I nipped a small locust log from John Kauer and turned an end grain vase out of it using a stainless steel insert.
Shaped the outside a little, and drilled a hole, and turned out the inside in a taper (using a Oneway "Termite" ring tool) to accomodate the stainless steel insert,
Made a tapered jam chuck from a piece of firewood to hold the vase while I turned off the tenon on the base.
