Jack and I machined the first one a few years ago- and as good as it looks in the photos, it looks even beter in real life. I want one… or more than one. They can be made relatively inexpensively with a CNC lathe, as aluminum is easy to work with, and it’s relatively easy to cut down the stepped top from a cylinder. hollowing it out is also relativley easy with a CNC mill.
Next up I’d go for a conical mount-instead of the stepped. it might not make as good swarf, but the concept can still be applied, especially with a CNC or using a fancier lathe.
