Steve, Rather than use a lighter wood have you considered removing some
wood from your existing box. You can draw a pattern on it, keeping strength
in mind, then cut out all the unnecessary wood with a jig saw.
Alternatively, use a circle cutter to cut large holes in the box, to create
a pleasing pattern and reduce the weight. You can buy a circle cutter at
the hardware store that will fit in a drill press or hand drill and cut up
to 6" circles. It is a very handy tool for a telescope maker to have.

A word of warning! Keep your fingers away. They stick out further than you
might think and they can flick the skin off your knuckles in the blink of
an eye.

Just a thought...............Malcolm
