In the April 2009 issue of Model Railroader Pelle Søeborg wrote an article about how to "Improve a Walthers chain link fence. In the article, Pelle suggests drilling a .020" hole perpendicular to each fence post to intall wire. He didn't mention HOW to drill them. I have a couple of suggestions.
Although it DOES test one's patience to drill that many holes, it sure makes it easier to drill them using the suggestions listed above.
