How to safety wire in a two-bolt pattern.

How to create nice and tight safety wire in a 2-bolt pattern. Pay close attention to the final "barrel-roll" technique at end of both twist steps. Watch the operator lock the tighness into the first twist after second bolt is penetrated. These are key to consistant, tight safety wire jobs. in high snag areas you will want to "hide" or tuck the pigtail away. Have fun!

    I had to look at your "barrel roll" several times before I saw the half twist that I missed on another fella's clip. : - ) Robert, if you're still watching, thank you. And I'll probably re-do the wires on a transmission input shaft bearing house for an OLD tractor. My twists are a little tighter yet the ends are looser. : - ( You fellas have done it often, I do it once or twice a year and it's very nice to get the refresher! Thank you!

    Why is the direction of the wire twisted in the opposite direction from the first twist (at 1:10)? Does it matter which way the wires are twisted? All the twist does is secure the wire to itself. Great video, and looks like a nice job! EDIT: Nevermind--- should have read the other comments first. Thanks for the video!

    safetying with wire is going to become a lost art now that safety cable has been on the scene. Its is now being widely used as standard process. I will always love safetying with wire better. it soothes my soul as if there is nothing better to do. LOL enjoy.

    I will start putting up more on typical maintenance techniques I have accumulated over the years. Thanks for the comments. For the wire on a 3 bolt pattern installing it takes a bit of practice, but when it is finished, all fasteners should pull the adjacent heads in the pattern in a tightening direction E.G. RH threads would be clock-wise.

    +Aj Watson If you look really close with magnification at the point where the wire exits and rejoins with the other stand at the pigtail, the opposite direction in the twist locks the wire to the bottom of the bolt (or nut) ensuring the wire doesn't ride up to the end of the hardware and eventually work itself loose in high vibe situations. Thanks for watching.

    For these kinds of the bolts it doesn't matter. You can twist right or left, lockwire doesn't go over the bolts head. I was told that by instructor and I agree with that.

    @@MrD1maS for me its about keeping everything snug and snag-free.. The pigtails, if not tucked outta the way will eventually be broken inadvertently from being bent so many times. Additionally if left high, when a pigtail is bent down, away from the head wrap strand, it could cause that strand to ride up off the head and possibly in the way waiting to be snagged or scuffed. Just remember...keep it straight, right number of twists, no gaps at entrance or exits and hide as much as possible reducing snags. Keep in minds that if your pliers have a very convenient knurl and they have excellent clamping force, there is a cost of that convince by the marks (weak spots) in the wire.

    Thanks for the comments. Years of practice building jet engines, composite and metal fighter jets, commercial aircraft has given me the ability that I can share with you. S Pliers are cheap from any aircraft tool supplier or more expensive from standard pro tool dealer. These cost about $19 when they were new in 1987. They still work. The less moving parts and when lubricated often will last a lifetime. Not to be mistaken as side cutters or a hammer...lol.

    For what it's worth to further clarify: If one nut turns "left" it would have to turn the other nut "right" and that would be impossible since it's already torqued down. That's the idea behind it, make it energetically unfavorable to loosen any screw. Also check out "nord-lock washer" videos. Kind of cool stuff, apparently really important for certain environments because they've a lot of work/research about it :D

    by the way Arran, you are looking at about 8 twists per inch. if you look closely at the opening pic before the video, with the scale held to the wire count the arcs in 1 inch either on top or on bottom is how you count them, but not both. top and bottom.

    two things, one, the wirelock should touch a minimum of two faces on EACH bolt head. also, you should never tighten by hand because you are then putting stress into it as you are creating different strengths along the wirelock and therefore a weak point rather than evenly spreading the load

    oh one other thing...a handy homegrown idea I think is now being incorporated on newer pliers is that the open relief that is machined (or cast) in the side of the jaws can be filled with RTV sealer that provides FOD prevention by holding onto waste ends of the safety wire until you release the handle.
