Stephen,
That is a damned fine piece of work!
In the picture of the unfinished mouldings, do I detect pocket hole screw holes. ( the pics arrived in the reverse order to their descriptions ((confused me slightly)), however, it's pic 2, as it's the middle of 3) or is this simply an effect of cutting, possibly across a knot in the wood (three distinct marks to the base of left strip)? if it was pocket hole tech, did you dowel the holes ion the final fixing? I was looking for the 'tell tale' round dowel marks in the final pic, but didn't note any!
Fantastic work! I loved the finished product. (excuse my cross posting, friends, I hope it's permitted?)
