Plastic Elbows

[Ted Simmons]

I just returned from tuning a spinet which has plastic elbows.  I've been
replacing elbows one at a time for several years.  The customer decided to
have them replaced one at a time instead of all at once. There were 2 keys
down when I arrived and she knew what the problem was.  What she didn't
know was that the 2 keys were ones that I had put new elbows on in the
past.  The elbows had split where they click onto the center pin.  These
were the yellow type of elbows.  Does anyone know if the quality of modern
day click-on elbows is inferior depending on the manufacturer?  I've never
had this happen before but I've used mostly the clear plastic as
replacements. Any ideas?
