Ok, here is my solution to the unflat router table. Tell me if this makes sense. After the adjustments are applied, I’ll screw on some bracing so the table won’t sag…
And yes Forest Girl, I’d love to buy a new router table but…
View Image The table is 1.25″ thick medium density particle board with a mahgony veneer on top. It was a “cutting block” from the top of an old Maytag “portable” Dishwasher. Total sag is about .010-0.015 from edge to center. I figure two strips of 3/4″ oak and some beefy screws and I should be able to correct the bow. I can fiddle with the height of the fulcrum to get the adjustment just right. Then I’ll glue and screw on some bracing next to the spring boards to hold everything in place and remove the spring boards. I thought about just clamping but I don’t have a big (or strong) enough surface to clamp the table top to (with a fulcrum in the middle). Anything I clamp to will flex. Mark
Measure it with a micrometer, mark it with chalk, cut it with an ax.

Well, I used this technique and got the table wihin about 0.003.
I'll check it again tomorrow to see if it holds. I used two 1" by 1.5" pieces of solid oak as braces - urethane glued them and screwed them to the underside of the table while my flex rig was still attached. It should hold...

1/100 th of an inch? across the whole table? You are worried about the wrong things. Your stock will change that much in 24 hours. That amount of sag is not going to affect anything. It is more importaint that the collet is perpindicular to the table.
