Oscar & Netters, In the Upolstery world, this is called skeiving (pronounced sky-ving). In fact there are guys that work for some automotive seating suppliers that are truely artisans at this craft. They can skeive foam to shape and you would swear that the foam was created in a mold.
Did you know that you can use ordinary weed-whacker line to create details / "piping" etc. in the covers and under the foam? You can attach the covers to the line (under the foam) with hog-rings. You can also fabricate "spring mats" out of weed whacker line and wire, with the wire spaced approximately 3/8ths apart. Secure the mat with springs to the seat cushion frame. You will need some fairly stiff springs, something like a .5 mean diameter and maybe .078 dia wire something around 1.5 inches long. You could maybe use some drum brake return springs, as they would be pretty close to what you should use. Mount the spring mat in the seat frame centered on the Ischial contact point. (tail bone). I highly recomend the use of a spring mat, as it reduces driver (pilot) and passenger fatigue during long flights by reducing vibrations into the body.

The one I use is one that came with a bread slicing setup, but most any electric knife will work. Scott Cable Jamestown, ND s2cab...@yahoo.com --------------------------------- Yahoo!
