Following a request from Bloozoo2, here is a bit more info on the wood I used.
B&Q call it Furniture Board. They used to call it Conti-Board.
It is laminated/veneered chipboard as shown on
this site and is the same stuff that most self-assembly furniture is made from, as are the Juwel stands (hence my choice).
It is available in many colours including black, white, beech, mahogany.
15mm thick is enough to make screwing together easy.
I made a first attempt (call it a prototype) with MDF, but MDF is difficult to screw into, makes a lot of dust when cutting and drilling and needs finishing on the inside and outside. It didn't paint well either, but that might have been me. The Furniture Board needs varnishing on the inside, but the outside is already done and matches the stand straight away. Most commercially available wooden hoods I have seen are also made from this.
I'm sure that a well made and finished pine (or other real wood) hood would look much nicer, but for ease of build I don't think you can beat this stuff.
