Update 1: grand piano's hammers come in three weights and two wood core sizes, which can fit 80% of the pianos you can meet. There is also a universal hammer, which can polish the wood core by itself, and is suitable for the remaining 20% of hammers. There are two basic styles of vertical hammer, which are suitable for almost all harps. What else is there? Piano manufacturing, tuning is a part of it.

Update 2: Is there a whole tone in the middle?

There's a whole sound in the middle? After the tuning work is completed, it is the full tuning work. The purpose of this work is to make the tone and volume of the whole range of the piano uniform and tidy, and to show the unique vitality of the whole piano. The whole sound mainly has three tasks, namely, shaping the hammer, smearing the hardener and needling. The first task is to sort out the correct hammer shape, so that the felt surface and its tension are unified, and the pronunciation and timbre are uniform. The purpose of the hardener coating is to increase the hardness of the felt, thus improving the situation that the felt is too soft. As for acupuncture, it is necessary to correct that the felt is too sharp and too hard, so that the fibers of the felt become soft and the timbre becomes soft. At the same time of the whole tone, find the best volume of this tone as a reference tone, and then adjust the overall tone and volume according to this reference tone.

Thank you for your tidbits about Abel.

I don't know their connection. My first contact with Abel parts was with a Japanese piano repairman who specializes in repairing19th century polyphonic pianos. I am not an expert in this field.

But I did see Abel technici's excellent T-rivet and cover on the old hammer.
