When we have got it roughly round we mount a jacobs chuck on the tailstock and drill another 
45mm hole approx 10mm deep so we can turn the box around when we have finished the sides and 
bottom:

 When we have done this
we then use a 3.5mm drill
bit to drill just into the 
bottom of the drawer section.

This is to mark a centre
point on the bottom of
the drawer for later

We can then finish turning and sanding and adding any finish to the sides and bottom of the box.

We actually did final finishing on a polishing mop system rather than on the lathe as there are some 
parts that cannot be reached whilst mounted on the lathe.

The project can then be inverted and the top finished in the same way.

Do make sure your workpiece has as much support at both ends when turning as possible:

When you are happy with
the outside, the screw can be
taken out and the drawer
removed.

Here you will see the small
hole we made with the 3.5mm
drill bit in the bottom of the 
drawer section: 

Now we can look at hollowing out the drawer.
