10 x 5 foot plasma table build

[ned]

I have come up with a solution.

weld eggcup onto bottom of steel beam 1.

weld ball onto bottle jack.

fill eggcup with grease.

do this on 4 corners.


This is presuming that:

A.
The top surface of steel beam 1,
and the bottom surface of steel beam 2 are within a reasonable tolerance.


B.
The beams are straight. The shorter beams of the rectangle will have to be a very straight.

The weight of steel beam 2 will keep them orientated.
Now measure with spirit levels and adjust with bottle jacks. Repeat until correct.




When happy weld steel beam 3 into place.

Remove steel beam 1 as it was only ever a support.
