Sorry forgot to post finished. My brother decided to go with a basic open frame to support the weight that also allowed him to put slats in to support pots and pans. Mounted on casters for mobility, the block is also gravity mounted so it can come out of the frame if desired and as the pots are supported by running slats the block bottom is flat and clean
When my kitchen is done we also have a dozen or so multi wood cutting boards to work on before easter
