Subject: [TowerTalk] Lockwasher comparrison
This video shows the comparison between various ways of locking nuts.
The reaction to a lock washer and vibration was a real surprine. Only
one method actually worked.

## I dont think you will loosen bolts and nuts when blue loctite is used....
and esp red loctite.
They should re-run the tests again, but using a flat washer under everything.
Also, what else
that might work is double nutting, but using 2 x nylocks.
## It appears that they used never seize goop on the threads. That alone
should reduce the required
Torque by a good 33-40%. It would be interesting to place your fingers on
the assy, shown in the video, while
it is vibrating away. If stuff is vibrating loose within 2-20 secs, it must
be one helluva vibration, not some subtle,
gentler, vibration.
## Note, there are several other cos that make identical washers as the
nordlocks..and no where near the price tag.
There is only one correct way to install the pair of nordlock washers..and
several wrong ways.
