![]() ![]() ![]() Someone (Daryl Adams) sent me this picture recently If you have a low-melt glue gun & lots of styrofoam cups it's possible to make a screw pump by cutting the bottoms off lots of cups at the same shallow angle (use one as a pattern) then glue them all together with a slight rotational offset on each one so they don't just go round in a circle. It is uncannily similar to the very first model archimedean screw I made, although his one works. This is a design by Jeff Bindon available from him as a kit: My pump used metal end fittings and plumber block bearings. ![]() The pump is turned by means of a solid post along the middle this must be a good fit in the centre space frame to prevent stress concentration. ![]() They have to be held in this form while the pump is completed. After glueing the disks together they should be held in a jig while the center is inserted and the outer cover formed.Īlthough the disks are glued together flat, they have to be stretched in order to form the archimedean screw. This shows how to glue two plywood disks together more disks, longer pump. This animation shows how water is carried up by the pump Top in the middle, so this bit has to be made stronger than the rest. Water pump made out of thin plywood and resourcinolĬhristmas decoration, the center is made of a wooden space frame covered with Plywood archimedean screw water pump plywood archimedean screw water pump ![]()
