I bought a vernier caliper cheaply from the local flea market.
This instrument is robust and accurate but it has stains that make it difficult to read.
I will take the caliper apart, clean it and put it back together.
After that I will show what this vernier caliper has to offer and how to read it.
Reading the metric scale is a no-brainer to me but the imperial scale is confusing.
I will try my best to explain reading of the imperial vernier scale as well.
