The base mouldings on kneehole desks are invariably quite pronounced, adding bold lines to the ins and outs of the pedestals and kneehole. I stuck the moulding in a couple of suitable lengths of mahogany and then glued and nailed the mouldings to the bottoms of the pedestals.
I then cut out the sixteen brackets for the feet. You wouldn’t believe how much mahogany this many brackets consumes!
The brackets were mitred and glued together in adjacent pairs which were then slathered in glue and rubbed onto the base mouldings.
I split some corner blocks from square pine stock and rubbed the triangular blocks into the corners behind the feet, leaving about 1/8″ protruding beyond the brackets to bear the weight of the desk. Chamfered glue blocks were rubbed against the brackets and base moulding to bolster the feet.
