For those who are not carpenter or engineers or trades that require to cut angles and have wondered why when using a mitre saw your angles do not work out or when you look at the scale on the mitre saw that the scales are different on each side. I was researching some information and come across this youtube on cutting angles on a mitre saw. Out of interest I watched it. Haven worked in Mech Eng for many years I did learn something. It was angles and mitre saws.
Here is the link and it just makes sense. Of course this is aimed at the beginner or a reminder to others
