Re: Mother Mallard's Mobius Tape Loop

["J.G. Wong" <adaaxs@erols.com>]

Those half twist loops they are referring to are set up as an endless
single reel of tape like on an 8-track or a commercial 1/4' cart
machine. You actually only use one side of the tape, the twist in the
tape and the fact that you only  have one reel that it returns to is the 
trick.

1/4inch loop adaptors for reel to reel machines are very obscure
accesories, but they are better than having someone hold a pencil at the
other end of a football field.  I rarely get down the hallway anymore.
