Here's the video of the garage heater screaming at me last Tuesday.  
Sunday, November 25, 2012 - The heater started making weird noises a couple of weeks ago, but Brian thought he'd fixed it.  It worked for a while, then when I heard this horrible noise, I knew it was over.  Apparently, the motor is shot.
     Bob just got an email that the new heater has been shipped.  Hopefully, it will be installed this week.  It has been an interesting adventure trying to keep the garage from freezing.  Right now, it's 56 degrees out there.  Oh boy, a heat wave.  brrrr ya later, djb
