Hi experts out there... Just a quick question I'm hoping for a few hints on. Given a soundboard that deflects from 4mm of crown to 1 mm of crown with 250 lbs of presure spread over its surface roughly evenly.... what kind of downbearing pressure should I be looking at achieving. Said another way.... what kind of string tension should I be looking for. The scale I am working with is a very low tension scale with plain wire breaking %'s around 35 %. with modern wire used as a base for figureing. I'm thinking that an increase to 45 % should be perhaps a minimum. The scale needs to remain quite low tension because of structual concerns.. Thoughts ? Cheers RicB
