Regarding the recent article by CentOre, titled: Need a Power Source? Got Water?: There is good info on the waterwheelplace.com web site for the do-it-yourselfer to calculate potential horsepower and watts from any given wheel configuration. Pa in Pennsylvania
James;
I won’t claim to be an expert on hydro power generation, but would advise against two non-durable materials mentioned: Instead of aluminum pipe for a shaft, get some steel pump shafting from an industrial metals supply or a well supply. Aluminum won’t hold up. Another is Teflon. While very slick, it will not last at all. I would suggest UHMW for the bearings if you are going to use plastic. Get in touch with a plastic supply to obtain some. It is not expensive, nor is the shafting very costly. – Michael H.
Dear Jim,
Yesterday’s discussion of floating boat mills reminded me of a very thorough article on boat mills and hanging mills in Low Tech Magazine. Anyone interested in this versatile technology should review it. Allow me to commend the online magazine also. With detailed articles on pedal-powered machines, human-powered cranes, ropeways, and other neglected technologies, it’s both fascinating and practical. Best wishes to all and thanks for your hard work. – W.T., M.D.
