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.
