There is too much downbearing. The thought is to remove bridge <BR>> pins ... say five unisons at a time.... shave down the bridge top string <BR>> up again. This will necessitate plugging bridge pin holes and <BR>> redrilling as I need to come down probably 2-3 mm in places. <BR>> <BR>> The high spot of string deflection is the leading edge of the bridge. <BR>> My question is whether its best to leave the back edge at the height it <BR>> is and angle the bridge surface down more towards the leading edge... or <BR>> should I remove equally across the entire surface of the bridge ?... or <BR>> is there another way of going about this.<BR>> <BR>> I cant change anything about the plate height in this instance. I have <BR>> to accomplish this by altering the bridge. Back lengths are too long to <BR>> raise them enough by half rounds... and that would look wrong here anyways.<BR>> <BR>> Thanks for any input.<BR>> <BR>> <BR>> Cheers<BR>> RicB<BR>> <BR>> <BR><BR><br /><hr />Discover the new Windows Vista <a href='http://search.msn.com/results.aspx?q=windows+vista&mkt=en-US&form=QBRE' target='_new'>Learn more!</a></body>
