Blueprint 101 - Using Micrometers, Calipers, & Bore Gauges

THESE MICROMETERS ARE PROPS. They're cheap, easy-to-read, and they were defective straight out of the box. They couldn't be calibrated. The graduated sleeve was seized up and rusted to the bodies of each one. They're also not accurate enough to measure taper or runout on a bearing journal which is necessary if you're rebuilding an engine. If you're going to rebuild an engine and you're not already familiar with these kinds of tools, this video is required material. None of your measurements mean anything if they're not accurate. I illustrate the calibration and use of 3 major tools needed for taking measurements, and a brief demonstration of how they work. These are by no means the ONLY ways to use or calibrate these tools. This is simply the method I will employ to measure parts in later videos so this instruction doesn't distract from their intended messages. Even if you're familiar with these tools, you may find something useful here, or even be able to correct me and my rusty skills.

When I can afford a $1200 set of Micrometers, I'll re-make this video.
