I thought I might be able to determine the tuning pin head taper directly from a pin, but as it turned out, I was not able to do this to the accuracy I was hoping for. I have since talked to the German producer of the Biene tuning pins I carry. He said that supply houses approach him from time to time for tuning pin specs to use for tuning hammer production. According to him, there is no standard for the taper, but this is not to say that all tuning pins are different. There is also the question of quality control. My feeling is that with cheaper brands of tuning pins, there is more variation of virtually all critical dimensions of the pins. I have requested a sheet of technical information on the Biene tuning pins by mail. When I have received it, I will report back on the angle of the square taper and any other interesting information Jurgen Goering Piano Forte Supply (250) 754-2440 info at pianofortesupply.com http://www.pianofortesupply.com -------------- next part -------------- A non-text attachment was scrubbed...
