[CAUT] new front pins

[Mike Morvan]

Fred,
    What circumstance has you replacing a front rail pin with a smaller 
"shank" or core diameter than the original? Usually it is the other way 
around, requiring the technician to enlarge the hole slightly for 
replacement pins.  Are you trying to put in the new M&H anodized pins? If 
that's the case, I spoke with Bruce Clark at the Mid-Atlantic Conference and 
he stated that they would be providing nylon bushings to tap into the 
keyframe and then the technician would tap the pins into an undersize hole 
in the nylon for a press fit.   Mike
