[CAUT] Teflon Bushings

[Delwin D Fandrich]

So, please explain all those Steinway actions with Teflon bushings that,
once the pins and bushings were properly installed and mated, have gone on
working flawlessly for some three decades now. 

 

I understand about the hole in the wood and occasionally it could be a
problem. But not nearly as often as was claimed by some. It was also a
problem that could easily be fixed.

Del,

 

    With all due respect, give credit to Steinway. Basically the quote

from the WNG site on what went wrong. Along with " a hole in wood

is circular only at the EMC which it is drilled at."   Therefore,

I agree for contact stiffness the hard bushing for the shank flange

makes all the sense , anywhere else in the action, just get rid of it

or make teflon beaded necklaces.
