    How about wood, it cheap, needs no special mold, easy to replace if you don't shape it correctly and easy to waterproof.

    -- just a thought --

        How about sheet Lexan polycarbonate, which comes in different thicknesses. Much less brittle than plexiglas, sands and shapes/machines easily, and takes paint well. I made some bow planes and skegs that worked out well.

              I like to save a buck where I can, so I have used plexiglass for all of my control surfaces. The kind of plexiglass I am using (if there are different kinds) is not brittle at all, and even though I have not tried them out yet, they seem to be very durable.

              Just my two cents worth

                Jon,
                I guess I'm not the best driver, but I have run my subs in some tight places around docks and in test tanks that have interior metal beams to support the glass walls, and have broken quite a few "original equpment" control surfaces.
                Plexiglass is a brand name for acrylic. I have broken and repaired many acrylic products including an acrylic WTC, which fractured when I tried to insert an end cap.
                I still recommend polycarbonate, like Lexan, for these uses, in spite of the additional cost.

                  One problem I have with the translucent and transparent materials is even when painted they let an unscale-like bit of light through. What do you do about that? Just live with it?
