A bit off topic, but I was staring at a stainless steel sink I am about to fix in, and it just crossed my mind just how do they make 'em?.
A press suppose, but how do they get that deep depression where the bowl goes without stretching the metal?. Or do they make them in smaller bits and weld them together?, surely they don't cast them at all, so how's it done?.
Google doesn't seem to know.....
