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.
