Half Height Helper with Carbide insert

“Good joinery is done with a pencil, great joinery is done with a marking knife” -Jonathan Katz Moses. This addition to the Half Height Helper will let you add a carbide insert to use for scoring your material. The issue I have with the microjig version is that you have to use a pencil to mark your piece which will introduce error. Now you can use the front of the half height gauge to mark your project precisely.
