I'm curious, how did you actually shape the wooden last you used to form
the concave dish portion? By hand? On some sort of wood lathe? Other?

I first made a flat template from a sheet of aluminum. Just carved away while
periodically testing it's shape with the template.

I just spun it round, and used a couple of wood planers, took a few hours and a
lot of work and many blade sharpenings later it was basically finished.

I finished it off on a normal metal lathe that could hold a 60cm dia piece of
wood, used a chisel in hand, just the last 1/4".

It's been many years since I last did anything like this (I won't say how many
), was at school when I last did any lathe work.

Was fun though.
