I did not chime in at the time, but I know there was an exchange in which a technician was asking about removing a spoon from a wippen; or installing a spoon.
A lot of folks seemed baffled (if that's the word) as to why anyone would WANT to do such a thing in the first place.
I have myself attempted to mix and match wippens on an upright that I had no spare parts for.
Realizing that the c8-wippen was not absolutely a necessary part; I removed such and tried to use it to replace the c-4 wippen, which was very worn out.
Sadly, my c-8 wippen did not HAVE a spoon.
On my (and I gather on most, even grands) piano the very highest notes have no dampers. Therefore the wippens have no spoons.
I tried to remove the spoon from the worn out c-4, but it was extremely difficult.
Installing a new spoon in the replacement wippen also would have required drilling a hole and placing the spoon and gluing it with the possibility that the whole process would not work.
Without spare parts, a piano tech find herself in the position of those (legendary) auto mechanics in rural locations who get a broken down car's carburetor running using bubble gum and a straw.
