Knowing the center reference line of a wood fuse is fairly
simple to set up during the construction process. For a glass/carbon/kevlar
fuse, it's also very easy if you follow this simple procedure:
- From the plan side view, determine the location of the reference
line vertically, on the rudder hinge line, and mark with a 0.1mm fine
tip pen.
- Cut a 1/16" balsa circle to the exact diameter of the nose
of the fuse.
- Punch a small pinhole through the center of the balsa disc
and thread a 2m length of sewing thread through it. Secure the
balsa disc on the fuse nose and tack glue
- Fish the thread through the hollow fuselage, to the tail, and secure
right on the reference mark made earlier on the rudder hinge line.
- Make the line snug and Voila! Instant fuse reference line.
Shine an intense light on each fuse side, at 90 degrees to the side,
and view and mark the line's shadow on the other side.
