Yes, these governors were built to last if lubed religiously- too bad most of these were not maintained and ultimately added to the historical junkpile of forgotten works of engineered art. I can understand why Jacobs later upgraded them to the blade-actuated governor type- less moving parts, all stainless steel, no real maintenance, and obviously more consumer appropriate. I mean, who works on anything these days? I can see why there are only a handful of hold-outs who still rebuild these extinct wind generators............. I'm still debating which way to go, flyball or blade-actuated. But one thing is certain- a Jacobs wind machine with either type governor is probably the only one ever made to handle unruly wind signatures (uneven gusts coming from different directions) because of its big mass and very stable inertia, and all done in a very quiet way. It refuses to get tossed around!
