Step 4The Adapter
This is the hard step.
In this step we have to adapt the blower to the duct size.
This is the step that will require you to adapt to the blower you picked out, mine was an A/C Fan from an 86 honda crx. :)
The way that I made the adapter, I took the blower and sat it on my sheet metal and tried to trace around the outlet (you can see how well that went). Then I trace inside that around my duct.
Then I used a straight edge to draw in some flaps on the inside (duct) and the outside (blower), in order to rivet the adapter to the duct and tape it to the blower.

hmm, perhaps an alternative would be to use a dremel tool with a cutoff wheel attachment, then deburr and sand the edges, or use tin snips if you have a fine touch. i dunno though; just putting my 2 cents in

Some old microwaves have nice squirrel cage fans. They run right from the AC line.

An alternative to that adapter stuff is to just cut the seams of the duct at one end (about 2") and just bend them at 90 degree angles away from the center of the duct, like flaps. (front view [] > {[]})
