I suppose here is as good a place as any.
I have a few welding tables I made that see regular use in my shop.
The first is my 48" x 120" x 1.25" top main table. I built this a few years ago to replace a similar table, but with some upgrades. I had the top blanchard ground, and its drilled 12" on center for hold down clamps. I also have a Kennedy toolbox and blueprint file under it for storage. There is a link in my signature for the build.

Next is my "mobile" welding table. I made this one from all aluminum, and it is quite a bit smaller, 36" x 48" x .75" top. This table has a no holes in the top, and is light and easy to move around or take on a jobsite. I use this one a lot for small work, like small stainless parts or things where having the aluminum top would be beneficial.

I also have a small cast iron table I got as a pile of scrap, and repaired it into something useful. Its maybe 30" x 60" or so, its a bit of an odd size. Its also low, so its kind of handy for tall or awkward shaped weldments.
