Nick writes in via the MAKE forums – “Someone, quite probably our 3 year old Henry, was monkeying with the dishwasher basket (or whatever the heck that part is called) and one of the wheels came loose while the machine was working. I found it partially melted against the heating element of the Dishwasher when I unloaded the machine. I could have just chucked it and accepted that the basket might wobble, or I could have gone through the process of tracking down a replacement if one could be bought without buying the entire assembly. What I chose to do was make a replacement on my Taig lathe.” Link.
