Good evening
i noticed that even though the keyboard has been felted, the problem of incorrect distances between one key and another has not been resolved, and they are not even completely stationary, what should be done? was the work done poorly or does something else need to be done?

The measurement of the cauls, i.e., the calibrated wedge that clamps the cloth onto the walls of the slots (mortises), may have been incorrect. The thickness of the cloth must also be chosen with care. The spacing must be correct by orienting the front oval pins of the keyboard. Now, to make the keys firmer, these pins can be rotated, but this should be done halfway through the life of the felt. Doing it now means somewhat sacrificing the life of the felts themselves. Instead, the center-keyboard guide ones cannot be corrected except for their verticality (which regulates the perfect and uniform horizontality of the key surface). There is no possibility to correct any play. The replacement of all these gaskets must be performed while warm to ensure minimum play on the pins and the perfect verticality of the mortise walls (See my tutorial)
The Cashmere must be of the highest quality and hot glue must be used strictly, as it is the only one that does not penetrate the thickness of the felt, which would otherwise make it, as in the case of cold glue, too hard on the friction surface side. If maximum smoothness is not achieved without excessive play or non-uniform play at different key depressions, the work must be redone. It is also important to check the wood tolerance on the central holes (where intervention is possible)
I hope I have been sufficiently clear. Regards
