The legs on this cabinet are cut twice from one square blank, and the offcuts from the first cut are needed for the second.
A cabriole leg curves in two planes at once - it sweeps forward at the knee and back at the ankle, and it does the same thing when seen from the side. You cannot saw that shape out of a flat board. It is cut from a square section of timber with the profile marked on two adjacent faces.
The first cut follows the shape on one face. The moment it is made, the blank is no longer square, and the profile drawn on the second face is now floating in mid-air where the waste used to be. So the offcuts are not discarded - they are taped straight back onto the blank, restoring the square, and the second cut is made through the reassembled block. Only then does the waste come away, and the leg emerges curved in both directions.
Shaping, carving the knee and finishing the pad foot all follow by hand. Four legs are worked stage by stage together, so no one leg gets ahead of the set.
