Drilling the Greddy for 10mm question.
Okay, so the fellow I gave the turbo and manifold got the drilling and tapping of the manifold right as I can thread the 10mm studs into there, but the studs don't fit through the holes he drilled in the turbo. It's close, but not quite.
What size drill bit should I be using for this if I attempt to enlarge the hole? I'm looking at various tables online and I'm not really clear on this.
Also, I probably need to bring this to someone with a drill press. Hm, looks like a cheap drill press is $125 or so.

Buy some $6 calipers at harbor freight. Measure the OD of the studs, then pick a bit that's barely bigger than that measurement.
You shouldn't need a drill press, the new drill will center fairly well on the current hole.

Drilled it out. Unfortunately, the guy who did the holes for 10mm in the manifold didn't get one of them lined up properly. Won't work. I can't see maybe half the stud hole when I line up the other three. Criminy, this is why you don't use friends to help out with this crap.
