Your stack base is a wonderful work-around. And, once figured out, it's wonderfully simple. Your finished piece looks great! Thanks for sharing your experience.
Thanks for the kind words (Llyn, Bill, Poys and Scott). I start with a brass disk of oversize diameter/thickness and soft solder it to a brass bar. In the next step I turn it down to the correct diameter and length (thickness). I then use an Excel table, indexed by 0.002" (0.05mm) in x and start turning from the outside to a diameter (or travel) given by the table. Due to the setting of the x-axis you don't get lost in the table. Each cut only removes 0.002". You get very fine steps, which can be easily filed/sanded.This is how it looks like after turning:Henner,
this is a work of art, Beautiful Craftsmanship! And yes please do tell how you machined the smokebox door.
