Charlie,
The pinhole tends to become obscure after a few holes, but I just blow the debris away with a can of air. The real drawback to this setup is going out of calibration with horizontal movement of the drill head. It's easy to fix, however; just remove the project box lid, replace the shim and drill a new hole.
