Bob, I agree that the best and most accurate way to make this trim is in a roll former. Once the dies are made and you can get a siding or roofing manufacturer to agree to make it you are in business. You can buy slit rolled product from a mill in coil form. The siding manufacturer could set up their machine load the coil run it through a flattener and produce one coil lengths worth of product. The problem would be the ends and being able to accurately cut the fluted material without distorting it. With the amount of buses out there I would think there is a market for the trim.
The 20 gauge material that I used in the short section wanted to flop around a good bit. For long pieces this could create a real problem and would probably need some type of hold down. I don't have a feed or discharge table that would be needed for both the pullmax and the bead roller to produce the trim. This would be an expensive project because of the amount of cost in setting up the equipment. The roll former is the way to go especially if the gauge of the metal is thinner than 20 gauge.
