[pianotech] hex size

[David Stocker]

The hex bolts go in to the back of the piano, through brackets located where hinges usually go. You have to pull the piano out from the wall, get the bolts out, then lift the lid out of the way. It is probably the most secure school piano. Save from even the uninitiated tuner.

I had one in a home I tuned regularly. I left the bolts finger tight only.

Yikes!  Doesn't that scratch?

  What’s the hex size to get into an Everett piano?  Thought I had the right one in bag, and it turned out to be a Kawai leg hex.

   

  Also  the brand “Howard”, produced by Kawai.  Does one search Kawai numbers, or Baldwin numbers, or Acrosonic numbers to learn the age of such a thing.? 

   

  Thanks much
