[pianotech] Steinway Teflon?

[reggaepass at aol.com]

One of the things I'm looking to see is how Ron Losby's integration of the various parts, techniques and production processes between NY and Hamburg fairs in practice.  I think both ends of the equation have something to learn/gain from each other.

Greetings Horace,

Please elaborate.

Hi,

Ed is right; the phase out started in the '82/'83 production year with D's and B's; by '84 just about everything that had had old style teflon was through the line...it's not like they removed parts from what was already in the line and/or in supply.  What's a little deceptive is that the use of teflon has continued with teflon-impregnated felt bushings even while the Renner/Hamburg parts were also in use off and on (mostly from '84 through '87).  And, as we all know (from endless repetition) the geometries weren't exactly interchangeable.

In fairness, though, a great deal of time and resources went into working out what combination of machining, felt density, type of solution, etc has gone into the impregnated bushings over the years.  While the earlier stuff was pretty nasty, and there is still room for improvement, the later production has been reasonably stable.

One of the things I'm looking to see is how Ron Losby's integration of the various parts, techniques and production processes between NY and Hamburg fairs in practice.  I think both ends of the equation have something to learn/gain from each other.

Best.

Horace

Hey Guys/Gals,
When did Steinway cease the Teflon Actions in production?

Mostly by 1984.  There were a number of pianos with cloth shanks and teflon whippens sent out during this year or the one before.
