Glue a 1-5/8 long 5/32 brass tube into the top of
the oiler block.
Rudder
The rudder mounts to a brass tube in the hull,
and is supported on the bottom by the keel
shoe.
It is very important that you drill the hole for the
rudder correctly.
If you do not, the rudder will not line up with its
lower support.
Glue the 2 small squares together.
Glue these just at their edges as shown.
This leaves a little “notch” that we can use as a
drill guide.
Sand the tops of the bulkheads and glue the
radio tray in place.
When cured, use the drill square you just made
and drill a 5/32 hole thru the hull bottom.
Drill down through the hole in the radio tray.
Use your square to be sure that the bit is square
in 2 planes.
Take your time and make sure that you are
drilling straight.
Roughen the 5/32x1-5/8 brass tube and slip it in
place.
Leave a tiny bit of brass sticking through the
bottom. About 1/16 or less is good.
