hello john,
your farm machine hub looks very strong.
it should be able to support a large vawt.
clean it up and paint it to look nice .
find a farm or auto parts place and get some new bearings for only a little money

i have seen the rahi profile before.
is it considered to be superior?

what is the total swept area of your device?.

remember automotive alternators are designed to turn at more than 1,000 rpm.
there are bettor ones to use .

don't give up when things get difficult.
good luck !

Thanks Dady, In my motorcycle days, the saying was: If it doesnt run, chrome it (-; Paint will come later. Bearings in hub are mint condition, after what, 25 years?
I dont know how to calculate swept area, its 1.1 metres high and 1.1 metres in diameter. As I plan to run the car alt off the base of the rim, I guess Ill have a 15:1 increase in rpm. Should be OK, I hope. If things work as I hope, Ill come back to better alternator design.

Cheers, john j
