For the first setting, maybe at least LockTite blue on the threads for the bottom nuts (would they be anywhere else?), set it up, tighten nuts (ouch), then let the LockTite set.

UH,

Yep, I use blue LockTite on both the lower nuts and (why not?) the upper wing nuts too. In case everyone is not familiar with LockTite it is a liquid applied to the threads that will "glue" the nut to the threaded rod and prevent inadvertent loosing BUT still will allow manually removal at a later date. DO NOT USE THE RED COLORED LOCKTITE as this requires the application of HEAT to remove the fastener!

PS - Why not replace the fasterners with metric nylock (nylon insert) nuts and be done with it?

Nylok nut, to work correctly, would need to go on plastic first. Another option would be to take the top plate off, add a jam nut, then reassemble, locking jam nut against the lower nut after tightening the lower nut against the upper. Takes almost as much time to describe as it would to do.
