Redtail, that is a creative solution.
Am curious to know what the OP fazer has figured out to solve his issue.

After many years, I am planning on returning to using my building table. ARFs are to blame.
Am certain that its surface will need some leveling adjustment. If necessary, I can't use a jack stand as my table has casters to move it around in the man cave.
Replacing the 2X4's with new ones would be my route as my table's corners utilize metal brackets and wood screws. Hard part is going through all the 2X4's in the store to find straight ones. A solid core door will go on top.
