And maybe using a steel top nut will get the wrench force tight enough without worrying about stripping the Nut.
You are using a proper headset wrench, on the adjustable cup , right ?
The nut isn't bottoming out, I've checked that. I do have a vintage Campy top nut that I could use, but I'll try LocTite first.
Are Campy headset wrenches good enough?
That's what I'm using.
