I should have commented further. Since Lignum Vitae as we know it is a new world wood, it would not have been used in 1350 in Europe. I don't know what would have been used as a bearing, probably just hard wood with the hole made by burning with an iron slightly smaller than the shaft, and the hole worked by the shaft itself.
But I like working with Lignum Vitae, it is just therapeutic turning something so dense, hard, and tight grained. I like boring it, and machining it in thousandhs of an inch, and the finish a good sharp tool gives. There is also something about holding a piece of wood that weight THAT much for such a small piece - it is one of the remarkable anomalies of nature, wood that in so many ways responds like metal. I just like it.
