When I was turning my yew bowl, I found the two halves of a turned box that I had started making sometime last year.
Since I was "in the zone", I chucked these well seasoned pieces, one after the other, and turned them true. Then I formed the lips for the press fit joint, mounted the closed box between centres to perfect the flowing curve, used a jam chuck to allow the top and bottom to be completed, and finished the box with tung oil and wax.
I don't consider myself experienced enough to produce an instructional video on turning just yet, but I'm trying to get plenty of regular practice, so maybe in the future!
