Wurlitzer Flanges

[Frank Emerson]

Makes sense, Captain Joe!

Sounds like silicone is not the problem, except to the extent that it enables the manufacturer to do sloppy pinning.  If so, who cares if the silicone creep back into a new bush, or remains in the old bushing, as long as the pinning is done properly.

You have to take what I say with a grain of salt.  I haven't serviced pianos in the field much for the past 20 years.  I spend my time building pianos in cyber space, for someone else to built with real materials, and someone else, again, to service in the real world.

I really have to disagree on this one. Think about it.....Why did Wurlitzer use the Sillycone in the first place? Answer because their pinning consisted of poor techniques..i.e. jamming an oversized pin into a flange bushing that was not reamed to the proper size. It eliminated a step in the pinning process. They saved money on Labor! Their answer was Silicone. As for the silicone "creeping", where is it going to "Creep"? Onto the hammer rail, most likely. Then where? My answer: No place of any consideration. Some seem to think this is the Invasion of The Blob or sumpin'...Sheesh! It is not that big a deal. There are a plethora of Wurlys out there, that have had this done to them and they work as well as any other PSO, IMO. My experience has been that proper re-pinning takes care of the initial problem...permanently.
