I've just been tasked with setting up a new welding area at work. There are four 5x8 platen tables used in line for a 40ish foot workpiece. I would like to align and level the four tables such they can be used as one fixture/alignment surface. Anyone have any tips and tricks for getting lined up? Right now my plan is strings/wire, all the levels i can find, and a floor jack.
Seems like an obviously tedious task, but if anyone has a smarter not harder method i would greatly appreciate it.

Thanks,
Brian V.

I laser would be a great tool for that. I got one of those Milwaukee line lasers and it has been very handy. A few steel wedges you could drive under the legs and then tack after you get everything the way you want it might help too.
