I found the back I prepared long ago (not a mean feat since the bench is cluttered) and cut the shape with my Knew Concept saw. That saw is a bit weird. Sometimes it works and I love it, other times it is hard to tune and keeps botching up the cuts.
The back is jointed so I took one of the offcuts and made a cross banding strip. It’s segmented to fit with the braces. In the pic I’m chamfering the edges with my miniature shoulder plane.
And on it goes. Usually I use the go-bar deck to put some extra pressure on some spots but yesterday I fitted some wedges here and there to assure an even bead of squeeze out in the joint.
This morning I took it out and it has a really nice dark tap tone now, it all sort of comes together when the back goes on.
