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.
