Intake hole please help

He calls himself a machinist?? Where are you located, as I've been an un-employed machinist for 15 months now?? I have over 25 years as a machinist and would have never done something like that!! Most machinists will ask thorough questions, so as to NOT make that kind of mistake!! How the hell this guy still has a job is beyond my comprehension. I thought after all of the economic problems we've had, that these "so called machinists" were all weeded out. Damn it all to hell, now I'm pissed:(
