My cousin is a CNC machinist. In the past he has made artificial replacement joints and stuff. This morning, he texts me and tells me that the parts he is machining are really eating up his tools. I text back asking what he is machining, to which he replies "castings". I asked for further clarification, and he replies "well, forgings". I finally just asked "what are you making?". He replies they're parts for Delta commercial aircraft brake assemblies. I texted back "Make them right!!!" He texts back "Don't fly Delta!! Lmao". Fear not folks, is actually quite good at what he does.
