Here is a picture of Chuck's modified Ross PSRU. Chuck
added a thrust bearing to take the load from the Ford C6 helical
sun gear and another oil feed line to lube it and the 
the sun gear itself as you can see here. An off the shelf
six pinion planet carrier is a possible future modification
if it proves necessary with a turbo three rotor.

He also experimented with a scraper on the ring gear to see if
he could get it to act as a pump. Indeterminate results
on this modification.

Notice the solid oil feed lines.
I mentioned this to Chuck and he has agreed to replace 
the solid oil feed lines with flex. The problem with solid feed
lines is they could resonate, fatique and crack. If that happens
all your engine oil is pumped overboard.
