x2 Aluminum tubing laid perpendicular the long axis of the table to have lev

xaggerated by a sloping garage floor. I did weld up some screw jack levelers
for the table that hold it steady and get it near level but I still need to
address the twist. I have flipped the R wing, right side up and want to dri

ar but I want to ensure the 2x2=99s are level in the X and Y before st
arting.

ong the length of the table. I have thought about buying or renting one of t
hose self leveling lasers, using an optical level and even a piece of clear t
ube filled with water or some other fluid. I may be over thinking this for a
CH-701, so I wanted to see what others have done to ensure they are buildi
ng on a level surface.
