Reference charts

Hi, Would anybody be able to provide me with a link to the following
reference charts:

  1. Stone setting calculations, such as “tube size + drill bit size +
    gemstone size”. Also, stone setting calculations/equations in
    general.

  2. Wire length vs. wire weight of various wire gauges. For example,
    one foot of wire weighs one gram. (I’d like to be able to calculate
    how much wire I would need to order for a weaving project.)

  3. Diameter measurements for non-round rings (like Friedrich
    Becker’s). In addition, are there any online tutorials on various
    stone settings - or very visual books? I’m a monkee-see, monkee-do
    type.

Thanx, ;-Devora
