Looking to tune up my equipment: jointer, TS, etc. I bought a square at HD; the kind with one metal rule side and one (fiber? plastic?) base.
Well, the darned metal piece moves inside the base, so I have no idea what is supposed to be "square"! What good is a square that moves inside the base? And why do some of them actually have a screw to adjust it? (this one does not) What would I use to square a square, anyway?
Do you all have any suggestions for a *definitive* "square"? Why are some solid and others not? I've seen "precision" and "super precision"...
What's the difference?
Hep me!
