This seems to have worked out ok. I am still cleaning up excess glue. The top edge of the endclasp is planed flush with the rim of the lute body – and both ends shaped so that they can eventually merge with the curves of the soundboard.
Next task is, indeed, construction of a soundboard. I plan to make one from Huon Pine; another from King William Pine; thereafter, cut a Rose decoration in each – and then form a judgement, or perhaps toss a coin: whatever seems appropriate….
