Pinblock Transplant in Steinway

I  suspect that the following  pictures may  show a  procedure that  some piano  technicians  will not  agree with at all. However, I have used these techniques in  many pianos over the last 25 years, and have found them to perform better
than  my  expectations. I  use a similar  procedure for upright  piano  pinblocks. The  transplant of a new pinblock area done in  this manner  results in a  piano that  has not been structurally modified. (For upright transplants, Click Here.)
Of Course, in a Piano that  does not  have the  pinblock  mortised  into  the  sides  of  the  piano, and  glued  to  the front stretcher, the block can be replaced and fitted in the normal manner. I feel that using the transplant method does no damage to the piano, and results in a very long lasting pinblock with tight pins!  Any comments are welcome!
