Greetings Del, Do you think it would be worth while increasing the pressure from bass to treble on ther cold press process, to try to get more brilliance in the top end, yet still keep a warm but singing quality in the centre section? I'm sure some one must have some data on this. Tapered pressure to correspond to the taper of the hammers, or am I nut's? With modern torque wrenches, I think a variable press would be easy to design. I think???????????????? Regards Roger > 3) Inconsistent press pressures. This is the most likely candidate. On >hand operated presses, the pressure depends on the torque applied to the screws. >What condition are they in? When were they last lubricated? How much sleep did >the press operator get last night? Etc. Roger Jolly Balwin Yamaha Piano Centres. Saskatoon/Regina. Canada.
