You know how you use a pencil to take up the slack on an audio cassette? You can't do that with 3/4" U-Matic tapes, so I built this to attach to a pencil. While you could also put a drill bit in the end, I don't advise it as tapes will melt as the tapes are not designed to have friction on the tops of the reels (gravity normally holds them down from the top of the cassette.
