A tip for the success of your work: Lignum vitae, like almost all very hard and dense types of wood tends to crack on endgrain surfaces in dry and warm rooms with low air moisture values; you must expect finest cracks to form during processing. Please do not expose the wood to sudden and strong temperature and humidity changes and protect the end grain with wax or a thin coat of white glue.
