I've been doing quite a bit of electronics work lately, and decided that a permanent work area was required where I can leave the gear set up and can work AdHoc without have to haul everything out everytime I needed to work on something. I looked around the place to see if there was something I could buy, and most were pretty expensive, so I decided I may as well build one. So, I decided on a few basic parameters to guide the design : 1. Size - 2400 x 800 was decided for the top area. I wanted it to be a height you could work at either standing, or seated on a tall stool, so I decided the top should be at least 950mm high. 2. Storage - I wanted underbench shelving, but I also wanted to be able to sit right up to the bench, so the shelving had to set back. 3. Backing - I wanted to have a backing board to stop stuff falling off the back of the bench, and also to which I could mount powerpoints/powerboards. 4. Steel frame I then set about drawing it up in Solidworks : I've used 25 x 25 x 1.6 for most of the frame, with 50 x 25 x 1.6 around the top - this spreads the load across the front of the bench to the outside legs (since the centre leg is set back), and also part of the weight of the shelves effectively hanging off it - again spreading the weight to the outside legs. Should be strong.
