Wow its now 2023 and the project and process is attracting a little attention by  members here.
Its something I  just made as a learning aspect of wood work and never built a Curved cabinet.
The door I made has been disposed off in the give aways  when I have had a clean out.
However the jigs  from Les's tutorial and some fabricated parts still exist  with me today
  The Les Hastings tutorial for producing it is actually within Lumberjocks.
I did contact les and he is now enjoying retirement but took the time to tell me where the tutorials lie.

Here is the link to the Les Hastings tutorial
