I'm working on my fathers' log splitter (replacing the arms that hold the logs on the sides) by replacing the chinese 3/16" metal with some beefy 1/4" plate. I've have the arms cut and grinded down but I need to drill 4 holes in each arm. I'm trying to think of a way to drill a hole through all 4 arms at one to keep everything aligned. I do have a drill press and picked up a new set of drill bits. My current thinking it to stack them all up, tack weld them together then drill the holes. Then grind the weld off and marvel at myself.
