     Okay, okay - I'll concede the point. 

     The original poster asked about *his* situation. I stand by my advice to 
'not pin' since he's dealing with 4130 which will be a bear to drill. It's 
more of a practical consideration to me. I guess with the Yaesu 
'prone-to-break' clamps, they're just ensuring that the mast won't slip 
inside the clamps.
