No magic is involved.  Same way as oil gets into the Mazda (or most any engine) crankshaft.  The rear prop shaft bearing is a large pressure fed bearing with groove in middle that matches up with a hole in the shaft.

Tracey is probably the best one to answer this, but many may know the
answer.

In the RD-1x, the oil flows down the prop shaft, out the end, and then
through the sun an planet gears.  How does the oil get in the shaft to
begin with?  The thing is spinning at 2500 RPM.  My mental view is of
the shaft doing everthing in its power to throw the oil OUT.

Work was begun to drill the prop shaft I have, but it was never
finished.  I'm wondering if completing it will be worth the trouble.
