It's been some time since I completed this task but as I recall it was
pretty straight forward. I started at the root tip and worked towards
the trailing edge outboard trim tab. Firstly, I laid out my roll of bid
and using masking tape I made patterns for each piece of cloth. I used
1/2" wide tape that when cut down the middle made a nice 1/4" border all
around the cloth (this is not necessary on the hinge plys as they are
pretty small and easy to work with). The advantage of this method is
that is keeps the bid from stretching in any one direction. After I
prepared the cloth I then wet out all the pieces required for the first
layer (three pieces I believe- tip to root) on Saran Wrap - plastic
wrap. I then transferred the cloth with the plastic wrap on it to the
Tail plane. Once the cloth is in place and you are please with it remove
the plastic wrap. When you get to the servo trailing edge tip use a
mixing stick or squeege to gently push the cloth into this very tight
area. It is not as difficult as it may seem. Note: the plastic wrap is
still on at this stage. Again, when you are satisfied with the layup
remove the wrap. As you are working against the clock you may consider
trimming the cloth after every second layer, trimming two plys at once.
One last note, I found it much easier start with the tail plane resting
on the tip for the root close out, however I repositioned it to rest on
the leading edge once I started the trailing edge closeout and then back
to resting it on the tip for the servo tip closeout.
Good luck.
