Thanks all you fine folks who convinced me to go with a large vs a medium in my earlier post! My table is well underway and it takes a little of this and that from plans I've gotten here and a few of my own woodworking preferences. My question though has to do with the space between the TOP of the TOP shelf and the TOP of the bottom shelf. The only measurement I have seen is that for the large the hole is 21" in diameter and the depth should be 17"...yet the instructions go on to suggest that a concrete stepping stone be placed on the bottom shelf and then to compensate for its thickness. Does the 17" include those three liitle feet that the egg sits on or did those little feet come along later so the stone isn't needed? Thanks to anybody who helps me by measuring...I want SO BADLY to push my Ducanne into the ravine behind my home since I'm too nice to place it where the doesn't shine in the salesman who convinced me "Buy a Ducanne..it will be the LAST grill you'll EVER buy!"
