Edge 540/2.6m
Now that both the top and bottom halves of the cowl are
joined, it’s time to mount the complete assembly to the
fuselage. Align the cowl on the fuselage and check the fit.
Now is the time to make any small adjustments if
necessary. If all is OK, secure the cowl onto the fuselage
with masking tape.
The first bolt to fit is the top bolt. Finding centre here is
pretty simple, just use the seam line at the top of the
fuselage. Make a mark 10mm from the rear edge of the
cowl. All the bolts securing the cowl to the fuselage will be
10mm from the rear edge. From your centre mark measure
115mm, and make a mark. Do this on both sides of the
centre line.
Time to drill your holes with a 3mm drill bit. Don’t forget to
drill the hole where you have left the T-nut off when joining
the two halves. Place a 3mm cap head bolt in each hole
with an upside down T-nut attached from inside the
fuselage. You can now move further around the cowl
underneath the join line.
Measure 100mm from the side bolt and make a mark, then
a further mark 100mm below. Drill your holes with a 3mm
drill bit, and attach the 3mm cap head bolts with upside
down T-nut from inside the fuselage. Repeat this process
on the other side of the fuselage. Now it’s time to epoxy the
T-nuts in place, again don’t forget to light sand the area
where the T-nuts sit.
That’s it, the cowl is done!
