Well, there isn't much concept or design here, but when one of the local tool stores was redesigning their showroom, they were selling these really nice, rock-solid tubular steel bases for $75. I would have bought more than one (they had dozens) but "local" at the time was Downey, CA and the shop was the garage - no room for more.Anyway, on top of the steel base, I placed a 4X8 sheet of MDF; to that I added a bunch of drawer pockets attached with bisquits for side access on both sides, and on top of that I put another sheet of 4X8 MDF. Finally, on top of all that, I put a layer of Formica (I keep the whole thing covered in kraft paper and replace just the paper when the glue, stain, etc... get bad. The ends have through and through openings at either end for storing pipe clamps, and each corner has a removable solid piece so vices, etc. can be attached to the table top. The whole thing is on a mobile base. I use another bench with real vices for heavy work, but this table is great for assembly and moderately heavy work - everything I need is right close by in one of the drawers, and bigger stuff rests on the bottom shelf. Here and in the next few posts are several pictures with descriptions (first one, attached here, is top/side drawer construction):
