The easiest method I have found to remove key pins is to pry them out using side cutting pliars to grip them and a hammer shank or something similar as a fulcrum resting on the rail to pivot the pliars on so the lifting force on the pin is straight up. This will give you great leverage and it is not difficult to lift them straight up so you do not damage to holes. I like the idea presented of using a drill press to insert he new pins but another way is to drill a hole in the center of a hardwood dowel equal to the height that you wish the pins to stand. Using this dowel as a driving punch all the way to the rail will leave the pins standing the exact distance that the hole was drilled. These two ideas would be a lot easier to demonstrate then to describe but I hope that you can visualize how I do this. Norm Barrett
