Big Green Egg Table - Lower Shelf Assembly

The legs turned out nicely so now it's time to move on to the lower shelf that the egg itself will sit on.  The plans call for just 1x4's but I'm gonna over do it and use 2x4's for the frame.  It will help me sleep better at night knowing that I will not be woken up by the sounds of shattering ceramic.  I'm sure the 1x4's are fine for holding up the weight but like I said before.  Over engineering is my thing.
After a few hours I managed to whip this up.
