This is my Balsa-wood coaster, Archimedes - so named because of the 'conveyor belt' that I made to get the marbles to the top. The track is poster board as it was with all my roller coasters. Most sticks are 1/8"x1/8" balsa or bass wood, but the bending railing sticks are 1/4"x1/16". I got the clock motor from my little brother, Kevin, without which, this roller coaster would have never amounted to anything. Thanks Kev!
