Troy there is a simple and easy way to get that angled drill hole. Cut a guide block at the degree of slope that you are wanting to use. For instance if you want to use a 23 degree angle then cut one and then use a hand drill and lay the drill bit along the incline that you just cut and drill your hole, no need for a drill press with a tilting table. Just a block of wood cut at an angle. Just something I have found that works well.
