A pelton turbine anybody with a welding machine can build (given the skills are in place)

IN this rar archive there is the Inventor 2012 components (.ipt) and assemble (.iam) of a 25 cups pelton rotor, plus some other formats like PDF 3 D, .IGS, .SAT, .WRL easily open-able with various programs.
The axis you need to customize it according to your local on the shelf bearings and sealing, the transmission to the generator can be direct or via gear reducer or belt, it depends on the generator you find, when designing the carcass please allow place for at least 2 nozzles that inject pressure water from the pen-stock that can be simply a 10 centimeters (or more) diameter pipe or sturdy hose that brings water from an altitude superior of at least 20 meters to the injection point level, better if more than 50 meters head, even if inclination is less than 90 degrees from horizontal and on a horizontal distance of 1 KM works just fine.
You can build this by having a foundry melt the cups in forms for you for cheap, cast iron is fine, better if steel, best is stainless steel, aluminum can be consumed too fast by debris. The shaft is water resistant steel turned and milled after you modify the drawings to fit your bearings and sealing.
The cups need little or no other work, but some sanding would do no harm, than they need to be machined on the arm so they fit ok in the shaft milled canals, than they can be welded with the appropriate material, be it stick welding or MIG.
I suggest the whole assemble to be balanced dynamically by an expert since it will turn pretty fast, and vibrations might ruin the carcass (not drawn)

Depending on the HEAD (vertical level difference between the collection input in the pipe and the level of the Pelton rotor) this rotor can power from 1 Kwh to 10 Kwh.
