But I'm not happy with the DVD as it has no sound. It only had sound on the section about honing and such but that is all. So when I get it to my shop and set up I will use the instruction manual to set it up. I think I'm going to be happy with it instead of the wooden one I built. Have a look.... Oh yes, the big platform is under that white cardboard. I took it out and it slipped out of my hand on the glass table top.. Thank God that did not break.....Fay
