I had forgotten about the April fools gag in the Journal.
I've got this crazy idea of having two different sets of hammers with different weight profiles for a concert instrument, and some less invasive way of adjusting front weight than adding and removing swaged lead slugs.
I'm frustrated with a couple of sets of overly massive Steinway hammers that are nowhere near the end of their service life, but I want to leave options open for my successor, whenever that eventually comes about.
A couple of my predecessors did some wippen swaps, but archived the old items. I have been the beneficiary of that foresight.
