Measure With Micrometer. Mark With Chalk. Cut With Chainsaw.

I am sure you have seen this before.   Not quite where I ended up.  I figured out to get my mill to cut a 1.01" ID hole.  But I need something that goes on a 1.2470" shaft.  Fortunately,  unlike surgeons trying to do the second undo on genitals,  I have material left with which to work.  Just code a 1.25" hole,  .25" left of the first hole.
