Good progress was made yesterday; I cut out all the pieces and dry fit them to check fit and to see if the folding mechanism worked. It did, and after all all the difficulty with the curvy legs, those look fine now. The only parts missing are the two stretchers at the lower part of the legs and the swivel piece that locks the top in place. Everything will be taken apart again for sanding.
Walnut is a pleasant wood to work with and I'm looking forward to how it will look when the finish is put on.
