IBob Posted February 7, 2021 Share Posted February 7, 2021 I can't speak for Australia, but in NZ all the hotrod guys use it, so it's readily available through the various outlets that cater to petrolheads.........) 1 Link to comment Share on other sites More sharing options...
danny_galaga Posted February 8, 2021 Author Share Posted February 8, 2021 Ah, it's also called lockwire. Now I can see it on eBay. Is Mallin brand ok? Link to comment Share on other sites More sharing options...
IBob Posted February 8, 2021 Share Posted February 8, 2021 (edited) Can't comment on brand. You may want to take advice from others here on appropriate gauge etc. In fact, I'd like to know myself: I originally was loaned wire and lockwire pliers from a motorcycling mate. I don't know what the gauge of his wire was, but it seemed to me a bit light. So when I bought my own wire and pliers I got a heavier gauge, which is quite thick: the container says .032" diameter, which I see is 20 gauge. Mine also says SST 302/304 (it can't be both?) ANN (annealed?) ASTM-A-580 which is the spec. I'd have to say it doesn't seem to me to be overly strong. Or perhaps it's severely weakened when overtwisted, which I have learned to try and avoid. Later: just looked at Aircraft Spruce, and this is the stuff I have, so looks like I'm at least in the ballpark: https://www.aircraftspruce.com/catalog/appages/safetywire.php?clickkey=4386 Edited February 8, 2021 by IBob Link to comment Share on other sites More sharing options...

danny_galaga Posted February 8, 2021 Author Share Posted February 8, 2021 All I know is I was using .82mm, which was recommended by the kit manual. I had a roll of it, but I've gone and lost the stupid thing! 1 Link to comment Share on other sites More sharing options...

I have worked at a maintenance org, cessna piper airtractor etc, for a couple of years now and have never seen 0.040 used on a control turnbuckle. If however the manufacturer calls for 0.040 then that should be used. It would be a struggle to get 0.040 on to some of the more inaccessible turnbuckles🤔 2 Link to comment Share on other sites More sharing options...

I had done then with 0.032. I did read later that they did need to be 0.040 in my situation. These are wire for aileron, rudder and elevator control. I’ll look into it a bit more now. Yes the thicker wire takes some care and effort. Thanks. 1 Link to comment Share on other sites More sharing options...

It's only supposed to be twisted 6-8 turns per inch, according to the manuals 1 Link to comment Share on other sites More sharing options...
