How to Make Wooden Rubber Band Guns

Mark the shape of a pistol on the side of the wood. Cut the pistol out with a coping saw or jigsaw, making the handle of the pistol a 1 1/2 inches wide. Hammer a headless nail into the front of the barrel, leaving 1/4 inch sticking out. Drill a shallow hole 1/8 inch deep into the back of the handle, in line with the nail at the front. Drill a hole slightly larger than the gauge of your wire in the handle of the pistol 1/4 inch down from first hole in the stock. It should be drilled from the back of the handle to the front. This is where the wire will be shaped into a trigger.

Push one end of the wire into the hole in the handle from the rear. With 1 inch protruding, bend it down to lay flat against the front edge of the handle. Feed another 1/2 inch through the hole from the rear. The 1-inch piece of wire is the trigger. Hammer the U-nail behind the handle to hold the wire in place. Don't hammer it down all the way, because the wire must be able to slide easily when the trigger is pulled. The U-nail should be inserted so as to leave a 1/4-inch space between the wire trigger and the handle of the gun.
Bend the wire up to the top of the handle with your pliers. Then bend it back toward the stock. Clip the wire so that the end of it fits into the 1/8-inch hole that is in line with the nail in the end of the barrel. This forms the firing-pin area.

Anchor a rubber band to the top edge of the trigger with a U-nail nailed beneath the barrel of the gun a couple of inches in front of the trigger. This will snap the trigger back in place after a rubber band is fired. This will also make the firing pin wire hold the rubber band that is loaded on top of the gun in place, ready to be fired. When the trigger is pulled the wire will move backward and release the rubber band from the 1/8-inch hole where it is pinned (the firing pin area).

Place extra rubber bands on the wire extending down between the firing pin area and the u-nail on the back of the handle. Then as you fire each band, you stretch another rubber band which is already hooked on the wire and snag it over the nail on end of the barrel. You can fire roughly 25 rubber bands a minute with fast reloading.
