Gday

I've read a few times about the method used to make straightedges in the workshop using threee workpieces & continually checking/filing/swapping/adjusting them against each other to get a reference straight edge.

For woodworking the following idea is a much simpler version of the same I reckon., as shown for checking jointer tables, router fence, whatever.

Should you see a need you could put more screws in than just the three.

It's a fairly large attachment so as to make the concept clear.

It's out of "The New Best of FineWoodworking - Workshop Machines". Fairly new release at our local library, & a good read.

I've got a Veritas aluminium straight edge (24" if I recall correctly), but David Charlesworth has the view that only Starret make REALLY straight straight edges.

I'm afraid my woodie skills aren't up to <0.001" tolerances though...

I have the Veritas aluminium straight edge. Guaranteed to within 3 thou over the length of 36". With wood that moves so much, who needs more accurate, and that includes setting macinery. My humble opinion.
