Cowl Mounting
Slide the cowl into place and mark
the location of the landing gear on
the bottom. Using a dremel tool, cut
slots in the cowl to fit around the
landing gear. The cowl should over-
lap the fuselage 1/2”.
Cut 5 strips of heavy paper 3/4” wide
and tape in position on the fuselage
so one end is flush with the cowl
mount blocks. Make a mark over the
center of the cowl mount block.
Slide the cowl into position overlap-
ping the fuselage 1/2”. Use masking
tape to hold in place. Make sure the
stripes are aligned on each side. Let
the strips of paper be on the out side
of the cowl. Use a straight edge and
align the top of the cowl with the top
of the fuselage. Make sure stripes
are straight from fuselage to cowl
on each side. Check the left and right
alignment to make sure it is straight
with the center line of the fuselage.
When satisfied with the alignment,
use the mark on the strip of paper to
locate the mounting holes in the
cowl. Drill a 1/16” hole through the
paper, cowl, and into the mounting
block. Open the hole in the cowl up
to 9/64” and install a #6x1/2” sheet
metal screw with a #6 washer. Do
this in 5 places. Make sure firewall
is not touching the cowl on top.
