I'm hardly expert, but I've done it. The art of wirewrapping revolves
around one basic principle:

NEVER CHANGE LEVELS!

eg. posts will accept 2, 3 or 4 wraps per post.

When you wrap on a post, if it's the first (bottom) wrap, the other end
of the wire must be the first (bottom) wrap. If you are wiring a buss,
or a daisy-chained line like a clock, you do it thusly:


| | | | |
z.......z z.......z z.... . .
z z......z z.......z

The reason: rework. You'll rediscover all the First Principles if you
have to rework/repair/modify something done wrong.



THere's a variation in wirewrap gun types, the fist turn is with/without
insulation. I've only done prototype stuff that does the turn of
wire-plus-insulation, for added strength.
