I'm in the process of reskinning my cracked, non-prepunched rudder. I've built a set of V-blocks, but I'm missing the drawings (SK1 and SK-2) that show the distance between the V-blocks when on the table. Can anyone provide this measurement? Or should I just move the blocks so that the trailing edge of the skin is parallel to the table top? Finally, I'm missing most all of the other drawings for the rudder. Can anyone poke holes in the theory that I should be able to take all of the necessary measurements from the existing skin? Sadly, Vans doesn't have the old drawings available.
