several years ago I bought off of ebay a couple hundred 4x36x1/8 sheets of balsa wood for cheap. wow, was I in heaven-- until I got it. the sheets would curl up when taken out of the box. i realized that it had been made by rotary cutting the logs, the same way that plywood veneer is made. several years earlier i acquired a box (50 2x4 sheets) of 1/4" light grade tessellated (end grain) balsa wood. both items were put in the attic waiting for me to come up with a use.
today i took one of the 2x4 end grain sheets, the same stuff they are using for those windmill blades, and cut out a 4x36 piece that i sandwiched in between 2 of the 1/8" sheets using a light coat of titebond glue and placed it in the press. i actually did 4. what came out of the press three hours later were four, light weight, perfectly flat, stiff, and i think, strong profile fuselage blanks. ringmaster. thanks, joe
