An alternative plan is to gouge out in a flat block a bed in which to rest the back, but it is a troublesome piece of work, and the writer has found the pad entirely satisfactory in use. A diagram of the back with guides gouged out is shown by Fig. 26.
5The whole of the inside must now be gouged out to the same thickness, taking out the wood between these guide grooves first of all, and working the edges last, leaving the flat places marked for blocks untouched.
