Figs. '7 to 10, inclusive, illustrate preferred steps
in the method of forming the sinks in accordance
with the invention from a single sheet metal
blank. In fabricating the double drainboard sink 66
of Fig. 1 a single sheet metal blank ‘I0 is placed ‘
in a suitable press and the central portion is
preliminarily drawn to provide the sub-basin 3|,
as illustrated in Fig. '7, this being accomplished
by a suitably shaped dies. In a succeeding'oper
ation the blank is operated upon in suitable dies
to form simultaneously the main basin 30 and
the drain beads 88in the bottom 32 thereof, as
illustrated in Fig. 8. In the same or succeeding
operationsthe sub-
