Not a newb question. I'm designing one out of 3/16" plate. Have a 4x10 sheet of it in the shop. It'll be entirely too heavy all one piece. The sheet I have weighs over 400lbs. I'll keep everybody posted when I get some round to it in. That stuff's been on backorder for a loooong time. So, don't go holding your breath till I get something done.....
