true why does the veneer glued on the sides of a broken key affect such a
lasting repair?<br><br>

am toying with trying to put a very thin coat of epoxy on either side of
the key about two inches on either side of the button. This may
give me the stiffness they need. <br>
<br>
<br>
From a structural standpoint all of your stiffness comes from the upper
and lower fibers of the key. Think of the key as an I-beam. The load of
the I-beam is carried by the upper and lower flanges. The web in the
middle carries next to nothing, it only connects the flanges. <br>
<br>
So adding stiffness to the sides will not accomplish much. It needs to be
added primarily to the portion under tension, that would be the top of
the key. Most of your deflection will come from the wood under tension,
not the part under compression. And the weakest part of the key is the
balance rail hole. So the greatest payback is to add your stiffness to
the button and the connection of the button to the key. <br>
<br>
Super glue would penetrate the wood and the glue joint of the button.
Keep it away from the bushing cloth, obviously. <br>
