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.
Step 2: Select your wood
I think it would work with scrap wood or even thick ply as long as you have the right equipment to regularise it.
For example 22mm ply cut into 30mm strips would probably give a great surface effect to the finished table.
