Table for my mill

[Vinny]

Back to this. I decided to use some of the previously cut steel for something else and bought some 2" square tubing for this. Weather permitting, I want to cut and weld this up tomorrow.

Below is a crude drawing of what the top will look like (except square corners, dunno what I missed there). My question is one for strength. It will be sitting narrow side toward me. The mill will be bolted to the back and middle pieces. I plan on cutting the pieces square, not 45s. The legs will, obviously, be in the 4 corners.

For strength, should the back one be welded to the top of the legs or will be be strong enough to hold the mill (about 300-350 lbs) if I put the two long pieces on the leg tops and weld the supports to it? The middle one can't sit on any legs so it'll have to rely on the welds.

The square tubing is 1/8" thick, if that matters.

Here's the crude drawing...
