I used it for work when I was a toolmaker, so I had to be precise. If I needed to be more precise I'd use an edgefinder on both sides and split the difference. That only works with a mill, though. If I needed it to be within 0.0005" I'd use my indicator, but that's a whole different ballgame than garage work.
I'm not a toolmaker or even a machinist but I do the same thing. Within .005 I use a ruler. Within .001 I use an edge finder. Indicator for anything closer which for me is rare.

). I got up nerve and reupholstered a chair we have. To me it wasn't difficult. I'd love to have one of those industrial sewing machines like they had.
