Armenian producers piano "Komitas" probably tried very hard to make his original upright piano but the holes for the strings need to be drilled out correctly. To tuning the piano, and not torture yourself boondoggle

Thanks, Max. A few American makers have turned out a few uprights with pin crowding too. Makes tuning a little more challenging.

Hi, Bob.
I thought that in America such bad things can not do that because you lives always in capitalism. However, I believe you.
A pins's crowding is certainly an inconvenience for the tuner, but the piano "Komitas" which as you can see the clip installed unacceptably sloppy. It's made without hands but foots only. A ability to tuning this piano is great art. But we are looking for smooth paths

It's true, Max. An occasional new Baldwin upright arrived from the factory with the problem. (Pre-Gibson era.) Not as bad as the "Komitas," but bad enough. Setting both the pin and the string is not easy, but not impossible either.

It's sad, Bob.
Please explain what it means (Pre-Gibson era.)? What happened in Pre-Gibson era? It has something to do with the lack of quality control in United States factory? Some cases need ignoring this situation as follows. I install instead of pair of strings only a single in every pin

Hi Max, I believe it was 2001 when Baldwin went into bankruptcy and the assets only were purchased by Gibson Guitar Co. By "pre-Gibson era" I mean Baldwin pianos made prior to 2001. After Gibson took over Baldwin, the Little Rock, AR Baldwin dealer for over 50 years dropped Baldwin and switched to Steinway, so I have absolutely no experience with the Gibson Baldwins.

Now me clear. But pity that era Gibson so negatively affected the production of the American vertical pianos. If we start from the name of the new owner is a "guitar manufacturer".
"What's good for the lute, does not always work in the piano" (joke)

Thanks, Max.

I lost the pics but I have seen a Grotrian Steinway grand, where one pin was really misplaced.

The closed the hole with a plug, then the plate with some mastic painted as the rest, and bore a new location for that pin.

Mistakes can occur when the pattern get old, or the machine have a bug.
I also have seen a plate screw that was screwed in nothing and was protuberant 2 inches under the brace. That one I never understood (was on the perimeter just below the pinblock).

I have read a thesis stating that the Aeolian factory, when buying many other brands and producing mostly pneumatic, did induce a lowering in quality, because with pneumatic s, the level of acoustical and touch quality is less important.

Aeolian where the "Microsoft" of pianos, and they are pointed for responsive for that. The these state that pianos begun to be build with lesser grade wood/components at that time.

croatian(Grotrian) piano master corrected his mistake and it was single hole

But I don't think Aeolian had the number of US Government contracts to subsidize it like Microsoft does.

That is truly nasty looking. There are no other words to describe it.

The main danger is factory wedlock installation pair of strings. That the string is forced to lie on near pin so increases load. This results in premature failure of the bush and the holes in the pinblock. Fix it impossible
