while I was attempting to tune my piano, I snapped a tuning pin and only after buying an extractor was I able to unscrew it. Now I am asking you: is it enough to just get the same one and screw it in, hooking the string before reaching the bottom, or does something else need to be done?
Thank you and best wishes again

Anyway, if the original pin was a bit loose, it is necessary to find one of a larger size; otherwise, it's fine as it is.
There are two philosophies that correspond to two ways of working even in the factory: there are those who wrap the string around the pin and then drive it into the capstan with a punch and hammer, and those who prefer to screw the pin in from the very beginning and then put the string on.... and continue screwing...
Generally, the curl is 3/4 turns, so it is always better to pull the string with a pin that is slightly "increasing" compared to the others and then bring it to the same level as the others with a punch and hammer... if instead one makes a mistake and it should be "decreasing" compared to the others, after the string has been screwed in, it could no longer be extracted.
Whatever the method, what matters is the result; on the bass side, if you need to strike the pin, it's better to put supports under the capstan, on the treble side, the under-capstan holds by itself.....
Yes, everything is clear, but to avoid making a mistake I am asking you if I can proceed like this: since the string already has its 3/4 turns of curl because it is the old one... I hook it to the ankle, strike it with a hammer and punch until I bring it slightly higher than the other ankles, and then screw in just enough.
Thank you

Yes, but you recover the entire loop of the old string if, while loosening the tuning pin, you tension the string, it comes off straight.... Consider that once the loop is fixed with the string already under tension, after screwing in the tuning pin by 2 or 3 turns, if it remains higher than the others, you can still re-hammer it to bring it to level; however, if you overdo it from the start by inserting it and it ends up lower, you can no longer extract it.
