gear up the small ones

hi everyone, one of my small gen,s is a low output one, { I have trouble getting rid of this one, it does everything perfect but the output amperage is low } and oddly is almost perfect. these are the results of gearing it up 2/1. ok this is a modified alt, it has NO cogging at all. it uses a larger bearing on both ends, and is silent when running at any speed. what more could you ask for, maybe some amperage would be good. this one puts out 3.5amp in a storm, low output I know, but it does everything else vary good and has been on a pole for two years and works perfect except the output. so I thought I would try to gear it up, well it was a vary good idea. I added a lay shaft and two to one over drive gearing { #35 chain drive } turned the gen backwards on the mounts , and made a new hub mount to accept the standard hubs I use. I did change to a five blade from a three blade. back on the same pole and its only at 14 feet above the water on a lake at the end of the dock. yesterday we got the wind needed to see if it was worth the efforts. before any changes the highest amps seen by this little one was 3.65amp and you would of thought the house was going to move in that much wind. the new numbers are 8.99amp, WOW and the highest wind I seen on the wind speed meter was 22mph, not a really high wind. a huge change for such a simple modification . I watched the amp meter for 2 hours to see if it would hit a solid 9 amp and no go, it just wasn,t giving the 9 amp to me, no way no how. anyway the amps over doubled by a simple gearing to 2 / 1 or doubling the speed and adding 2 more blades. the start up was about the same but wasn,t able to see or record the speed that charging started at, the noise level was vary low but was a little noisier than before, vary minimal though, I don't think this would be a good mod for a cogging mill though, the start up would need such a high wind it wouldn't be any good without a big storm on the go. im already thinking why not 3 / 1 in the future this will be tried and we will see where this little one go,s from here, till then its food for thought. thanks for reading.
