Subject: getting oil down prop shaft
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

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.
