I looked in my library and I only have three books on sheet
metal. One is the Fournier book that I got from Lindsey.
Another is a MAP publication (one of the Model Engineer series of
handbooks) and a third is a 1952 soft bound book by Smith. The
Smith and MAP books are telling the same story, while Fournier is
mostly about beating auto panels.

If you are trying to make cyclones, then you should be able to
find resources on the www. The sheet metal part is pretty easy
acording to the MAP book, which says cones are the easiest to lay
out and the most often required shape. Any good math reference
book having mensuration formulae should give you the formulas
needed for the layout. That is why I said that MS Excel can
calculate and print what you may need.
