Tracey is probably the best one to answer this, but = many may=20 know the
answer.

In the RD-1x, the oil flows down the prop = shaft,=20 out the end, and then
through the sun an planet gears.  How = does the=20 oil get in the shaft to
begin with?  The thing is spinning at = 2500=20 RPM.  My mental view is of
the shaft doing everthing in its = power to=20 throw the oil OUT.

Work was begun to drill the prop shaft I = have, but=20 it was never
finished.  I'm wondering if completing it will = be worth=20 the trouble.
