In mathematics and engineering, positions within three dimensions are often referred to by coordinates that are measures against the x, y, and z axes. The Gorse Fox knows this. Indeed he has used this many times over the years when programming drawing and engineering tools. He introduced computer aided design and numerical control software to British Aerospace back in the 70's and had the second installation in to whole of the UK (after Pressed Steel Fisher) of the CADAM tool that was so widely used in aerospace and motor manufacture.
Why is this relevant, you may ask. Well, the Gorse Fox started to build the floating shelves. He was eager to use his new jig, but there was much preparatory work to complete first. Eventually everything was measured out, the wall brace was cut, dados were let in to accommodate the "fingers" that would support the shelf. The jig allowed the pocket holes to be cut and then the dados were glued and the fingers inserted and screwed in. This is where the Gorse Fox should have remembered the X-Y, and Z. He actually only remembered X and Y. He concentrated on getting the fingers absolutely square to the brace (the horizontal plane), but forgot to check they were also square in the vertical plane. They were not. By the time he noticed the glue had set up and the shelf support could only be used for scrap - otherwise any shelf would have looked twisted.
The Gorse Fox made some templates and jigs. He started again. This time he used the jigs to keep the components square in both the horizontal and vertical axis. A precious lesson had been taken on board.
Work will continue tomorrow!
