 I sincerely am thankful all that had come to help with the question of 
tuning pins me for the Bechstein. Not wise person who had attendance of as 
many experienced colleagues soon that not even they know me.  I find that it 
can have difficulty to express me because of the language (my message I 
translate of google and repair the terms technician).  To really substitute 
pinblock could not be the solution a time that it is very good and the 
problem if the iron plate finds in the length of tuning pins therefore has 
7mm and it does not have bushings.   To install bushings in the iron plate 
will not be possible because the diameter of the punctures is of only 8mm 
and at the beginning of the medium the space well is pressed to become a 
bigger puncture .I thought and I took the following decision not usual:  If 
necessary that it has greater length of contact of tuning pins with pinblock 
I go to roll only 2 aneis of ropes in tunings pins and driving 3mm of height 
in relation to the iron plate. They will be only with 20mm of total height. 
I will on average gain 7mm in the sharps and 5mm in the serious ones of 
contact with pinblock.  To compensate the tension, I will increase in 2mm 
coupon stubs of I lean soon of strings above of agraffes (not to force the 
same ones).  A piano technician that to look at the piano it goes to scare 
itself when seeing, but if to know of the problem will approve the solution. 
 It will be that somebody disagrees?  Francisco Motta Techniciam Piano in
