I want to "level" the cast iron wings with the central table on a table saw to align them all in the same flat plane. It is part of the assembly process. I have several good quality metal rulers up to 18 inches, two inexpensive metal meter sticks, and two Starrett 12 inch combination square blades. The problem is that the combination square blades and rulers are too short, and I am not convinced that the longer meter sticks are straight enough for this job.
I would like recommendations for inexpensive local sources to find a "perfect" straightedge. Ideally, it would also serve as a imperial and metric ruler, but the straightness is critical with an error of a few thousandths at most. I need something that is reliably straight.
The table saw flatness is rated at 10/1000 inch across its surface. The wings are rated at 20/1000s across their surfaces. According to the manufacturer, you can use clamps or body weight to align (tweak) the somewhat malleable cast iron wings as you tighten the screws that attach the wings to the table and fence rail.
I thought about buying a 24 inch Starrett combination square blade. It is short compared with the ideal 30 inches, but might have many other uses over the my lifetime. Unfortunately, they are expensive.
I hope that someone here can suggest a quick, easy, inexpensive, and reliable alternative.
P.S. I should have made the subject "Flattening Table Saw: ..." instead of "Leveling Table Saw: ..." I hope everyone understands that I want to make the table saw table and wings flat relative to each other, not really "level to the ground."
