Hi Alan,
Sorry for the delay in replying, we have had a major glitch here with our
computer
system, nothing was coming, although a test message I sent from home appeared
to have made it ( I didn't get a non delivered note on my home computer).
Anyway, we are up and running again!
I can't remember how much detail on closing the wings I gave you , so here is my
latest procedeure.
Trim the aileron closeout flange to be 1/2'' wide (the part that bonds to the
top
skin).
Trim the flap closeout flange to 1/2''.
Cut the bond at the rear of the rib on the rib at half aileron span to let the
closeout be free, also do the same on the outer flange of the outrigger rib.
The vertical web at the inboard end of the aileron should be cut out to leave
a 1/4'' rim.
Cut the ''roof'' off of the aileron mass balance boxes, and bond them onto the
lower skin, centred on the balance arms, as per manual.
Cleco the top skin on, and scribe a line on the underside, useing the closeout
flanges as a guide, and cut off the exess, so the upper panel matches the
closeouts.
Cover the leading edge of the flap and aileron with 3 or 4mm kitchen floor
linolium
or similar, and rig the flaps fully up, and the aileron in neutral.
Glue the top skin on, with steel box section over the spar flange joint, and on
top of the flap and aileron joints, with enough weight to gently squeeze the
Redux out.Put a generous amount of Redux on the ribs, and make a fillet along
the closeout joints to enlarge the glue line to about 3/4'', the Redux should
be thickened with cotton flox to the ''just doesn't run'' state.
When fully cured (leave for three days), remove the ailerons and flaps, and
scuff
sand the inside of the mass balance boxes, and the underside of the upper panel,
and do a 3 ply Bid lay up from the box onto the skin.
When you remove the lino' you will have a uniform gap.Sand the aileron
closeout/skin
edge at an angle, to match the required up deflection of the aileron.
This works every time, I did the last one this week.
Hope this will help, phone me on 1751 433475 if you need to talk this through,
sorry again about the delay.
Cheers,
Nev.

Appreciate the advice, however the closeout at the root was approximately
45MM while my aileron's are both 60 MM finished. The outboard end varied on
both the wings. I've quiried the factory as 15MM difference is a little much
for a factory fastbuild. Thanks
