Mr Al should be careful about breaking stud mount rectifiers. Some of them contain very toxic stuff. IIRC it's beryllium powder in the ceramic. Very bad to breathe.
My memory might not be exactly correct, and the contents might have changed since the 1970's. I just memorized, "Never bust a ceramic semiconductor case".
