So I finally threw in the towel with my mickey mouse "commercial" puller.
I finished my custom puller last night about 12:30 am and had to slap it on there and try it. After about three good turns on the bolt, the flywheel came loose and then slid right off. The whole process took less than three minutes. If you want/need to build one, here's how:

Here's pics of the puller:
First an overview. The two "C" shaped plates are installed behind the flywheel. The two plates bolt together with (4) 1/4" capscrews. The plate with the big hole is closest to the crankcase and just fits over the bearing housing. The plate with the smaller hole fits nicely over the 2" crankshaft and does the actuall pulling on the hub of the flywheel. When the two plates are bolted together around the crankshaft, there are three holes available for the 3/8" allthread to connect to the 1/2" puller plate. The puller plate is really (2) 1/4" disks welded together (because that's what I had laying around handy. The central bolt is 5/8" allthread with a nut welded to the plate. The nut goes toward the crankshaft.
Here's the hindmost plate that fits over the bearing housing closest to the engine:
Here's the second plate that bolts to the first plate and fits over the crank and actually pulls on the hub:
And here's the puller plate, self expanatory:
Sorry for the sloppy weld, cuts, ect. I was in a hurry. Didn't chip the slag off, etc. etc. I know you've been there too...
Wooo Hooo, I can get on with the overhaul now.
Hope that helps somebody on down the road.
Finest regards,
