Metal Selection for Machine Stand

[fursphere]

Going to weld up a stand for my PM-30mv mill. With vise, it should be around 600 lbs.

My first thought was to get some 2x2 square tube steel, 3/16" thick, and then build a frame around an old craftsman toolbox (stand will sit on the floor - toolbox will just sit inside the frame, not part of the structure). Something very similar to what this guy did: Stand build

Put levelers underneath. Set the chip pan on the top of the stand then bolt through.

I tend to way overthink things out of habit. Is 3/16" thick enough? Should just go thicker with 1/4" instead?

Thanks in advance.

3/16 should be plenty. Mike

2"x2" 1/4" wall is a monster, maybe only for the top front and back support. I used that size for the PM833T which is a heavier mill.

3/16 is plenty as said. I built a scissor lift table for my John Deere lawn tractor. No problems.
