Just over 12 years ago, I bought a work bench from Travis Perkins. I don't think it cost much. I used it for the occasional DIY job when we lived in a house. It lived outside (it was only a little house) unprotected from the elements. It came with us to France and still lived outside. The leg braces broke a couple of years ago, but nothing that couldn't be fixed with a bit of rope. Sadly, at the end of last year, it died.
I looked at the work benches in my local DIY place and was STUNNED by the prices. Not just that, but none of the benches on offer had wooden worktops (my cheap old one did - which is how it survived for so long). Fortunately, my dad had an almost new leading-brand work bench in his garage which he let me scrounge. I tried to look after it, but eventually it found its way outside for a few days. I also did some round-wood work with it, which is quite normal for us, but which immediately demolished the pressboard worktop. Look:
Absolute crap. Almost certainly designed to fall apart*. For the price it probably was, scandalous.
Fortunately, I had some pieces of chestnut lying around from a failed kitchen cupboard project and knocked up a new worktop in a couple of hours.
I had to do this because I was just about to go to work on the project1p solar shower. And I hope you'll agree, if you're going to work on a solar shower that's been in the making for a Very Long Time and has cost an Eye-wateringly Large Amount of Money, you're going to need a decent work bench.
More on this, later.
*(For more on designed obsolescence, I strongly recommend you watch Pyramids of Waste aka The Lightbulb Conspiracy (2010). Contains some very surprising information and tells you why that leading-brand printer isn't working any more.)
