When you are making templates for aluminum or steel sheet, what type of cardboard do you use and where do you get it? In other words, what type of cardboard best mimics the metal characteristics?

A. I use a material called chip board for most of my patterns. It’s very much like the heavy paper they use to make cereal boxes. It’s available from many sources; the last couple of batches I got were from a large commercial printing company. I don’t think they do much printing on chip board, but when they fill up a large box with printed forms they use the chip board to separate layers. It’s thin enough to cut easily with scissors, but heavy enough to hold its shape pretty well. I don’t like to use corrugated cardboard, since it doesn’t bend smoothly, and it’s difficult to cut with a clean edge. CT
