Creative design The lid insert being off center adds interest.
Yes, I was going to ask if you used a Rose Engine lathe.
Also, interesting with the birch/ebony box.... is there a birch insert in the ebony or is the ebony a sleeve over the birch ?
Sorry for the late reply.
The body is a Philippine ebony pipe resting on a Karelia birch base and the interior is a pot of ceylon lemon tree which protrudes and receives the thread .
The lathe is a Vicmarc VL 300 on the bench of which is adapted a cross table equipped with a portable Kress milling machine .
