I'm starting on a large project to convert approximately 40 Atlas hopper and other freight cars to Kadee couplers. I have my shiny new MicroMark tap press sitting on the desk; have a small Ryobi drill press ready to work, but I have not been able to devise a practical method for accurately making starter holes for the drill bit to drill the new screw locations. Can't just whack it with a hammer and punch, because the force needed to make a good dimple would be enough to wreck the plastic superstructure. I tried drilling without a starter hole; epic fail; the small bit wanders all over the place. I figure somebody MUST know a trick for this...
Any and all thoughts and/or ideas will be greatly appreciated.
