Neither do I, but I know that when it comes to welding tables, size
and thickness matter.
Your table is probably small. That's why 3/8" plate is OK.
For a large table like 7x10, 3/8" plates would have hard times staying
flat and straight, unless they had solid frames underneath.
I have two welding tables for small stuff. One is a Lyon workbench,
and another is a cart with 3/8" top. Works fine for me. The big stuff,
I weld on concrete floor. ;-)
I love this business, getting plates from one place, legs from
another, doing some welding and making money. I am also thinking of
making blacksmith tools. Something where $5 of labor can be parlayed
into $30 of added value.
