[CAUT] Thumping Baldwin SF

[Porritt, David]

Ed:

You know, for some reason I always thought the "front rail glide" was a good idea.  Knabe did that on some pianos early in the last century.  I've adjusted them and had good results.  There's something that bothers me about "destructive" ways to adjust things.  Removing wood on the front rail that can never be put back on to adjust the fit seems odd though I'm aware that it has been "traditional" forever.  I just prefer systems that can be actually adjusted.  OK, it's just one of many psychological flaws.

I heard Cliff Gears speak scornfully of the Baldwin "front rail glide" 
system. He said "When you see this, yank 'em out, glue a strip of wood to 
the bottom edge of the key frame and seat it right."

Good morning Joe!

But if it's bedded properly why would it knock? Isn't that the definition of 
a bedded frame; no knock? And how could bushing cloth possibly NOT wear out 
there, and rather quickly? I learn new things daily on this list, and Jon is 
one of the best. It's just something I haven't seen nor thought of. And how 
do you adhere it? Jon?

Regards,
Jim

Hi Jim,
If you tap the base where the (key bed) action lies sometimes that area will
ring like a drum.

I've had luck with Crescendo punching.

Jon, you covered the glides?? Were they knocking or something? (I'm
certainly not questioning you're abilities, but this sounds a little weird.
Explain?)

Jim Busby

I had this thumping noise on an L from the '70's. Replacing the impacted
front rail punchings did not quiet it enough for the player.

I ended up covering the bearing areas on the bottom of the key frame
and glides with bushing cloth.
