Hello hello,

I made an attempt to sand the hammers on my studio upright for the first time and did a pretty OK job. However, I've noticed that only after light playing, there are grooves forming again. Is it normal for grooves to form quickly (within a couple of weeks) or is this an indication that the hammers are old? I don't think that the hammers have been replaced and the piano is over 50 years old.

Thanks for anybody's advice.

You didn't file enough felt off. The felt fuzz just filled the grooves and flattened out after playing a bit.

That makes sense to me! Didn't think about that. Thanks!

You should see string marks in the hammer surface soon after the hammers have been played 20-30 times. If you finish shaping the hammer with 220 it will shorten all the fibers that are sticking up. You don't want to leave the surface too rough.

You do not need to shape a used hammer to the point where you see no string mark at all. The bass hammers should have a definite mark remain because the strings are so large and as you move up to the small diameter strings the remaining marks should get small enough that the side of the string is unencumbered by the hammer felt.

+1.
You also know that you haven't removed too much of your, or your clients' valuable felt.
No less than A. J. Hipkins said that a controlled small amount of groove improves the tone.
