Something I have noticed Is that some toprails flex upwards, some down and some neutral. I'm thinking that it is dependant on where your hammock attachment and toprail suspensions are located. My hammock attachments are on the ends of the TR and the TR suspension are 6" to 8" inboard of the ends and the TR flexs slightly upward. Something like drawing a bow. Find that neutral point and richtorfla's suggestion should work with the hinge and barrel bolt. The sleeve sounds like a workable solution also. Like rich my physics and engineering are limited also. Have had a few experiences with gravity since hanging though!
Another good looking stand mys4sllc. These are popping up almost daily!
