Hi Paul, thanks for the info.
That much I can do. What I'm trying to figure out for the missing string is the position and length of the winding, distance between winding and hitch pin as well as agraffe. I'm assuming the length of the winding will be the same as that of the other string, however it's placement in relation to the lengthwise center point of the core between termination points will be offset relative to the bridge and agraffe.
For example, if I copy the specs of the other string, it's counterpart replacement's winding will contact the bridge pins. I could peel back the winding to solve this, but I'm thinking that will cause a mismatch and sound terrible for numerous reasons.
I hope that's a clear enough description of what I'm after. I definitely need to study scale design.

Hi Ruben:
You'll need a micrometer to measure the overall diameter of the other string, plus the diameter of the core. You'll have to measure the length of the string from the agraffe to the hitch pin, and the length of the speaking section from agraffe to the bridge pin. Removing the damper head will make it easier to do this. It is possible that the string winder has the measurements for the string if you have the Make and Model, but even that might not be correct.
A Universal string is another option if it's not a high-end piano. I know, they often don't sound good or match, but sometimes they do a pretty good job. Even if they don't like it, and you still have to have a custom string wound, it will at least get it up and running while you wait.
