Before cutting away the damaged parts or ordering replacement sections, the proposed
method of repair, positioning of joint lines,
overlops etc. should be ascertained.
Determine a method for the correct positioning of replacement sections
and before
cutting away damoged parts check on any prominent features from which measurements
can be made and scribe these clearly on to the panels which are to be left intact.
Use masking tape or chalk to define the lines on which it
is
proposed to cut the
panels and study these lines thorough1
y
to see that:
(a)
any damoged or slightly damaged panel which would be useful in the
ali
g
nin
g
of another major panel will not be removed or,
(b)
on single skinned areas in particular the proposed outline traverses
longitudinal, lateral and
horizontal definition points to assist easy
lining up of the new panel in all three places.
When repairs have been carried out in the vicinity of the front wheelarches, ensure
the tyres do not foul the front lower flange when the wheels ore on full lock.
Undeneirl the wheelarch area to a de
p
th of
.l25
in
(3
mm) using
"3M"
material, or
its
equivalent
in
consistency, to prevent gel-cwt crazing caused by small stones etc.,
throwh
up
by
the wheels.
POSITIONING
REPLACEMENT PANELS
(a)
Line up
flat surface (e.g. undetry or floor area) using long wooden
beams bolted to undamaged area.
(ti)
Line up main contours (e.g. wing sections) using s
p
lints and bolt
into position with flat or curved steel straps.
BOBBINS
(METAL
INSERTS)
Considerable use is made of die
-
cast metal inserts, which ore oval in configuration
and commonly known as 'bobbins'
Thbe are designed to carry
high
loads in most directions and also offer the advantage
of
being accurately located in the mountings.
Two basic forms are employed as follows:
Large (structural) bobbins
-
with
3/8
in or
7/16
in holes (plain or threaded).
Sinall (semi
-
structural) bobbins
-
with
in or
5/16
in holes (plain or threaded).
The followin
g
advice is given on dealing with bobbiA hilures.
