You just get the R8 spindle, not R8 and R4.
Shop-built 4 axis CNC Sherline mill with A2ZCNC extended XY and CNC Sherline lathe.
4 axis CNC Grizzly G0704 - based on Hoss' plans Manual Sherline 4400 and LMS 3540 lathes
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.
