I had just finished my last instructable http://www.instructables.com/id/Strip-Table-in-oak-and-walnut/ and so decided another table was too much and I had no where to put it.
The design uses the timber to create a form not usually seen in timber it is more like a plastic in that the bowl element appears vac formed in to the top surface of the piece.
I have attached a sketchup model of the sideboard. There are 2 models a visual model and an exploded model where each component can be examined seperately.
If you down load the models have a good look at them to see how the design works.

Step 1: Turn the bowl
The turning for the bowl has too difficult elements to it - the first is that you will be leaving a square edge - the second is that you will be turning both sides of the bowl seperately.
A lathe and a bandsaw. ( a flat bed circular saw is useful but not essential) a sander and some sash clamps.
I have started with turning the bowl as I think it is the hardest part of the build and if you cant get it right it will save wasting time and materials on the rest of it.
Be careful you are turning a large piece of wood. Set the lathe to the slowest speed. take tiny nibbles out of the surface until you are down to the round. Dont catch your knuckles on the spinning square edge it really hurts!
You will need to glue up a block of timber 260mm x 260mm x 80mm. Mine was made from 13no 260mm x 80mm x 20mm strips. let it dry overnight check the instructions on the glue to see how long it needs to cure. I have only had one piece of wood ever come apart on me it had its own blast radius and I was wearing a full face mask - it was glued together in a rush need I say more...
Make 2 card templates one for the inside of the bowl and one for the outside of the bowl these will allow you to measure the curves you are turning. see pic
Rough out the inside of the bowl and then using your card template you can copy the profile onto the bowl surface by turning a bit and then offering up the template then turning a bit more.
Once you have turned the inside of the bowl remove it from the mounting plate. You will need to make up a mount ( i used some scrap mdf) to re attach the mounting plate to the turned side of your block (see pic)
Turn the other side, this is where you will really need your template it will stop you going all the way through the bowl.
Take your time and sand both sides of the bowl on the lathe as its so much easier than taking it off and trying to sand it by hand.
Ok so after turning the first bowl (shown in the picture) I decided it didnt fit with the wider strips of the rest of the design so I started again and glued up a new block from 4 pieces 260mm x 65mm x 80mm to make a block 260 x 260 x 80
