You will notice that the head and the top of the door are curved, this made the whole door a joy to make (I will forget about lugging it about, though I doubt my back will).
You can see on the back how I have some very slightly raised bearers, how will they hold anything I hear you ask.
The answer is, I used large sliding dovetails.
I'm going to fit tomorrow, so will update with finished pictures then.
Thanks for looking.
