We were recently asked to build some custom tables for a 40' Sabre Yacht. The first table was for the settee next to the helm station. They wanted a table that would support a laptop and swing out of the way and be removable when they didn't want it at all.
The leg is carbon fiber over pvc pipe with the base squared off to prevent it from rotating. The bracket at the top is built up from fiberglass with a locking screw built in to fix the tables orientation.
This is not a great picture, but it is the fiberglass receiver which mounts under the step into which the leg goes.We are clamping the glass between forms to form the bracket.
Below is the top bracket in progress.
Here is the leg hole. The receiver bracket is screwed and glued to the floor and the two vertical pieces of the settee under the step. We had to install this through an AC register. Not easy at all. You can see the edge of the fiberglass receiver bracket in the corner. The squared off bottom of the leg is tapered slightly to permit easy removal and installation.
A little teak plug to cover the hole when the table is removed. This is before the plug was varnished.
The owners did not like the standard dinette style table and wanted to put a larger TV in. We took out the cabinet that the original TV was in and built a new cabinet that was only deep enough to hold the electronic audio visual components. I met with the Missus and came up with a design that she approved. We were almost complete with the installation and she said well you aren't going to put that there, are you? (This being the knee to support the table as per the drawings she had blessed). So she didn't want the knee. I then designed a bracket that mounted onto the wall and cantilevered out to support the table. Having built several tables of this type the structural design standard is whether it is strong enough to have a go on or not. She laughed and said it indeed needed to be that strong. We built the bracket of Divinycell foam and fiberglass with some carbon fiber applied for extra rigidity. We painted it black and attached it securely to the side of the house. We screwed and glued the table top down to the cabinet top and bracket.
Here is the table with the extra leaf in place. The owners were very pleased with both tables.
