Transform a surface gauge into a squareness comparator
All of the videos I make are intended for apprentices and people that are new to machining
I am always surprised when meet a certified tradesman that does not know how to do this
In this video I will demonstrate Checking a block to see if it is square
A squareness comparator is an essential tool in any machine shop.

Cosine error...
I think you mean within 10 deg of the surface being measured, not the body of the indicator.
Tip angle referenced to the indicator is irrelevant, that is why they are adjustable.
I may have missed it but the part HAS to be parallel to check this way.
Good video though.

you are correct
I am going to edit the video and re-post in a week
and add the sides must be parallel before checking squareness
thank you
