Pre-close? Other than setting the top skin on and shaping for a good fit,
I'm not sure what you are speaking of.

Let me know how it comes out Mike. I have quick-build flaps and after I got
the skin on, noticed that one was a little long. I checked it and it was
about 3/8 longer than it should have been so my day has been spent shortening
it. I filled the outside ends of the flaps and ailerons.
Are you doing a "pre" close before the final bonding? Bob Berube suggested
that I do so and I'm glad I did.

Thanks Jim,
I did drill those holes for pressure relief. I also added some extra
plywood/fiberglass support around the triangle area at the wing root due to
concerns
of the skin flexing while people are entering or exiting the plane. I have
quadruple checked for no tools or spare nuts & bolts and have cleaned,
scuffed, and cleaned again the contact areas. Will epoxy today. Am using the
10'
long piece of square tubing, clamps, and a bunch of my dive weights to insure
good contact.

Mike-
I have the identical setup that you do and just did my skins last week. If
you look in the build manual, it seems to say that you don't use the pacers
under the ailerons. I didn't and I will need to trim more skin than I want to
to get the required up aileron. If I was going to do it again, I'd probably
use the spacers under both aileron and flaps. To attach the spacers, we cut
several pieces of packating tape, used a yellow hilighter to draw the line
on the flaps, dropped the flaps, I then held each depressor in place while my
wife put the tape across it to hold it in place. When they were all on, we
ran a couple of thicknesses of packtaging tape the length of the flap to hold
the spacers in place.
Gotchas: Don't forget to drill the hole for pressure relief in the last rib
on the outboard end. Also, it does not mention it in the manual but I
notice that there is a triangular shaped area on the inboard end of the wing
that
will also be sealed. It is rather small, so may not be a problem, but I'd
probably want to put a hole in that rib too for pressure relief. Make sure
the MW-4 rod ends are installed on the aileron bellcrank before closing and
have at least two other people confirm that you have not left any tools in the
wing before closing. You may also want to mix the Araldite a little thicker
than usual so it will "stick to your ribs" (bad pun). Last, don't forget to
scuff sand both surfaces well. We just used bricks for weights and it all
went fine.
Let us know how it goes.

Good day All,
I have a quick question.......would those people that have already bonded
their top wing skins give their opinion as to the build manual using stir
sticks as a spacer when bonding on the top skin? Is their thickness the right
amount? If I remember correctly, my stir sticks measure about .070" thick.
Thanks in advance.
