The Sportsman kit included a sheet of .063 2024 T6 aluminum. We marked the sheet with many vertical lines and then used them to mark the curve of the top of the panel so it would bit the fiberglass glareshield. Interesting project. Then Brutus cut the panel out on a new RIGID band saw Stratford bought. Through the years of building we used the band saw many, many times, with both fine toot and coarse tooth blades, bot narrow and wide.
