[TheForge] side draft hoods

[Peter Hirst]

Thanks for the tip on the Anvilfire drawings.

Interesting that the notes for Lester's Supersucker are identical to those 
for the big  side draft units.  Lester's makes more sense to me than the 
bigger units, especially if you ignore the notes.  Seems to me one of the 
big advantages of Lester's is that it eliminates the "expansion chamber", 
which is something I don't understand anyway.  What exactly is supposedly 
"expanding", anyway?  Seems more like it would serve as a cooling and 
contracting chamber, and work counter to the stack effect.  Lester's, on the 
other hand appears to concentrate the stack effect right at the fire. Best 
side draft unit I ever saw in operation was just a 12x12 opening in the side 
of a 12" clay tile flue in a  brick chimney. No chamber, no smoke shelf, 
nothin but an opening.  The bottom edge was about 6" above and 6" to the 
side of the top lip of the firepot. smoke and flame blew flat horizontal 
into the bottom 4" or so of the opening.

Lester's Supersucker is the closest thing I've seen to that brick chimney 
flue, and  I've aleady started drawings to adapt it to my forge, which 
currently has a big old wide hood that draws lousy.
