Just keep combing those needles through your hair. Better if you don't wash your hair.

I did an experiment with lanolin this week. Monday I tried a solution of a good bit of lanolin dissolved in lacquer thinner on the shoulders of the original hammers in a 1963 Steinway, hammers I had considered "unvoiceable" because the needles wouldn't penetrate, due to too much friction. While the solution was wet, needle penetration was quite a bit better. A bit squeaky at the bottom (that last couple mm of penetration) and with a good bit of resistance to pulling out, but much better than dry. So I soaked all the shoulders of all the hammers. Today, I tried some sample hammers, and it was like voicing a normal hammer. Needles went in and pulled out with relative ease. The lanolin solution had no obvious effect on the tone quality by itself - or none that I particularly noticed. If there was a change, it was an improvement (it didn't seem to need voicing as badly as I thought it did Monday, but my ears and perception can easily change that much from day to day). So I think I may have hit on a winner. I find lanolin much preferable to fabric softener, as it is a natural product that was originally in the wool before it was processed. I have run across lots of hammer sets with this same problem - they aren't all that densely pressed, but getting the needles in is just too much of a struggle, and it seems to tear the fibers more than spread them if I force the issue. Pull out and there is a nice hole the size of the needle, and the tone is still constipated. With the lanolin, once the needle is pulled out, there is little evidence it was ever in the felt: the felt fibers move back.
