ASSEMBLED entirely from discarded
materials, this forge consists essen-
tially of an old vacuum-cleaner motor and
blower, and a cast-iron sink. The dimen-
sions given may be altered to suit the
material at hand. The air blast from the
blower is divided, half of the air being di-
verted up the stack to keep the shop clear
of smoke, the Y-fitting for this purpose
having been taken from a Ford
V-8
ex-
haustpipe. The original strainer in the
sink serves as the tuyere iron, and a 1%-in.
street elbow connects the sink with the
draft pipe. The cast iron ring that origi-
nally held the lead pipe to the sink outlet
canbe used to hold the street elbow if it
is enlarged slightly. By using wingnuts on
the bolts, it
is
an easy matter to remove
the elbow for cleaning out ashes and cin-
ders.

completes the forge. The switch

and gives three speeds. It is a
good idea to line the inside of the
sink with fire clay or some other
refractory material.
