<DIV><STRONG><EM> Hi Barb</EM></STRONG></DIV>
<DIV><STRONG><EM> Is till owe you a beer. Right?</EM></STRONG></DIV>
<DIV><STRONG><EM> Rebuilder or not we are often called to evaluate
problems not readily seen so it behooves us as Techs to be very careful when
rendering an opinion that may cause some one grief & expense if we miss
something this important.</EM></STRONG></DIV>
<DIV><STRONG><EM> Anyway there are quite a few ways to
determine this phenomenon. A very easy and visual way is to take a
six inch ruler, stand it on it's edge on the bridge between string patches &
see if it points a slope going up above the string on the speaking length
or below. Also pointing the long end on the back scale side will also
reveal an angle as well. Lowell bublle gauges are also useful in seeing
this as are the wooden bearing checking gauges I posted about a few months
back. I think I sent a picture.</EM></STRONG></DIV>

<DIV><FONT face=Arial size=2> Yes,well I tuned
& evaluated an 8 year old D today that was rented locally. It was voiced
with the usual Big bright concerto >hall sound. Nothing wrong with
that. Lots of power but not much sweetness. Plucking notes in the killer
octaves displayed more >sustain than the hammers were able to give in there
condition, so it lacked any tonal change over the dynamic range. But it had a
>fair voice.<BR>> Using a crown string revealed little
residual crown though the bass end & none in the top. However It had
plenty of bearing in >the top trebles. <U>Problem for me was that the
bridge slope was either flat or angling downhill on the speaking length side
of the >entire bridge so all the bearing force was applied basically
at the rear pins.</U> </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is this something you could actually see, did
your bearing gauge or level indicate it, or something else
altogether? I'm not into big deal rebuilding, but would like to be
able to recognize potential problems.</FONT></DIV>
