A chunk of Red Iron Bark was the victim.
This started out as an off cut from No 2 Son's bench seat
The table saw process :-
I marked it all up and determined how I would go about making a one piece lid.
the first cut was to remove the material around the handle.
I set the saw blade height to 60 mm This gave eight blocks, 4x 60mm x 60mm from all four corners 2x 60mm x 85mm either side of of the handle, and 2 x 60mm x 45mm from each end of the handle.
I was then left with a Block in the center (soon to become the handle) 85mm x 45 mm
I the set the blade up to 66mm and carefully cut out the recess to be able to hold the handle.
This recess is about 10mm deep. (see picture 2)
next I cut a recess all around the lid to fit the box this was 10mm x 10mm then trimmed to support a reasonably tight fit. (see photo 5) this was all initially done on the table saw to produce the raw result
then a little saw kerf removal with a router bit and rounding over of the edges completed the production of the lid.
it was then sanded and finally polished to produce the finished result (see photo 4)
I hope that explains the process more accurately.
