Comet
Sailplane Project
I finished up the front end of the cowl today.
The picture below shows the first layer of 3/16" balsa sheet being
glued onto the front face of the cowl. Notice the lateral grain
direction. To apply pressure to glue joint, I laid a maple board on the
back of the cowl and placed a heavy iron vise on top of the board.

3/16" balsa sheet being glued onto the front face of the cowl.
I trued up the inside of the three cowl rings
and sanded the outside to contour as shown below. More finish sanding will
be required, but this is all I am going to do for now.
This picture shows the cowl installed on the
fuselage along with an APC prop. There is a full 1/8" clearance between
the prop and the front face of the cowl.
This picture shows a close up of the front of
the cowl.
The cowl design and development is in good
shape so this will conclude the work on the cowl for the present time. I
will now get back to covering the rudder and stab so I can eventually do a
weight and balance to determine where to locate the pylon primary
