Duct work

["Bill Gilroy" <wmgilroy@gmail.com>]

Not being a tinknocker I have a question on how to make a duct.  This is the
problem I need to solve.  I have a 7" round exhaust duct that has a 3 inch
gap.  The two end do not line up the they are shifted over by about 2 3/4"
inches.  Any ideas how I go about making a pattern that will work in this
situation?  I can wrap it around and screw it in place if need be.
