This is the first thing I've made from black wattle, which is pretty much the Smith or Jones of woodturning timber in Darwin, i..e. everyone uses it because there's plenty available.
It's also a very fine timber for the purpose, and is probably the best local turning timber, taking into account colour, grain, ease of turning, and quality of finish possible.
Which is pretty funny really, because whenever a householder finds a seedling black wattle in their garden, they say "Another bloody black wattle. rip it our before it takes the place over".
The cup, chalice, call it what you will, falls a bit short of perfection. This is normal for me.
I think the holes in the base might have been a mistake, but the idea seemed good at the time.
all the best
