[TowerTalk] Lockwasher Comparison

[Roger (K8RI) on TT]

That's the first I'd heard from that industry and I'm sure there are 
others, but most I talked to over the years didn't use locktite 
compounds once NordLocks became available.
I worked in a metal stamping plant (first job) and chemical plants in MI 
and KY.  None used LockTite. I don't know the reasoning.
