i actually like doing it.. i did my pinch bolts and calipers since the last track day.
You're messed up!
I enjoy it too.
It is a pet peeve of mine to see a track bike with sloppy wiring. I guess it goes back to my Naval Aviation daze when I was had a "P" school on safety wiring.
I hear you on that...I see what people do at the tracks and laugh...our inspectors at work would make about 95% of them do it over but again that aviation standard. Safety wire is supposed to be taunt and clean with pig tails and alternating directions of twist after each point...but hey these bike are on the track, not in the sky doing mach 1.
Individual interpretions of the FAA's guide book can be derived from
http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/99c827db9baac81b86256b4500596c4e/$FILE/Chapter%2007.pdf Page 19 starts the description of safety wiring. It is worth looking at as there are diagrams showing how it should look. My example would probably fail for not maintaining a light tension. BUt as long as the bolts are pulling tight against each other, don't cut or poke my skin and I am not leaving the ground for extended periods of time I think I will be OK. I was taught to drag a cloth across the end of the wiring job and if it does not snag it was good.
Here is an excerpt from the chapter:
7-124. SAFETY-WIRING PROCEDURES.
There are many combinations of safety wiring
with certain basic rules common to all applications.
These rules are as follows.
a. When bolts, screws, or other parts are
closely grouped, it is more convenient to safety
wire them in series. The number of bolts, nuts,
screws, etc., that may be wired together depends
on the application.
b. Drilled boltheads and screws need not
be safety wired if installed with self-locking
nuts.
c. To prevent failure due to rubbing or
vibration, safety wire must be tight after installation.
d. Safety wire must be installed in a manner
that will prevent the tendency of the part to
loosen.
e. Safety wire must never be overstressed.
Safety wire will break under vibrations
if twisted too tightly. Safety wire must
be pulled taut when being twisted, and maintain
a light tension when secured. (See figure
7-3a.)
f. Safety-wire ends must be bent under
and inward toward the part to avoid sharp or
projecting ends, which might present a safety
hazard.
g. Safety wire inside a duct or tube must
not cross over or obstruct a flow passage when
an alternate routing can be used.
