Made a 1/2 solid, 1/2 open box. Rests on 2x4s, isn’t fastened to the legs even, my thinking was to let the torsion box find a plane it wants to rest on regardless of where I roll the table on our lumpy/uneven floor. I can clamp the ‘loose’ corner to stop torsion box pivoting/moving/twisting. Hope that makes sense? No idea if this is good sense. I don’t care if the box is true level or not, I mainly want all four corners to be on the same plane.
Should’ve made surface large enough for laptop, beverage and a few tools could be spread out while CNC is working away. Ended up a making removable shelf to precariously place the laptop…
Space is tight/premium for me, so it’s nice having the Vac, CNC tools, some small stock pieces all on the same rolling table.
