I use a "Platten" I made out of 3/4 birch plywood and some adjustable stops that I align and tighten the stock with some adjustable blocks I made out of oak. I tape the end of the stock and tape it. I then use a piece of wood I have cut to the outside curve of the stock to get a straight line to cut depencding on the pitch. I used flat head machine screws on the bottom of the platten and oak to make the adjusters. I use a bandsaw to cut the stock with. I can forward a picture of my platten and dimensions to anyone when I get back from Chicago on the 15th.
