The Ford Barn - View Single Post - Why no lock-washers?

I have backed off some old nuts on model A parts before and the lock washers are either A flat or B crumble into bits undoing the nut.

Yes lock washers job is to prevent stuff from turning but heat cycles it does not prevent.

Ive put nuts in a vice and tighten them till i just barely see the nut squash. By the time you release it will spring most of the way back but it will be an interference fit .
