You will need a helping hand when your ready to actually glue the leading
edge cover to the nose ribs.
You cannot see it in these pictures but if you think about the way the
ribs are placed over the spars there is a one quarter inch difference between
the top of the rib and the top of the spar. This is because the spar
is constructed using a one quarter square strip of wood called a cap strip.
If you glue this leading edge cover on the wing and attach it to the nose
ribs and the spar you will have a gap produced by the difference of the
tops of the ribs and the tops of the spar. This is why a gluing strip
must be attached to the top of the spar between each of the ribs.
When the leading edge cover is pulled down by one person, the other person
tacks the cover to this gluing strip. Of course the glue
was applied before any of these components have been tacked down.
I must have these photos out of series because if you look at this
leading edge cover, it extends past the spar. Earlier you have seen
how we cut the cover so that it covers but does not extend past the spar.
Pulling this down in this picture is also how the marks are placed on the
cover for final cutting prior to gluing and tacking.
If you have read all of these photos in sequence, you will see that
I too am learning every time I make and review one of these web pages. |
