    Default Bowl jaw alternatives for finishing bottoms

    Hi folks,

    Just turned and finished the top half of a bowl, and went to reverse it onto my bowl jaws only to discover while the bowl has respectable clearance over the bed of the lathe, the jaws project far enough past the bowl that it can't turn.

    Are there good alternative techniques for cleaning up the bottom of a bowl? The finish on the top half came up pretty nicely, so I am not really keen to try gluing it up if I can avoid it.

    I pretty much just need to get rid of a waste block glued to the bottom, finalise the shape, and then sand and finish.

    Cheers,

    Danny

    Leading contender from research so far is to make a donut chuck!

    Use a jamb chuck
    Mount a disc a bit bigger than your bowl on your chuck , true it up if necessary . Mount your bowl on this with the tailstock in the centre of the tennon and turn away as much of the tennon as you can, then saw off the nub .Mount a Jacobs chuck on the headstock with a sanding cone and sand through the grits while just holding the bowl in your hands

    A jamb chuck seems to have done the trick without taking much time. Now just need to sort out the nub from the tailstock.

    I use a face plate jam chuck with tail center to keep the bowl in place, turn off the bottom, sand, take faceplate and bowl off lathe and pare off the nub with a bench chisel, carefully hand sand or use a small drill mounted disk, finish sand and finish.
    So much timber, so little time.

    So the finish on the very bottom isn't as nice as the bits finished on the lathe, but I'm still happy with how it came out - thanks for the pointers everyone!



    I think I'm going to call it a transatlantic bowl - american cherry and english sycamore.

    Next time finish the foot when you turn it the first time.

    Will require a range of jaws.
    Stay sharp and stay safe!
