Noland; we all have our best idea. Here is mine. I dont use dryer duct its
hard to use. I use 4 in flex heat duct with out streaching it out. I flatten
1 inch of one end and crimp the flattened end like a stove pipe and insert
that end into the other end using 5 min epoxi to hold it tight. After it is
hard I use 2 small 4 in pie pans pop rivited together like a tire rim as a
center with a 1/4 in hole in the center so I can bolt it to my coil with a 3
in brass toilet bolt. Its all aluminum, its easy, its quick.
