If any one is interested, my wood turtle deck finally came out at about 9
lbs, which is a little bit heavier than I was hoping for. Just for the record,
if I were doing another one, I would use 1.5/2.0 mm Hoop pine for the ply
frames and skin, ( hoop pine seems to be very springy stuff, but it is a
certified engineering material ), omit one 5/8 thick wood rollover frame
instead of having two, fit the skin as three separate peices, instead of two,
for a total cost of about $70, and probably about 7 pounds. The equivalent foam
version would cost about $100 for foam sheet, foam block would be about
$400-$500 if not more if used, $40 dollars for resin and about $150 for glass
and peel ply, so about $300 or so. If cost were not critical, then Gary Morgans
core mat decks would be the way to go.
