Once the rim
is turned to the thickness I want and is consistent all the way around I can
start to remove the centre material.

Photo #13: Bowl Hollowed Photo #14: Dressing the edges
I cut a
rabbet for the lid to sit in and then hollow the bowl just like any other
bowl. The lid rabbet will need to be
touched up a bit to bring it back to round after the bowl is sanded and
finished, because the shape will “relax” a bit and the bowl will go very slightly
oval. I sand and finish the inside of
the bowl, then I dress the edges to remove any milling marks or minor
chip-out. This is my old lathe, which
did not have a locking headstock, so I blocked up from the lathe bed to keep
the piece from moving while I was working the edges.

Once all four
edges are cleaned up I re-true the lid rabbet, apply another coat of finish,
and remove the piece from the lathe.
The bowl bottom is complete.

The lid starts out just the way the bottom did. I find the centre of the blank and bore a 1” hole for the chuck jaws. I could rough these round on the band saw, but I find it just as easy to turn them round. Once the lid has been roughed out I lay out the chucking recess on the top face. This hole will perform double duty as both the chucking recess and the mortise for the knob tenon.
