For instance, if it is necessary to
support the lifting surface, then the packing should be
arranged to come directly under the struts so that they may
take the stress in the form of compression for which they are
designed. Such supports should be covered with soft packing
in order to prevent the fabric from becoming damaged.
When pulling an aeroplane along, if possible, pull from
the top of the undercarriage struts. If necessary to pull
from elsewhere, then do so by grasping the interplane struts
as low down as possible.
Never lay fabric-covered parts upon a concrete floor.
Any slight movement will cause the fabric to scrape over the
floor with resultant damage.
Struts, spars, etc., should never be left about the floor,
as in such position they are likely to become scored. I
have already explained the importance of protecting the outside
fibres of the wood. Remember also that wood becomes
distorted easily. This particularly applies to interplane
struts. If there are no proper racks to stand them in, then
the best plan is to lean them up against the wall in as near a
vertical position as possible.
TIME.--Learn to know the time necessary to complete
any of the various rigging jobs. This is really important.
Ignorance of this will lead to bitter disappointments in civil
life; and, where Service flying is concerned, it will, to say the
least of it, earn unpopularity with senior officers, and fail to
develop respect and good work where men are concerned.
