Tsk, tsk, tsk - c'mon guys - a bit of imagination here eh? . A hardwood board with a dado groove cut the same width as the metal and twice the depth. Use a featherboard to keep the metal from lifting and a push stick to keep your fingers out of the way. Clamp the guide board securely to the drill press table and Bob's your uncle.

BTW - at 48 I have all my fingers, all my toes, both eyes, both ears and some of my hair
