First ignore George, then second glue a waste block on the back,then turn the front,then reverse turn it,a piece of cloth over the jaws and tailstock brought up to waste block to sandwich it in place,then you can gently take small cuts to do the reverse and turn off/part the waste block off,should make some interesting small plates/platters especialy if you can keep some of the bark on.I hope that is helpful to you,regards,
Eric.
