As with the mirror frame stock I have previously written about, the stock for this mirror consists of blocks of walnut glued – at 90° – onto a core which in this instance is also walnut. Cushion moulding (so named because of its obvious resemblance to a well-stuffed feather cushion) is simplicity itself to create.
Once the frame stock was squared-up, I planed the glass rebate and shaped the cushion moulding with a hollow moulding plane. Even in the absence of a suitably sized hollow moulding plane, the profile could easily be made using virtually any flat plane followed by judicial scraping.
The frame stock was simply mitred at the required lengths, and glued together. Strips of veneer were glued into saw cuts made through each mitre to strengthen the joints. The frets will ultimately hide these splines.
I cut some 5/64″ (2mm) thick veneer from an attractively figured piece of walnut which I then glued, book-matched, onto a prepared pine ground.
I glued the frets onto the frame and then bolstered them with split, triangular pine glue blocks which were rubbed onto the frame and the back of the frets. Finally, the edges of the frets were back-bevelled to reduce their visibility from the front.
