Grandsons did some of the welding, lots of technique for them to learn yet.

I'll let them drag the 200 ft of sch 80 surplus pvc conduit thru the woods for the penstock, will try to remember to take pic of that when we install

the old chevy 2.8L flywheel gear will drive a starter pinion and the generator at about 4000 RPM.

I forget how to insert an image without having it on the web ? Attachment 6981
From what I've built in the past , I'd go with direct drive 3 phase gen instead of geared , you'll loose valuable energy through the gears at that sort of step up could be 20% . Noise and wear will also be an issue long term.

For a cheap 3 phase gen look into Fisher n Paykel washing machine motors as a gen, 3 phase at 450v AC at 1000 rpm is no problem for low loss long runs .
