AS BY LUCK SAW THIS AT A TREE FELLERS YARD. GOT IT FOR FREE,A SILVER BIRCH LOG.AS HAD SOME COPPER STRIPS SPARE,TURNED THIS AND INLAID IT WITH COPPER STRIP.. NEEDS TO BE NOW VARNISHED. A BOWL FOR EVERY DAY USE..PLUS IT WAS TURNED USING MY FILES WHICH I GROUND TO TURNING CHISELS. AND IT WAS TURNED ON FACE PLATE USING THE DOG TEETH TO HOLD IT, AS I SAID BEFORE EVERYTHING IS POSSIBLE IF YOU PUT YOUR MIND TO IT??
