The operation is highly involved, a simple aproach to its solution, such as Lee, can never be acceptable. Also, you must spend more than 10 bucks for high tech equipment [>:]


Keep it simple, all you are doing is using a length guide to stop a cutter at a predetermined length. Load the case in a drill chuck once to cut and without reloading clean and lightly chamfer the end is the way to go. I then spin it between steel wool to shine the case up before removing it from the holder. Three operations without moving the object, efficiency!!!

Or, someone could complicate the issue, sell you another electrical motor that you need to plug in and take up space on your bench .....
