Every time I go to slice a piece of meat, I get "the flap" at the bottom and I have to rotate the piece being sliced. Looking at it, I blame the slicing tray being too far from the blade and not supporting the meat, so the bottom edge falls away from the blade rather than being cut. My solution (which is as of yet unproven) is to bond a 1/8" sheet of HDPE to the slicing tray and close that gap so that the meat is better supported. Here are my before and after pics. Before, the gap is about 3/16" and after it's under 1/16". It should make for more trouble free slicing.
