I noticed some of your posts about welding tables and decided it was time to upgrade my little 3'x3' x1/2" table.

I went to my local scrap Guy and picked up a 4' x 8' x 1" thick a36 steel plate for $190

Only a slight bend in it. Anyways, I have some 8" I beams I cut to support and fully straighten the table out with but..... I am Out of beams to use for legs...

What do you guys suggest to support a big heavy table like this? Scrap Yard is out of beams, and I dont want to shell out $$$ at the local steel yard.

Basically, what would be strong enough to support 1500-2500 lbs when loaded?

I was thinking 4" square 3/8" wall tube should suffice, any ideas?
