I live in Finland. I build a home wind turbine and I need some help from this forum.
I shall use an auto alternator/generator for to get the 12v – 14v that I need. An alternator has to spin (move around) very fast. For this I need a right angle gearbox speed changer. With a ratio of 1:10 – 1:20. Like in the picture that I attaché here.
Can be used one (very cheap  :) ).
Where can I find it here in Finland.
Thanks for your help.
