[pianotech] The much maligned Use of Lyre

[Greg Newell]

Cy,

                The points that you’ve made are well stated and, in my
opinion, very accurate. The last paragraph really hits home to me. I see no
evidence that the lyre was ever designed to carry weight. It’s mounted in
the middle of a large flat panel with no support anywhere near it. Seems to
me that the designers would have put something substantial there if it was
designed to support as well as hang. 

 

Respectfully, 

 

Greg Newell

I heartily applaud piano movers who know what they're doing, use the right
tools, and do it well.

 

I think most of the problems I see are simple housekeeping errors: putting
the wrong bolts back in the leg holes, putting pedal rods in upside down,
losing the lyre braces (there's gotta be a warehouse full of 'em
somewhere!).

 

As far as lyre damage from tilting, isn't it possible that the effects
aren't noticed while the movers are still folding their blankets?  Couldn't
the joint be weakened or broken, and then work looser under play?  I sure
find lots of loose lyres; something causes it.

 

If the lyre needs fore-and-aft diagonal braces to resist the modest
horizontal vector of a foot pressing a pedal down, wouldn't it need a lot
more structure side-to-side if it were *designed* to be used as a fulcrum?
Look at the side-to-side bracing of the tail leg, for example....
