Dear Bob,

I am an Associate, and still a student, hoping to become an RPT.  I have
always been told that the glide bolts should be set properly so that the
keyframe is properly bedded, and that they should not be used to set key
height or adjust for key dip problems.

I have never experimented with this myself, and so I really don't know a
good reply to your query.  The response by Bob Davis sounded logical to me.
If there are other reasons for doing this, I would like to know.

Sincerely,


David A. Vanderhoofven
