We just got back from my wife's brothers services. I was called at the last minute because the family decided to have me turn a burial urn. There was no way to do it with green wood so decided to make a staved piece out of kiln dried 1 X walnut. They called me to ask on Sunday the 5th and the service was Saturday the 11th. So this one was quick but made with a lot of thought and love. It is walnut. The inside diameter is 7 1/4" and it is 8" tall. Probably could have went slightly smaller but didn't want to take a chance since we were driving 200 miles. Anyway it has a lacquer finish after being sanded to 600 grit and I burned a band on the top and bottom. The other problem I had is I had no wood that would take threads well and definitely the walnut wouldn't. So improvised and use pvc threads. Wish I had went with black abs now. I wish I would have had more time but they thought it was brilliant and all loved the piece.
