G'day p.t.c.

I always start a box between centers. Turn a spigot (tenon)
on each end to grip with a chuck or glue into a jam chuck. All turning (inside hollowing and outside final turning) is done by gripping the spigot. Since the spigots are parted off last and those areas hand sanded the shape of the box is not important. Actually, one of the ends can be finished on the lathe with the help of a couple of wraps of painter's tape (masking tape) around the joint where the lid joins the bottom.

Hollow Easter eggs can be tuned the same way. You may find the egg shape to be a little easier than a sphere for the first few tries.

I hope that this helps.

And then there's the conventional way ...
Using a scroll chuck or a cup chuck, turn the lid first. You turn the inside of the lid and the rim of the lid, and start its outside, then part it off. Then begin the interior of the bottom, and the rim of the bottom. Turn the rim so that it serves as a jam chuck for the lid, and jam the lid on. Then finish the lid. Remove the lid and finish the rim of the bottom so that the lid fits snugly but not tightly. Then finish the interior of the bottom and start the external shape. Remove the bottom and make up a jam chuck so that the bottom can be reversed. Then finish the bottom. Em nau!
