Ray, what you say above here, about the stuff on the griddle being balanced, and if it ain't near perfectly balanced, and you're carrying it, its comin off. WELL, that reminds me of splitting hogs.
You got the hog hanging there, and there is one hook in each hind leg, and those hooks are at the ends of a short steel piece, and that short steel piece has a hook on it, just one hook, right in the middle, at the top of the beam, SO, now you need to split the hog right down the back bone, and you better be pretty close to splitting him equally, because both halves must hang on that beam now, if one is too heavy, its goin to the floor, and the light one goes in the air.
The same way your food would do if you carried it on that griddle, unless you have it balanced out very good, and the practical thing is, you don't think about how you're gonna balance food to carry it, unless you are one of them waiter carrying that great big tray, with about 1200.00 worth of food on it. ;D
