Margie Warnke told me the same thing about my prop. No coincidence - Margie 
and Clark were once married and learned the art of prop carving from her 
father Bernie.

My problem - appears I have too much prop - would like to get a little more 
RPM out of it. But I'm a little hesitant to start whittling on it for fear 
of screwing it up. Margie's vanished off the face of the earth and Clark has 
retired.

Guess I'll just have to trade up to an RD-1C and a new Catto prop.
