OP OP Rubber314Chicken Golden Master Messages 5,574 Dec 13, 2006 #3 about 20 feet of rubber, 1/16"x3/16" and a great deal of wood.
OP OP Rubber314Chicken Golden Master Messages 5,574 Dec 13, 2006 #5 here- anybody who knows physics- how many pounds of thrust would be required to launch a 1.5 pound projectile 45 feet into the air?
