Mike,
         I don't believe that I would lower the tension at all. (Fools go=20
where angels fear to tread and all that) :-) The tightening of the pressure=
=20
bar screws is not likely to be that great anyway. If you find yourself=20
making a major tightening I think that something is very amiss here.=20
perhaps a max turn of a half way around should be more than adequate. That=
=20
will raise the pitch to be sure but I don't think that you're in any=20
danger. You could always depress and hold the damper pedal, pluck a string=
=20
and turn the screw. Your ears will certainly tell you what's going on.=20
What's that old axium? Know What You Are Doing and Why You Are Doing It.=20
KWYADAWYADI. Re: #4 I don't think you have to worry about the depth of the=
=20
hole either.

Best,
Greg Newell
