   Hi ROn

  What's the decimal equivalent of 6.8mm.  I find that a letter f .257 is a
bit too tight for the block you are describing.  .261 seems better in CA
climate. I hate tight tuning blocks. A tight block in a piano makes for it
to be more likely to be more out of tune more of it's life. JMHO 

  You Know?
