David from here it is impossible to know the timber characteristics of your particular blank but this timber is incredible it finishes so well as you turn and you detect unusual lifting etc go for the sandpaper as you finalise the shape I have black and northern, southern etc versions would like to in time do a sample of each with before and after, well worth the effort mate, salvaged a wardrobe years ago it is a great furniture timber was almost wiped out by overuse here over the early years. It can in larger sizes bring out a terrible rash including skin breakouts a world famous hat maker visiting here turned a 40 kg block broke out in blisters, it has never even made me scratch . I give you the illustration of the hat it was turned wringing wet a full Western American Stetson style only mm,s thick no chipping or breakouts. whenever I have turned the Kimberly cousin Beefwood the forum rally enjoy that as well. Take care mate.
