Many years ago, I designed and built this potting table. It is narrow enough to fit down the path into the garden, and has a couple of wooden wheels. I also put in a couple of hatches on the top, and some lugs to hold a removable mezzanine level. The idea was that the hatch could come off and a bag of potting mix or a bucket of water could be put in. With one thing and another, I never got that part done.
It was a pretty experimental effort, and there are a lot of things I did wrong. But all in all, it has been a pretty useful table, and has held together a lot longer than I thought it would. A lot of it is not treated timber, so surprising it has not rotted out in places.
Now I have a prototype, I really should get onto the final version.
