I was helping my boss clean out his basement this afternoon, and noticed an interesting flooring detail. I have seen many floor boards that have been adzed for proper thickness over the floor joist. These floor boards had been shiplapped, and on the underside of the shiplap, they had put a 1/2" wide rabbet down to an even thickness. It was only about 1/16" to 1/8", depending on the flooring deviation. They then used this as a guide for the adze work. Kind of a neat approach. Has anyone else seen this?
