Cassetta frame w Veneer

[Junglewalker]

Has anyone made a frame like this delicious item from the National Gallery?
Would the outer moulding ideally sit over the edge of the central flat frieze veneer?
Could one make a closer imitation of the style of frame than for e.g. Rose & Hollis A169?

That is indeed a beautiful frame. If you are going to try anything similar, then R&h A169 is the closest you'll get. I would however glue one of their thin flat sections to the outside wall, or even one of their shaped slips. Have the facing edge drop about 1cm below the top of the outside edge and round that a bit with some sandpaper. This will give the profile a bit more "presence".
For the veneer, choose burr walnut or elm and cut into strips to fit the cassetta. Glue the veneer onto some kraft paper using contact adhesive. When that's set, break and crack the veneer. Now glue the veneer strips into the casseta, again using the contact adhesive.
The veneer will need cleaned or sanded with various grades of sandpaper wrapped around a block of wood to fit into the cassetta.
All the rest is down to wood finishing and some gilding and that's a whole story in itself.

I've just made one in my shed. Not to be veneered, just painted.

I do them frequently. It's a versatile way of making frames as all you need is a flat bit
with complementary mouldings either side. You can vary the proportions by simply cutting
the panel down. I use mainly three R&H flat mouldings and cut them 'upside down'. That forms
a shelf that the inner moulding neatly locates against. You can shim it to get the right hight.
The outer just fits over. If I were doing it I would make the carcass and lay the veneer in the
channel rather than having it tucked under the outer moulding.

I always think a nice touch on a veneered casseta frame like that is that it is obvious that the veneer from the shape of the pieces of veneer that it has been laid after the frame has been made.

The Courtauld rather than the National Gallery, I believe?
