I've seen a few pictures of high-end instruments with fancy wooden end plates, where it looks like the centre portion is made from laminated wood with a pretty veneer, and there is a border around it (that looks at least as wide as the action box walls) made from solid wood with a moulded profile.
The Wheatstone Aeola that conzertino recently posted for sale is a particularly gorgeous example:

Does anyone know how these boards are constructed? Is the border made from eight mitred strips glued to the outside of a centre board that was previously laminated and cut to shape? If so is there a simple edge butt joint between the border and the core, or are they overlapped to increase the strength?

These ends are made from a single piece of laminate, with the edges formed on a router. The only difference is that the edges are finished in black French polish. When restoring them I usually mask the frames and use a brush to apply black stain to the edges, then apply clear French polish over the whole end with a traditional pad or 'rubber'.

I see, thanks. That's certainly simpler than I imagined.

Here's another example (unfortunately not very good pictures) where it definitely looks like it's fabricated from a separate core and border:

I put a separate border around the outside, takes about an hour per end. I have also seen a Wheatstone that did it the same way. I overlap both the "core" and the action box frame.

I used to do it like that, exactly like that, but there are a lot of factors to get right at once. These pics probably explain my current method better than a lot of typing. The parts are all from the reject bin so they don't fit together, in the first pic one part is from an octo, the other from a hexagon.

a rather good way I have seen this done is by glueing up a laminate of say 4 layers of thin wood veneer, the bottom 3 being dark in colour (black tulipwood veneer apparently works well) and the top layer being brighter (classically amboyna or some other decorative wood) then the router is passed round the edge to form the moulding which will reveal the dark lower woods, its rather effective I have seen at least one other concertina maker do it this way.
