Looking good as usual, Steve, and glad that you were able to source some parts while here on your holiday. That's a different use for safety wire. Is your thought that it's serving a double purpose, first keeping the studs from loosening, plus acting as the pin in the castle head nuts or do you just like the look? Normal security for a castle head nut is a cotter pin. Just wondering....

It won't stop the studs from loosening Roger just the nuts, I just like the look really, the studs are loctited in with blue loctite, they won't ever come out !!!

Not a big deal Steve, but properly installed safety wire would keep the studs from loosening, but technically safety wire would not be allowed on a castle head nut in safety service (aircraft fasteners, military engines, even professional racing, etc) because the hole through the bolt and the slots of the nut create a shear plane on both sides that tends to cut the wire if it loosens. Not saying that it's wrong for your service, but it wouldn't pass QA/QC on a military application. A cotter pin would be used on a castle head, but I think it looks trick, too.

Had another thought while riding the tractor/mower for what I hope is our last mowing of the season... If you want to make it more "authentic" you might consider abandoning the hole through the stud and the castle headed nuts, and invest in a jig to drill across the corner of a polished hex nut for the safety wire. Here's the first that popped up on EvilBay - Safety Wire Pliers Guide Block Universal Nut Jig | eBay You could then wire the nuts such that the wire pulls to tighten, not more than three together, and with the twist on the wire between 6-10 twists per inch.
