Got it made, that polar/vector syntax works nice, thank you very much for the example. Everything fits except the motor bolts, I bored the holes big enough I could grab a 5x.8 tap in its hat and run it in by hand. Turns out my 1/8" tool was actually 3.45mm. Grrrrrr. All I need to complete that is to dis it from the gearbox one more time and turn off about 1.5" of surplus flange. And make a shaft adapter. But I'm still waiting on a set of reamers. But I just checked the order and earlest arrival is July 22, another 11 or more days I'm sitting on my butt. Sigh...
