[TheForge] Blower possibilities

[Grover.Richardson at gtri.gatech.edu]

If you make a baffle box to snub the sound, the sound level will be much better. Also, it is possible that you don't need it running full all the time, so a lamp dimmer on the blower motor would keep the noise low.

What I did for a while is I had two lamp dimmers.  When I put my metal in the fire, I laid my hammer on a metal plate.  The weight on the metal plate closed a micro switch and selected the high speed fan.  When I removed the metal from the fire, I picked up my hammer.  Removing weight from the plate caused the switch to select the "keep alive" fan control.  While it is easy for an electric/electronic type fella to just use one lamp dimmer and two controls, this would require someone to take a lamp dimmer apart and to have a small clue as to how things work<G>.  Easier to just use two.

All the Best
