![]() ![]() My husband also thought the swing arm rubbing against the wood was causing too much resistance, so he put Gorilla tape on the support arm. We made a knot in the bungee cord to make it tighter and have more force. Modification: This is where we got a little creative! First, the bungee cord appeared to have too much pull and wasn’t shooting our pumpkins very far. Step 9: Attach the cup so there is a little bit of the swing arm out, so you can pull it down! Step 8: Attach the bungee cord from the bottom eye hook to the top eye hook Place a washer and a nut on the end of the carriage bolt and tighten just enough to get the head of the bolt to sink into the wood. Insert the carriage bolt through one side of the catapult, through the throwing arm and then through the other side of the catapult. Step 7: Line up the 21-inch piece of wood (swing arm) in the center of the box already created. Step 6: Insert the additional eye hook 5 1/2″ from the top (opposite end of the carriage bolt) of the 21-inch piece of wood. This is for the 3/8″ carriage bolt to fit through. Step 5: Grab your 21-inch piece of wood and drill a 1/2″ hole 1″ from the end. This will be the support for the cross arm. Step 4: Take your remaining 10 1/2″ inch piece of wood and cut angles on either end. This should be attached to the rear of the uprights. Step 3: Screw the two upright 10 1/2″ pieces into place and then the 7-inch piece across the top of the two pieces you just attached. Holes for the carriage bolt should be drilled 2 5/8″ from the front of the catapult. Screw one of your big eye hooks into the end this will be the front of the catapult. Step 2: Take your two 18 inch pieces and your two 5 5/8 inch pieces and screw them together on the outside of the structure. So my husband was the adult in this situation For anyone that knows me well, I’m not just a kid at heart, I’m a little clumsy too. Otherwise, a table saw will need to be used by an adult only. It may be easier to go into a store such as Home Depot or Lowes and ask them to cut it for you. Step 1: Cut all wood according to the measurements above. Gorilla tape, to decrease the resistance of the bungee cord (Also a last minute addition!).(Not completely necessary, but it was a last minute addition made by my husband to increase the longevity of the cross arm.) 3/8″ x 8″ carriage bolt with one washer and a nut to fit.A bunch of small drywall screws at least 1 1/4 inch.A plastic cup or container to hold the mini pumpkin in. ![]() 1 piece of wood, 21 inches long (One edge should be cut on an angle.). ![]() ![]() The relief cut should start 4 1/8″ from the front of the catapult.)
