So here's the COMMON theme amongst most all of them:
They're
HEAVILY built - with big heavy tops - heavy legs - and they're sturdy.
I don't want to see any more METAL working tables with particle board tops - that's just WRONG!
SO get busy building already!! You're over thinking it.
By the way - the 4' X 8' X 1/2" sheet I started with - weighs
NINE HUNDRED POUNDS -- so be prepared to lift (somehow) some very heavy stuff! When they loaded the sheet in my PU -- I had them put some "dunnage" (I brought with me) UNDER the back end... I then welded D rings on all 4 corners... Hooked it to my hoist - and slowly pulled forward. I built mine upside-down and then tilted it on its side and then once more til upright - using my lift.
I found that if I put the cheapy car dollys under each leg at one end - I can lift the other with my floor jack and move it wherever I want to.
