I know this is not the explicit question, re changing S&S spread, but if you check out the article I wrote a couple of months ago in the journal, and adhere to the concepts presented in the article, as long as the 110mm spread does not cause the end of the rep lever to hit the hammer rail, there is a good chance that the 110 will be fine. "Fine" means, that spread is about jack functionality. Prove the functionality as per the parameters in the article, and the 110 will be fine. Additionally S&S rails are low profile compared to other rails, so rep lever/hammer rail interference is afforded greater leeway with S&S rails.
When I was still rebuilding these frames, I had well regarded Steinway specialist rebuilders who agreed that in many cases 110mm on an S&S frame is fine, and allowed the jack functionality to perform as well as at 112mm, and actually requested the 110.
Regarding any leverage difference caused by the 2mm spread discrepency, moving the whip itself has such a tiny effect on leverage, compared to capstan placement, knuckle distance, and balance rail pivot location, that its practically un-measureable.

I use copper EMI shielding tape or Stained glass copper foil.

I see. When I do that I only shim the top of the flange as that's all you need to do to move the flange out. It's not necessary to shim out the entire flange, top and bottom.
I usually use thin brass stock (or even thin coat hanger wire) which rests nicely in the small indentation at the top of the rail.

Thin wooden applicator sticks also work

Hi David,
So I'lm looking for a material 2mm in thickness that will form itself to the steinway rail form when flange screws tightened against it. I want to shim out my wippen flanges to expand the spread.

I don't use the Masonite covered with felt either but make a brass piece which has a natural lubricity and then simply use a piece of felt (see photo). It produces a better string angle to the pin too.

FWIW, i have abandoned copying the Steinway masonite sheets. The main reason was because they are too thin, and I disliked the string going upwards to the coil. I have tried other materials, but what i have settled on is just hard maple, mostly because its widely available in my shop. I figured if its good enough for bridge caps. So i cut it to the desired shape, and then sand it to a wedge ( from zero to 1/4"). takes all of two minutes on my sander. Makes stringing much easier when the strings run parallel to the plate.

McMaster also has the vulcanized sheets. It looks like they are somewhat less hard than the phenolic and slightly lower tensile strength.

So I recieved my material from McMaster. Very nice shim material but the phenolic make it a bit stiff for my purpose. So it's some kind of dense paper I'm looking for. I'll keep looking...

So I'm pretty certain that what I'm looking for is paper based phenolic sheet. I just put in an order with mcmaster.com for three 24"x24"sheets of brown "Garolite XX" in 1/32",1/16", & 1/8" price without shipping is $38. Mcmaster.com is an excellant source for all kinds of materials and tools.

We've all seen this high density shim material in various places on older pianos. It's always brown in color. Sometimes seen under the stringing felt in the treble agraffee section. I've even seen balance rail punchings made out of it. Looking for a name of this material and a source.
