[pianotech] Fwd: Erwins key dip gauge

[Richard Brekne]

Hi Al

Pretty sure I ran into this in some journal article years ago... I 
suppose I'll have to dig it out myself and post a year and month.  Made 
perfect sense as I remember... but I cant visualize it now either.

Cheers

    Hi Ric

    I have not done that, and I can't imagine how it would work. I'd be
    interested to know how it could be done.
