Good Evening Ladies and gentlemen. I wanted to pose a quick question on how one would find the exact opposite location of a sphere to drill a hole? I could get pretty close with measuring instruments, string or other rudimentary items but what if I needed to get within a thou or so? This is just a general question and I don't have a particular problem to solve but would like to hear suggestions. Where this question stems from: A buddy of mine wants to drill/tap an 8 ball for his gear shifter. While working on that I was thinking ' What If I needed to be crazy accurate on a different project say for space X for 1 million dollars but needed completed in 2 hours? I don't know how I would get the opposite location with extreme accuracy. I'm very Interested in hearing thoughts or techniques on this. I have done a search but couldn't find a technique for the above problem. Lots of stuff on drilling through the earth but that's for another topic.
A rotary table and some sort of live center with a cup on it that the sphere would fit into and centered below the spindle?
Then rotate it 180 degrees on the rotary table?
Just a fun puzzle.
