Plastic flanges

[Geoff Sykes]

Hi Steve --
 
I ran into a similar situation not that long ago, where both the elbows and
the damper flanges were made of plastic. The elbows all needed replacement,
obviously, as they were breaking left and right. The damper flanges are just
as fragile but because the stress they endure is far less than the elbows
they don't usually start breaking as early. However, as Phil mentions, if
you so much as breath on them they WILL crumble. Touching them enough to do
an alcohol/water treatment will likely be more punishment than they can
handle so be VERY careful in how you handle them.

Hey Now,
 
I have a question for the group. I have a spinet action in the garage for
elbow replacement. I was thinking of doing the alcohol/water treatment to
the flanges to size the bushings while I got it, just for the heck of it.
Upon closer inspection I find the damper flanges are plastic...hmmmm
probably the same plastic that the elbows are made of. What effect (if any)
would the alcohol/water have on these plastic flanges. The hammer and
whippen are normal wood flanges. This would be my target area, if the
solution got onto plastic what might happen?
 
Thanks in advance for any advise...
 
I know I should have left in a hurry, too late for that.
