Mike,



The length of the cylindrical section is 24 inches.  The conical section is
9 inches long.

The dome was made from a Kmart mixing bowl.  Some of it  is less than 0.032
inches thick but has held up so far.

The cylindrical section was made by a local sheet metal shop with a stove
pipe joint that also has been tack welded in a few places.

I made the conical section, inside parts, heat shield, and mount from the
same sheet material as the cylindrical section.  The joint in the conical
section is similar to the stove pipe joint and is also tack welded.
