I'd like to make a steam-powered water pump and I've been studying Elmer's Vauxhall donkey pump but I think it's a little beyond my abilities/equipment at present, mostly because of the precision required in the valve area (a total travel of 2.5mm doesn't leave a lot of margin!)
It occured to me that I could re-arrange my last project to provide a 'direct drive' pump by putting the crank/valve rod on the opposite side of the cylinder to the piston rod/plunger something like this schematic...
Can anyone tell me if there is any inherent defect in such an idea before I waste time in a CAD program? Ta muchly!
