Step 2 The Duct

Next we will prepare the duct.

Wrap a piece of paper around the stove pipe, line up one edge even all the way around. Then grab the sharpie and mark a line all the way around the duct. This needs to be about a foot from the sharp edge of the duct (to make about a nine inch to one foot long duct)

Then pop open the seam of the duct, take your snips out, and cut it along the line.

Next we have to deform it into a rectangular shape, this is alot easier than it looks.

Take the duct in your hand and press it against a hard flat surface (your table) it will form 2 seams approximately equidistant from each other

Then grab the duct about an inch or two from the one of the creases and press it against the table again making another crease.

Now press the wide flat part of the duct against the table, holding it approximately the same distance as the other shorter face and bend in the last crease.
