regulation problems

[Mike Spalding]

Jeff,

Please clarify:  When the whites bottom out on the black FR punchings, 
have they dipped 3/8, or are they bottoming before reaching 3/8?  I 
don't understand which problem, or both, you are experiencing:
a)  Whites bottom out on black FR before reaching full dip,
       or
b)  Full 3/8 dip is not sufficient to get let-off and aftertouch.
 (I used 3/8" in the above problem statements, but as others have 
pointed out, you should probably be using  10mm, or .394", which will 
give you and additional .019" to play with)
