Another player system question

Without referring to my notes I recall exposing about 1/2" of key-end  
and that the key-bed mortice was about 1/8" more.  The dags we used  
were metal 'C' shaped affairs (screwed to the keybed on the front,  
leading edge) and we morticed them into the keybed and notched the  
back-rail accordingly with room for the keyframe to shift.  Mind-you,  
this is all easier to do when the keybed is up on horses.

I remember on player crew from a manufacturer was attending and they  
said, "We used to just throw them away."  Mr. Zarate pointed out that  
that would void many manufacturer's warranties.  They now have  
experience with an alternative.

How many of you actually rely on the dags for bedding?  I wasn't  
taught that way.
