Paul, thanks again for all the info you have passed onto me so far...I am
still missing two pieces of information to mill up my variable pitch hub as
per you drawings...These are:  the holes dimentions and spacing to attach
the pitch change motor assy to the hub, and I would like to know, how do
you actually attach the pitch change yoke to the blades???  Thanks for this
info...

There is a square flange on the motor with, as I recall, 6-32 screw
holes. When you get the Pitman or Globe catalog for those
motors the flange details will be in those. 

Been thinking about that however. IVO uses an aluminum
sleave with a flange to support the pitch change motor. 

That's probably not 
a bad idea as those four 6-32's screws seem to be a wee bit marginal 
slinging that motor around at 2800 RPM. Any slight mis-alignment and
it could wip itself off there.

There are two .375 diameter pins pressed into the 4340 stubs
top and bottom. The yoke is slipped over the pins and is held in place
by
assembling the cover down over the stubs and yoke. 
There is no other connection. The yoke acts to keep the stubs properly 
located. The ends of the pins clear the opposite stub. You will 
need a little grease in there.

Please take some pictures as you machine those parts and send
me copies.
