Is there a standard size for the cut out on a jewellers bench. Nearly finished making a new bench, but the bit that I have cut out seems small. I bought 2 sets of flat pack drawer units and a big slab of 25mm ply. I screwed a piece of 2 x 2 timber to the wall and screwed the ply to it and then screwed the ply to the drawer unit tops. It seems very solid but have a GRS. and can't seem to get a good size cutout. I think it was Caroline suggested using a dustbin lid, not sure how big a dustbin lid is.
