Pinning on new flanges:a proposed experiment

[Richard Brekne]

The plot thickens... grin...

and this is still just on the reactive side of the question, and still 
only dealing with the friction / control issue in the greater question 
of just how tight to pin the centers...

Ya gots to love it.

Thanks Isaac.  I havent had a chance to read carefully through this 
whole article yet.

Cheers
