However I needed to make something that would not look out of place againts the rest of the furniture in my house.
The timber is shop bought (about £120) of oak and black walnut.
I apologise now for the lack of photos of the construction but I have attached a detailed sketchup model and plans for each component.
Have fun and hopefully someone with better carpentry skills than me can do it justice.
Step 1: Understand the design
and open the file in it. Spin the model round to get a good look at it.
The basis for each component is a 25mm x 30mm section. The real change I made to the design during construction was to cut down the number of threaded rods to 3, however I think in hind sight with a decent set of sash clamps they could be omitted altogether and the top could be just glued.
