I've been working on it all day. I needed some of my heat bending tricks to get the nice undulating Yew strip.
Once I've added a small waggle brass leading into the brass rods I'll probably dismantle it all, re-finish the base, varnish the major parts and re assemble it. I'll probably give it a light spray of lacquer to stop any discolouration of the brass.
You can see from the reflections, the base isn't too bad, considering it's plywood.
