. 3 1/2" spacing leaves a little gap between stitches.
Is it worth making that area 2 1/2" spacing to avoid that gap?

Aren't you using Stewart System glue? I glued my ribs to the fabric
prior to applying the reinforcement tapes and rib stitching.

Look at the rib stitching and hi-speed tape starting at 1:08 of this video. It's
a good reminder (to me, anyway), of how much force is pulling on that fabric,
which in turn is pulling on those stitches. Gentle climbing turn, under 70 mph:
https://www.youtube.com/watch?v=ZdcKXbX8eVw
I'd stitch closely (2.5" vs 3.5") and follow other instructions from the fabric
system manufacturer. This may be being overly cautious, but separation of fabric
from structure has occurred, and with deadly outcomes:

Like many factors in building the answer is"it depends".
I used the PolyFiber process and in their process if I remember correctly (I
did this over 10 years ago), they had you glue the fabric to the ribs, then
heat shrink at 250 degrees, then rib stitch, then do the 300 and 350 degree
shrinks.
Read and FOLLOW the manual for whatever process you are using. If they
manual doesn't cover how to do undercambered wings, call their customer
support line and ask them. Use their resources, not someone on an email
list that may or may not be familiar with their process.
Good Luck!

Thanks, Jack. Great advice on all points. I will be using the Stewart System and
will follow all their directions. I am still on schedule to start covering in
December. Looking forward to it.
