<< Thanks Zy for your contribution.  I have noticed that among the spinet 
pianos 
 that have the plastic elbows, that the ones that had the weakest, most 
 brittle parts were the ones that had an uncontrolled Dampp-Chaser 
 dehumidifier rod.  I have often suspected that the heat from the rod 
 contributed to the degredation of the material but not being a chemist, I 
had 
 no way of proving or even researching that idea.
 
 Any ideas on this anyone?  I once replaced the elbows of a Betsy Ross Spinet 
 
 (one of my favorite little pianos) with the dehumidifier blazing away in 
 Winter where the elbows crumbled as easily as the Christmas candy that I was 
 offered while doing the job.  I needed no tools to remove the elbows or even 
 the remnants, I could break out the material with my fingers alone.

Blazing rods or not, the little buggers did not hold up over time. Once I 
replaced them on one for a local store, and my fellow techs loved to help 
break them by pound on the keys.  Some pianos including the Betsy Ross, have 
flanges of the same material. The new space age plastice seems to be a lot 
better, but I have replace several sets with wood as well.  Either way, they 
should outlast you and me.
