At the risk of getting a bit OT, another bit of the memory about getting
those plied belts to lay up correctly.
As I recall, each ply is made to twist as the cord is plied. A simple
demonstration with a piece of string:
Double the length of string over, and pinch both loose ends betwixt
forefinger and thumb. Slide the tip of the forefinger over thumb,
causing both ends of the string to twist in the same direction. The
string will lay up in a two ply form. Fix the ends together with some
tape or a bulldog clip or the like.
Now, without allowing the ends to untwist, it will be found that
attempting to undo the laying up will be resisted, and the string will
spring back into the plied form.
Likewise, the belts won't come from together without the ends of each
ply being allowed to untwist.
That's all,
Clay.
