It's been a long time since I did knots in the Boy Scouts....
In Bob's Method 2, the square knot doesn't secure anything. It only acts as a stopper. What you need to do is take one of the laces all around the bundle and then make the square knot. Otherwise it'll just pull through the loop.

Hate to be picky but we need to watch what we're doing.

I think this is where the waxed finish comes into play.

When the ends are pulled tight per Bobs instructions I have not been able to get one to come apart. The "stopper" works.

PS being picky is good...

Yep, when you pull the bitter end the Larks head grips the lace, and the harder you pull, the tighter it grips. The square knot just keeps the whole thing tight.

I am sitting here at the office after having slaved like crazy this week to get everything done so I could comfortably scat to SnF next week. Well, I got done a few hrs early and decided to try to sketch this lace knot I was talking about and get it into a Jpeg.

The images may not transfer how easy this is to tie. Steps 1 2 3 can be done in about 2 seconds with your thumb and forefinger. Snug it down and then add the top knot at liesure because the wires are held with the initial snug loops. Maybe this is a chance for me to learn how to post a YouTube.

As said earlier, it is not AC43.13 but I am very satisfied with the security.

Looks good... I'm trying to work out what happens.

Does pulling the short end under the loop in step 3 make the basic knot into a clove hitch?

Gil,
Its not as clean as a clove hitch. I never have figured out what "classical" knot it is. (and I have Ashleys book ) In a way it is good because even though it takes a few more "jiggles" to get all the slack out, it stays put better than a clove while you tie the finish.

Just to give an admission, I know I have put the raw end through the loop in step 3 from either direction. The bottom as shown and sometimes from the top . It made no discernable difference while I was hanging upside down under the panel

Default knotty situation

For those who think tie wraps may be easier, me too at first. Did not understand why people complained about the sharp cut off ends. I think cut off tie wraps become harder, pointer and sharper with time. When you are building, you have more room to avoid the sharps. Once completed, there is little wiggle room and you will shread your arms. Compared to metal burrs and safety wire, it is a couple drops of blood compared to a pint. For the last year, every time I make a wiring change (and you will make many), I do not cut the tie wrap knowing it would cut me before being replace with lacing. Since under my panel is beginning to look like some strange catus garden, it must be time to start lacing. Maybe after wiring that starter engaged light.

Smile Alternative to Lacing and Cable Ties.

Hello Gentlemen (Ladies)

About 2-3 years ago on a TV programme called Dragons Den here in the UK a entrepreneur invented an alternative to cable ties. It's since taken Europe by storm.

The 'rapstrap' is soft, flexible, reuseable, and has no wastage, in my view a much easier alternative for those of us that never joined the scouts or are sailors!

Give this site a visit and watch the video. http://www.rapstrap.com/how-it-works

Default The perferct knot

A very secure method of tying a knot in slippery materials such as the waxed flat material from ACS is:

place three throws initially-tighten
follow with two throws-tighten
secure with an additional single throw-tighten

The three followed by two throws secures the wires in a snug fashion. The third throw locks the process. With minimal practice, this should give great results. In 40 years of surgical practice primarily with polypropylene sutures, this is a most reliable method.
