Jennifer, don't turn your back on it, it WILL split.Thanks Jim..Allen~ this is the first time I have turned the ebony. It had a small crack to start with so I used ca on it to start. I drilled very slowly and stopped a few times just to let the blank cool down. I added ca several times~ just a drop~ on the crack during turning and sanding and it sealed it nicely with no others occuring...Perhaps beginners luck? lol
