Nordlock vs Safety Wire

[Anon455]

How long has safety wire been around? I don't know, but I can say that I've cut .032" safety wire in 2014 that was installed in 1956.

Safety wire is cheap and it's got a really really long shelf life and it fits a lot of things.
No safety wire I've ever installed has failed - never.
Safety wire comes in stainless, monel, and inconnel (at least)
I don't really need to "check the torque" of something I've saftied.
Safetying a Hartzell CS prop with .041" takes 10 minutes tops.
You ever try to break .041" by turning the bolt?
If I drop a can of safety wire on the ground, I can easily find it within a couple of minutes.
.041" safety wire will go through the tip of your thumb with no problem (lets see a Nord Lock do that)
Safety Cable is an option to safety wire and it's that much quicker.

Most of all Safety Wire Just Looks Cool (when it's done right)

Thread drift. See post #1. Let me know when there is a YouTube video of someone safety wiring a WW 200RV prop in 10 minutes.

The wedges on the washer don't contact the mating surface on the engine or prop. The washers are used in pairs, with the wedges facing each other. That leaves the flat sides exposed on the outside, and it's those flat surfaces that contact your engine/prop/bold head.

What size are the screws on the blue Gascolators from Vans? Are they 8s?

The outside seems to have ridges. I've never used one so no idea if they "damage" the surface that they are touching, I would guess so.

Sorry, I thought the title of the thread was Nordlock vs. Safety Wire. But, if you find safety wire too difficult or time consuming and WW doesn't recommend nordlock, you should probably look into safety cable as another option or you can pay someone $20. https://www.dmctools.com/products/safe-t-cable/

Nice tool. Better be at $560 plus the cost of the cables.

If someone is willing to safety wire my whirlwind prop for $20 I’m all ears. Apparently they would be willing to work for less than minimum wage.

You can get them cheaper on e-bay, if you are not in a hurry.

Hey, good catch. I am familiar with the technology but haven't used them before so i've never held a set. I thought the person was asking about the "large" wedges that made up the locking mechanism, I didn't know they had tiny ones on the outsides too. It looks like they are angled to slide nicely while tightening the fastener, but to bind in if you try to undo them. That suggests you wouldn't want to use them in a location where regular removal for maintenance is needed... It looks like you'd remove a little material each time you undid them.

Oddly enough, in the photo at the top of that page, angle alpha looks to be less than angle beta...

What torque value do you recommend when using Nordlock washers for both the brake calipers, and the axel nut wheel pant bolt?
