Of course I would have liked for it to have worked perfect the first time, but such is life as they say. I still have to check to see if it is a chain slipping somewhere, or the gear hub. I suppose if it's the gear hub, I'll end up putting an S-A 3x9 in it, but that means having it laced in a rim which means more money and longer before I get it on the road. The good news is that while it was running right, it was incredible. Keep on keepin' on as they say.

I am sure it is disappointing for it to not be 100% perfect on the first try. Rest assured that companies spent 1000's of $$ on similar engineered designs which turn out to be totally useless because they can't even find a bearing which will take the load they have miscalculated to exist.
Did you try the suggestion of using a freezer and heated components for assemble. This is very good, valid advice. I have used it on everything from PS pumps to ring gears on flywheels. No beating the bearings to death is needed.
Don't expect a geared hub be happy with 10X it's intended input.
Maybe try a single speed as proof of concept and go from there?
