[rebel-builders] RE: Wing cut-outs for fuel tanks.
Posted: Sun Feb 19, 2012 11:42 am
Bill: The way I interpret the manual and having built two sets of wings this
way is this:-- The side cut out allows for two rows of rivets to join the
wing skin with the tank skin just outside of the last solid tank rib and
rear bulkheads on the top skin, where as the back side allows only one row
of rivets to join the tank and wing skin just past the rear bulkheads on the
bottom skin. This is so the tank skin is resting only on the solid rib and
rear bulkheads to help create better sealing. The double row following rib
direction or cord of the wing is necessary to carry the compression loads
during flight. The tank skins are placed over the uncut wing skins during
the build process and all is drilled at one time making the wing skin cutout
easier to see after disassembly. I hope this helps some what and is not to
confusing. There are no actual dimensions as the cut outs are determined by
maintaining the 5/16 edge distance shown in the manual. Bob J

cut-outs for the wing tanks? I have e-mailed and phoned MAM with no reply
in the past five days. I need to know the location of the lines parallel
to
the tank bulkheads for both the top and bottom skins. I don't find it very
clear at all in the manual. It is shown in figure 10.10.12 section 0.10
Wing Assembly. The diagram doesn't show the line of rivet holes for the
tank bulkheads as far as I can see. Does anyone have an approximate
distance from the leading or trailing edge of the skin?Bill Londry
