[B]Came across these ads on E-Bay for mill spindles- looks like a good deal for a DIY milling machine project.

You just get the R8 spindle, not R8 and R4.
CNC hobbyist since 2003.
Current CNC hardware: Sherline/A2ZCNC extended, 4 axis X/Y mill and Sherline lathe
What size machine you planning on?
Have a look at Littlemachineshop.com and see what they have too.
They have ones from the Sieg SX2 & SX3
The SX2 one may be shorter than the one you looked at (unsure). Both would be able to use 35 & 30mm inner diameter AC bearings too.
They do have drawings of dimensions somewhere.
