Got the thing running today. The synco-cog belt is smooth. Ran my 3hp air compressor. Whats great is each time I would start the compressor it would only drop about 4 volts and return extremely fast. Frequency would only drop to 56hz and then go back to 59.9 according to the Fluke 87 meter. And that is with the air compressor hot. The Coleman Powermate would drop almost 15 volts and frequency would bounce from mid 50s to mid 60s before stablizing from the govener and let out a puff of black smoke.
For one the big difference is the rotational mass is significantly higher with the HF head and pulleys. The powermate has very little mass to speak of.
Now I need to work on making it quieter. I don't think its much quieter than the Powermate which is obnoxious, just more cylinders barking in harmony. Not too shabby.
thx

Hi
check out these rex couplers web page we used these where I worked before retiring and they were much better than any other type. didn't have the alignment problems we had with the lovejoy or falk. The chain type had to be near perfect in alignment.

Jim, I'd like to show you a photo or two of an old military generator, that has a very impressive control panel. The wiring schematics were printed in 1953. It has a very small continental engine in it. ( Friend brought it out to me - major engine problems.) It appears to be 9K-10K output generator. Since it is military, it does have 120v,240v single phase and 3-phase capabilities. The control panel does have a volt meter, amp meter, cycle meter (50-70 cycles), and an hour meter. Of course there is a selector switch for various voltages and phases. Good luck with your project. Just thought you might be interested in seeing this one. Yugo

Doug,
I missed getting a hold of a Volkswagon diesel. Could have had it for $150.
With my experience from this project your two biggest challenges would be the speed governor and fabricating the coupler, either belt or direct drive.
The military engine I'm using has a mechanical governor very simular to this one at Surpluscenter.com.

The trick would be getting oil feed to it, but it works fantastic on mine. And for $29 bucks it would be worth trying.
thx
