ConclusionĪ catapult may be a bit difficult to design and construct but no doubt this is a good family project that you can do in a weekend. Add a payload to your cup, wind your broomstick cranks, release the catch and fire to launch the object to the air. Turn the handles to create torsion in the rope. Place an object in the basket to arm your catapult and apply torsion. Let the arms restfully back in the launching position this way you can tell where is the best place to install your catch. As you twist your handles, the torsion of the rope will make the throwing arm ascend until its tension holds it near the cross brace. Knot the end of the cord to the side of the arm. Loop the rope around the second handle, and then take it back through the frame to the first handle. Lace about 20′ of rope around a broomstick handle, then take it this to the hole in the right side of the base, through the hole drilled in the arm of the catapult, to the other side of the base and back to the second broomstick handle. Assemble everything using long screws to ensure your frame is sturdy. Do this in the same way you constructed the right side.Ĭonnect the left and right sides with the base of the triangle and base of the 36″ 2×4 forming the bottom of the base. Next, construct the left side of the base and fasten the other triangular plywood piece. This creates one base leg of the catapult. The diagonal will be approximately spanning the distance in between the two ends of each 2×4 plank. The base will be parallel with the 36″ plank. The 18″ side of the plywood will be vertical to the 36″ plank. Screw these planks of wood in place.Ĭonstruct the plywood triangle. Place your 18″ 2×4 at a right angle to the 36″ piece at 15″ from the end of the 36″ piece.
