Dial bore gauge VS Telescopic gauge - How to use and calibration. Measuring a cylinder

Dial bore gauge, what are they and how do they work, in this video we'll see how to calibrate them and how to measure using them. The main use is in measuring a cylinder or a bore. measuring out of round, measuring taper or irregularities in a cylinder or any bore.

There will be a comparison with the measures taken with a three points micrometer and a direct comparison with a telescopic gauge.

As a very important part of measuring with high precision in a small machine shop or in a hobby situation, I'll talk about some precautions for proper handling in order to get the best possible results.

By using a cylinder bored with a special preparation we'll also be able to see how we find out defects in machined parts.
