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. A ~iece

of flexible tubing run up the

hood from the Y-connection and strapped

to it completes this part of the job. The

SINK 18~x30

hood itself is made from a single

,> x

piece of sheet metal. The addition

of brackets and a "douse" tank

completes the forge. The switch

for controlling the motor is pro-

tected with a sheet-metal cover

and gives three speeds. It is a

good idea to line the inside of the

sink with fire clay or some other

refractory material.

Tabs around the smoke opening of the hood

are drilled for screws to attach a ring and

collar assembly, which takes a smokepipe
