Something that really surprised me was cheap feeler gauges from Wal-Mart were actually accurate when measured with 0.001mm or 0.0001" micrometers. I compared them to Snap-On and Starrett which were 10x the price

sometimes tooling is just junk other times it’s the cheap brand of the namebrand Back in the day when you used to know where things were manufactured, I would order parts and talk to the sales guy and find out wow this square is made in the same place as the sterritt squares are made Thank you for your comment and thank you for taking time to comment. It is much appreciated. Ray

I would point out that everything we do starts with the surface plate. Something flat has to come first or there's nothing to go back to. What you could be checking there is how flat the stone is

Thanks for posting, very interesting! I’m going to have to try that light thing and see what’s actually going on. As others said, easier to get the feeler gauges out than trying to do the light thing in a properly scientific manner.

Yeah, the difference between the red & blue is 300nm which I believe works out to just under 0.3 of a micron or 0.0000117". I don't think the human eye can see that😁. The use of feeler gauges is pretty good & easy. Cheers

Hi Peter I’m glad you understand my frustration when dealing with certain people Good luck trying to tell people they can’t see color And they also think that if they can see red or green or blue it’s like 2000s of an inch Thank you for your comment much appreciated Ray

Thank you! Great video. But, why did you didn't start measuring the orizontal 2.5 inch from the very left limit of the square and instead you started measuring from the intradox?

Of course, your square is only calibrated to perhaps 1 thou over the length unless you know for sure i.e. have measured the squareness of your measuring device somehow.
