Assuming you are drilling something soft. Ie. Eva or cork rings. Take your piece and drill your two inches. Stp the machine. Loosen the chuck. Crank down the spindle so it travels are far as its going to go. It then stops. Hold your drill bit (youve traveled all the way down). Now while holding your bit raise your travel your remaining half inch. Tighten your chuck. If youre careful you shouldn't move your piece. And you've just given yourself that little bit extra you needed.
