Ebony 4″ x 4″ x 2″
when you work ebony it needs to be rough worked and never left on the lathe or it will crack
The best way to work this wood is to Rough turn, Then put the piece of wood into a bag with its shavings and then air tight the bag. Then with a pen make a few holes and keep in a cool place.
This will allow the ebony to dry out slowly. After a couple of weeks go back to the piece and finish.
