@FrontSideBus If it's a non-stop project, it takes a week or two, and often an engine build goes in stages, with delays in between, adding up to months sometimes. A time lapse of an engine build would be a project that just couldn't be done in our busy shop. Placement of ( and not disturbing ) my camera for that length of time would not be possible.
@bashue69 Many, because it is also converted from a self-sufficient aircraft engine to a skid supported stationary powerplant. It needs different fuel nozzles and a different fuel manifold. Its missing: Fuel pumps for main and afterburner system Fuel control apparatus Fuel filters Fuel flow measurement system Oil tank Fuel-cooled oil cooler Engine monitoring system Afterburner & afteburner actuation system Throttle interface with pilot Electrical generator Hydraulic pump ...
@YoungJim409 Yes, very good, but is obviously written for airframe mechanics and not engine techs. How can I tell? Because at step seven the correct procedure is to Stop - and find that piece of lockwire... no matter what, no matter how long it takes and no matter who is watching. Then, all the rest can and does happen... I especially like condition 30 !
@krbruner You wouldn't lock a bolt to the nut it passes through. Some nuts are drilled for lockwiring, and they resemble the female hydraulic fitting just above the pin I lockwire. you get a good look at it right around 1:00. The wire hole goes through the apex of one of the corners. A nut is drilled the same way. Usually if a bolt is by itself, there is a lockwire hole drilled through some other structure that can serve as an anchor.
After watching both episodes suffixed as 1. & 2. I finally got the mystery out of lock-wiring; will go ahead and remove rust accumulated on my (shelved) pliers.btw, I also learned: The more you twist, the harder it gets :)
Thanks for this man. Haven't safety wired in a long time, but will be starting a new job and this will be required. But I didn't think anybody still used the J79's anymore.
Right now I am working with a US Air Force maintenance manual for our Garrett GTC 85-27 start cart engine. It lists Lockwire as a necessary consumable. We have always know what it is. Is seems that you guys keep changing you minds...
AgentJayZ Lol ! I am just an artist but I enjoy looking at you hand restoring planes. My grandfather Flew for United for 50 years and I have a lot of his old manuals laying around. I love the manual "THE AIRCRAFT GAS TURBINE AND ITS OPERATION" by PRATT & WHITNEY which describes all parts and has elaborate illustrations of the working parts of the 747 GAS TURBINE.
You have shown the locking of bolts into threaded holes. What if what you are lockwiring is a bolt and nut on like either side of sheet-metal. Do you lock wire both sides and what does a nut look like that is capable of being lockwired, since obviously you cannot pass the wire through the whole through the nut? Also, how do you lockwire a bolt or nut that has no other bolts or nuts around to be wired to?
Have you ever used a lock wire gun? MUCH easier to use, but there is considerable wastage with them.. and it is expensive to order the cables. But still it takes almost all the difficulty out of lock wiring.
Those lockwire pliers always remind me of a crocodile doing a death roll Crikey!

What was the context for this 7-years-old reply?
This answer is amazing. WHAT WAS THE QUESTION??

It's easy to see why overhauls are so pricey.

This guys so Canadian calling saftey wire lock wire.
lol !!!!!
If my subwoofer gets any louder I may just use some safety.
Gr8 vidz as always.

Safety wire is a bish! Thanks for this video... my first time Safety wiring took me 4hrs to get 18bolts LOL
Good video as usual.
Ever thought about doing a sort of time-lapse of an engine being built or set up in the test cell?
Is that a J79 from a F-4? Maybe F-104/CF-104?
thaaaats pretty darn neutral
What diameter wire are you using here?
+Kirk March Almost all... almost... of the lock wiring we do is with .032" wire, made by Malin.
almost all .040 is used on props, thats it, even jet wheel hubs are locked with .032
Lockwiring test tomorrow :)
howd you do
@@t0ad3r that was 8 years ago😂😂😂
26 is also very funny

Tool is expensive as well. See Lockwire (pt.1)
Excellent.
looks like a perfect place to put the crimp end safety wire!!
Nice Video!
