Start with pine board that measures around 38 inches long, 2 inches wide, and 2 inches tall. Hold it in your hands similar to a rifle with one end pressed against your shoulder and your hands gripping the wood. Find a comfortable length and mark the wood where you want it cut. The longer your stock is, the more power you will achieve. However, it is not wise to go over 1 meter (3. 2 feet) so the PVC bow won’t shatter.

Use safety goggles to make sure you don’t get sawdust in your eyes. Saw in a well ventilated area.

Draw a rounded rectangle shape in the center of where you marked the trigger. This needs to be drawn on the top of the pine wood, not the side. The rectangle should be around 4 inches long, and 1 inch wide. Make sure the rectangle is drawn in the center of the wood where you have marked it.

Use a combination of all three tools to slowly remove the wood inside the rectangle until you have a rectangle shaped hole. Use sandpaper to smooth the area around the hole after you have finished.

Use a chisel or wood rasp to create a 1/8 inch groove near the front of the trigger hole. Sand the groove after it is cut.

Find and mark the center of the end of the wood, farthest from the string groove. Find and mark the center of the end of the rectangle hole, farthest from the string groove. Draw a straight line between the two marks. Use a drill, chisel, and hammer to carve a ¼ inch deep channel along the marked line. Sand the groove until completely smooth.

Cut the wood to be around 8 inches long. Use PVC glue or wood glue to attach it to the bottom of the stock, making sure it is centered. Leave the glue to dry for at least an hour.

Wait until the glue has dried completely before applying a sealer.

Make sure to measure and mark the length before cutting to ensure accuracy.

Insert a small wood screw on both ends of the PVC pipe. Attach the pulleys to the wood screws on either end of the pipe using wire ties.

Securely tie one end of the nylon string to the wood screw on the left side of the PVC pipe. Bring the string across to the pulley on the right end of the PVC pipe, and loop it in and around the pulley. Bring the sting back to the left side and loop the string in and around the pulley on the left. Finally, bring the string back to the right and tie it securely to the right wood screw. Do not pull the string tightly when you wrap around the pulleys or you will not be able to pull it back to fire the crossbow.

Pull on the string coming out of the pulleys. The PVC pipe should flex like a bow. If the pipe does not bend slightly like a bow would, pull the thread out and start again.

Use a wood rasp or chisel to carve out a rounded groove wide enough to fit the pipe on the end of the wood stock. The groove needs to be deep enough to fit the PVC pipe securely. Carve slowly while repetitively checking how the pipe fits. This will ensure you end up with the perfect fit. The pipe shouldn’t have room to move around.

Use duct tape to secure the PVC pipe to the stock by wrapping it around the pipe and the end of the wood stock. Only the firing string coming out of the pulleys should be on top of the wood. The other two strings should be on the bottom so they don’t interfere with the firing process.

Draw back the firing string and place it in the string notch on the rectangle hole. It should be able to stay notched and ready by itself. If the string will not stay notched, you need to make the groove deeper to hold the string.

Draw a rough L-shape on the wood. The small (horizontal) portion of the “L” shape should be slightly smaller than the box you carved in the stock. Cut the L-shape out of the wood with a saw. This L-shaped piece of wood will be the trigger. Sand it until it is smooth.

The hole should be big enough to fit the nail you are using to attach it to the stock.

Put L-shaped trigger in the rectangle hole with the groove facing upwards and the L pointing forward. Make sure it has space to move without hitting the back of the hole. Use a hammer to push a nail through the stock and hold the L-shaped trigger in place at the angle.

Use pine wood to cut a 20 centimetre (8 inch) length to be used as the handle. Sand it into the rough shape of a handle.

Use PVC or wood glue to attach the handle to the stock. Wait an hour for the glue to dry. When the glue is dry, you can use a hammer to drive a few nails into the handle to firmly secure it on the stock if you would like.

Secure foam around the end of the stock that is placed on your shoulder with duct tape.

You can either purchase bolts from a store or make your own out of dowels. To make your own bolts, cut a dowel to fit the size of the channel on your crossbow, and create a notch on the end of the dowel to hold the string.
