[TheForge] forge blower, dimmers, etc.

[Bruce Freeman]

A squirrel-cage blower might not provide enough pressure for a coal
forge.  A centrifugal blower is better.

Another source for centrifugal blowers is a junked clothes dryer.
Comes with motor, fan and most of the housing - some patching
required.  Remounting the motor may be necessary, as part of the motor
mount may not be separate from the dryer structure.
