Hello Rick
Haveing a master square is a good idea. You can use it to check
other tools and setups in the shop.
I need to make a good stright edge for checking stuff.
Get some ground flat stock for a starting point, that would be good.
You write good ideas about things.

"The Machinist's Second Bedside Reader" by Guy Lautard presents a process
for making precision squares from non-precise forms. What I found lacking
was an explanation of the theory behind this process which essentially
creates precision where none existed before.
Those with a fear or even hatred of math have no reason to stay away from
this article. My goal was to engage both the experienced machinist and the
person new to our hobby.
