No Problems , with my screwed and Glued AlAn as far as the Italian BB went, had a Loose Ball
Campag Square taper one , Triple crank as a 50,36 double..

and now with its replacement, a Pinarello Cross with a <C> Race Triple Crank, Campag's square taper Cartridge BB.


Odd thing about them is 36mm but the thread pitch is 24tpi, in inches because after WW2
to rebuild their industries they got US made machine tools , and US lathes have a certain
Lead screw pitch to cut Threads.
Lathes to cut metric threads have a different pitch, tool feed screw.
It runs across the front of the Lathe.
