I have an idea for the rotating mat! I purchased a lazy susan...you know the big ones they use to put on the tables and were made heavy duty...from a garage sale....then I glued an old cutting mat on it and trimmed it to the size of the lazy susan. Works great!....another way is to purchase a heavy duty lazy susan mechanism from maybe a wood working store, and a piece of plywood screwed to it. Anyway, give it a try...it would not cost as much as already made.
