I am a new owner of a T4. I have been using the knife jig and the small knife jig. As I use the angle master I find the angle I want is 30 degrees. As I set the guide I cannot get the Knife to sit at the 15 degrees indicated by the angle master. It appears that the length of the adjustment rod is too short to get the knife "flatter" on the wheel. I have watched the video several times and have practiced on a few old knives, but I am not sure what I need to do to insure I am at the right angle.
