Pretty sure you're overthinking things.Design question: seeing how many fasteners are present, wouldn't fastener loosening be a problem w. Long term exposure to washboards and related vibration?
I have zeroed in on this product for my rig but concerned about it shaking apart. Some of my thought on this:
a) once installed and adjusted correctly, mark configuration, take apart, install industrial grade double sided tape between all mated surfaces, the reassemble.
b) tack weld all mating pieces together after install.
With any method, locktite all fasteners w. Semi-permanent stuff (takes heat to break the thread bond).
In aerospace, design practice dictates safety wiring all nuts/bolts in high vibration environments.
Am I missing something?
