Looking thru my many whipper snipper engines the other day and came up with an idea to use a Ryobi eng as the basis for a small wind turbine. I pulled the little ryobi apart and found some of its design suited a small turbine. The rear end (where the reed valve sits) has 4 bolt holes that you can attach a tail to. The cylinder head flange will support a yaw bearing assembly. The magneto plate 4 bolts will support a plate with your coils on it. The shaft itself already has 2 ball bearings and I simply removed the counterweight from the end inside the crank area. Another plate on the shaft with some magnets and the prop in front and you're in business. I've just started to build one so I will post some photos shortly.Edited by waggawind 2009-04-17

I think this is a clever idea. These motors have good bearings, with seals on the outside. The only problem you may have is with some motors the bearings are open on the inside of the crank case, they reply on the two stroke oil for lubrication. You may have to fill the case with some oil, just enough for the crank to splash around. The splash will lubricate everything.

Thanks for the reply Glenn. I will lube the bearing and crank area as I will seal it up. The plan is to make an axial flux alternator and mount it to the 4 mounting holes/shaft. I have included some photos of what I have done so far.You can see the cylinder flange for the yaw bearing mount. On the photo that shows the inside of the crankshaft, you can see the counterweights have been removed .
