Hey there. I have a website called Piano Price Point. If you're interested, I write a monthly blog about things relating to piano manufacturing. You can view it here: http://pianopricepoint.com/piano-blog/ This month I spoke to Andy Wilson from Mapes about how they make piano strings. I write about everything from hammer making to piano design going direct to the source if possible and learning from those who work in the field. Hope you enjoy!
