There are over 50 turnbuckles on the Dr.1, mainly in the fuselage. To make rigging easier, drill
out each end of each turnbuckle with a 1/32” drill (.9 mm).

Cleaning laser cut parts
Laser cutting is a great process for making very accurate basswood and plywood parts that fit
together well. The downside is that it leaves a char or ash residue that can be easily spread by
touching and discolor your finish. Best is to wipe it off before removing parts from the sheet with
a paper
towel. If it won’t wipe off, use very fine (320) sandpaper. When removing a part from
the sheet do the same to the edges. Best to lay a paper towel on the work surface and draw the
part edge across it repeatedly, then lightly sand the edge. Be sure to throw away paper towels
and sandpaper often as the black residue will get on other parts. Make sure you keep your
hands clean or your fingers may track the char to the surface of the parts.
C.
Preparing stock wooden parts
Sand strips of wood with 220 or extra fine sandpaper prior to using.
D.
Glue
Glue wood parts with cyanoacrylate (super glue). To apply, put some drops on a paper pad
and use toothpicks to apply to the model. When the material on the pad gets stiff or hardens,
tear off top layer of pad and work from fresh sheet.
Best is to use epoxy for metal parts. Liquid Nails Metal Projects LN-203 or other 5 minute
epoxy is best. Mix small batches on paper with a toothpick and apply. LN-203 comes in dual
syringe that ensures the proper ratio.
NOTE:
BEFORE GLUING ANY METAL PARTS WASH AND ROUGHEN THE SURFACE
WITH A FILE OF FINE SANDPAPER.
E.
Part Number Scheme
All parts have two letters followed by a number. The first letter signifies the assembly on the
airplane:
E = Engine
F = Fuselage
L = Landing gear
T = Tail
W = Wings
This second letter signifies the manufacturing process used to make the part:
C = Cast metal
M = Metal bar or tube
O = Other miscellaneous parts
P = Photo etched metal
S = Wood strips
W = Wood (laser cut)
The one or two digit number is an identifier which is not necessarily continuous. For stock parts,
the Model Airways standard stock number is also given. This is of the form WPXXXX.
