[Elecraft] Locktite

[Edward R Cole]

First off my K3 (SN-4043) probably does not have stainless hdwr and 
no evidence of rusting living 2mi from saltwater.

I used blue locktite on 8-32 ss hardware assembling my 6m beam and 
has survived well normal wind vibrations.  I guess those living in 
the highly urbanized world do not drive on unpaved roads so would not 
see abnormal vibration.

The worst mobile radio install I encountered was putting a 100w 
GE-Mastr-II into a D8 Cat on the Alaska North Slope.  It survived 
less than 24 hours.  I drilled and tapped 1/4-20 holes for mounting 
and the internal hardware all loosened and the whole insides fell apart.

I was new to mobile radio at the time (1982) and was not aware that 
they made anti-vibration platforms for this kind of service.  The had 
spring-mount with small shock absorbers between a metal subchassis 
plate and the vehicle.  Not my fault as my employer just showed me 
the work list and left me in charge of the shop.  After an hour on 
the job: "Here's the keys, here's the work list, don't shutoff the 
suburban, see you in three weeks".  High temp was -15F outside.

I worked 18-hour days x 21 and hauled some cash home...never went 
back up there, again.
