An automatic soda can crusher can be built at home using readily available supplies from most hardware stores, including PVC piping, PVC cement, a 3/4-inch steel pipe, a washing machine hose and some power tools. Lumber, screws and compressed air is also required.Continue Reading
With a 3/4-inch drill bit, create a hole in the center of a 2-inch PVC end cap. Glue the end cap onto a 2-inch PVC pipe.
Remove the clamp from a washing machine drain hose adapter, and attach the rubber fitting over one end of the steel pipe, wide end down. Wrap with electrical tape. Insert a 3/4-inch steel pipe into the PVC pipe and out of the drilled hole in the end cap. Cut the steel pipe so that just 6 inches is visible outside the PVC pipe. Glue a 3/4-inch end cap to the other end of the PVC pipe.
Glue a 1 1/2-inch PVC coupler to the bottom of the PVC pipe. Drill through the pipe and coupler and attach a 3/8 by 3-inch nipple. Measure the length of the piston when extended, and add 6 inches. Cut 3 lengths of lumbar to this size.
Arrange the lumber in a "U" shape (two boards standing up with the third on top). Screw together. Cover one of the open sides with additional wood. Drill a hole in the center of one side to feed the air hose. Attach the piston crusher to the box to complete the project. Video tutorials are available at Hackaday.com.Learn more about Appliances
