Greetings, Roger writes; > Using Roslau wire on a North American Piano designed for BS. SWG >will drop the overall string tension by 1000 to 1500lbs. Using Roslau wire of the same diameters? or using the Roslau wire of the same gauge number? 1000 to 1500 lbs seems like a lot for the change. (now, if you do go by gauge number, you will be .001" lighter on all notes +- some conversion differences. This I could see taking a lot of tension out). And wouldn't it be necessary to mention size when describing the "North American Piano", Since there is considerable difference in tension between a Baldwin SD-10 and Steinway S. Regards, Ed Foote
