A tap can only remove material, and may leave the threads too loose to secure the cup. Unless the shell is Italian thread (I did notice that you mentioned you were located in rural Italy), you can ream a metric or English thread shell and tap fresh Italian threads. If it is already Italian thread, your best bet is to use a threadless cartridge, which are offered by several manufacturers.
