Forget the depth guide and catch the back of the blade as high as possible in the clamp. Also don’t try too acute an angle with a very narrow blade as you will hit the top of the vise/clamp with the paddles. Remember an angle of 20 degrees per side is just as sharp as any other angle plus it will take more of a beating than 15 degrees for example.I have done a blade of 5/8ths of an inch width clamped as high as I could get it and it worked fine with an angle of 22 degrees per side…sharp as the dickens.
Cheers and good luck
