BUILDING JIGS
Bi-planes are somewhat more complicated to
construct than a mono plane. This is due to the fact
that not only have the wings and tail plane got to align
properly, but each set of wings has to too. This is
made even trickier as the Camel has no dihedral on the
top wing but a significant angle to the bottom wings.
To help align all of the parts properly, VMC have
designed jigs to help with parts of the fuselage and
later parts of assembly of the model. Although these
jigs will not form part of the model and take to the air,
their careful construction will mean that the important
parts that do fly (the wings!) will align properly. It is
very important that the jigs are built accurately, so
take your time.
The cabane strut alignment jig
– This ensures that
the cabane struts are fitted properly so that the wings
fit properly too. It is important to note that there are
two jigs, which are the mirror image of each other i.e.
they are handed and both a left and a right hand jig
will be made.
1) Identify and remove the parts on the laser cut
sheets:
CAL and CAR (1 off each)
.
2) Referring to the cabane strut jig on the plan, cut
four pieces of 4.8mm wide strip (from sheet1) to
the lengths shown and set them aside.
3) Starting with part CAL to make the left hand jig,
glue the strips in position referring to the plan
and the laser etched marks on the part. Make
sure that everything stays nice and flat, pinning
it down if necessary.
4) Repeat with part CAR for the right hand jig.
The decalage jig
– These jigs set the angle between
the two wings correctly. There are two of these of
different sizes due to the different angle between the
top and bottom wings.
1) Identify and remove
all
of the parts on the laser
cut sheets:
WD1 (4 off)
.
2) Referring to the wing decalage jig outlines on the
plan cut four pieces of 4.8mm wide strip to the
lengths shown and set them aside (the two pieces
for each jig are the same length).
