High-speed milling is hot, but bronze casting is hotter, literally at least. For this week's production methods vid we rock it old-school with two clips of lost-wax casting, an ancient method still in use today to make bronze statues and, my neighbor's kid insists, parts of the iPhone. (He's five, so he could be wrong.)
The first clip shows the process on an industrial scale. If you already know how it's done, pre-load the clip and go get yourself a coffee--you can skip the first seven minutes and get to the part we really want to see, which is Molten Hot M-A-G-M-A.
This second, shorter clip shows a Gainesville artist doing her own batches and it's inexplicably scored with the type of piano-and-flute music they play at medieval festivals, so watch at your own risk.
