I never used a MAD unit, Ray. I do distributors the way Fatkidd Hobby Products does it. It's not a drill thing - just a #20 straight pin or the pins you can buy with a colored plastic tip on 1 end. When I cut the telephone wire insulation, the end gets crimped down somewhat. Running the cut insulation onto the pin opens the hole and stretches the insulation slightly. Cut 9 pieces of the insulation and run them all up the pin. They not only stretch, but also keeps them safe from falling to the carpet monster.
If you want some pics of the Fatkidd Hobby Products process that I use, just let me know.
