Ian Kirby demonstrating a 90° shooting board, which works on the same principles as the questioner's 45° shooting board.

\ Without seeing the i * drawing of the miter shooting board, it's impossible for me to be specific about its design and your interpretation of it. However, your phrase "without cutting into the jig itself' prompts me to emphasize that these things are not jigs. A jig is a device which produces the exact same result no matter who uses it. Your shooting board could be perfectly made, but if the plane blade was not sharpened straight, if it was incorrectly set, if the sole was not square to the side of the plane, or if you pressed

harder on one side of the plane than the other while making the cut, then the outcome would be affected. Moreover, this short list doesn't cover all the variables that you or I could introduce.

Now to your problem. To prevent the blade from contacting the 45° holding block on top of the board, the rabbet that the plane runs in is not at 90°. The edge of the top board is made to an angle of 10°-15°. In this way the

closed portion of the throat — the slot that the blade projects through — rides on the bottom portion of the angled rabbet and the blade misses the holding block on top.
