Bahoukas received a beautiful collection of calipers and micrometers recently to add to some we already had. It’s a wonderful collection.
Don’t know what they are?
Calipers were used as early as the 6th century BC by the Greeks and Romans, according to Wikipedia.
The first ever micrometric screw was invented by William Gascoigne in the 17th century, as an enhancement of the vernier; it was used in a telescope to measure angular distances between stars and the relative sizes of celestial objects.
Here’s a detailed video with information for both inside and outside calipers and micrometers. Most likely, more than you ever wanted to know unless you’re a user of these great instruments. But a perfect primer for appreciating these amazing instruments.
Now that you know all you ever wanted to know about calipers and micrometers, stop in and visit to view our collection. Rain or shine, yep, we’re watchin’ for ya!
