I thought this had been explained pretty thoroughly, and repeatedly. Seemed to me to be a wash of several reasonings by several people... but ok perhaps I misread... shore nuf wouldnt be the foist time :) But if massaging then is supposed to accomplish this... how are we to ascertain when the tensions are really equal ?? If we were to go by sound then we would have to know in advance just exactly what pitch these segments were supposed to sound at. And there seemed to be a lot of reasonable argumentation made as to why this would not be possible. You could get ball park results perhaps at best ?? And if we dont go by sound ?? we dont carry string tension measuring devices around with us do we ?? :) But like I say... I have considered and dealt with the front duplex, but not the rear. And in "tuning" the front duplex I mean determining the desired placement of the counterbearing. > > > Ron N -- Richard Brekne RPT, N.P.T.F. Bergen, Norway mailto:rbrekne@broadpark.no
