Hi GREENMAN, That is a pretty interesting piece , not seen it's like before , as others have said well photographed , and it is apparent that a lot of time and effort went in to finishing the interior , and I certainly agree with your opinion that if the holes are large then just painting it black is not so good , I rarely turn a piece with such large holes and I usually paint the interior black , as someone said "it is easier to clear shavings and judge thickness " .. this is true .. however tool control and the fragility of the unbalanced work can make it more difficult / skilled so well done and thanks for sharing .... terry ...
