samsara straightened it out
samsara basicly explained my setup better than I did. I used the 2x4 for the same reasons that TurtleLady did. The poles on my back deck were not strong enough to support the compression loads (they were hollow metal) and I needed to position the hammock a bit better under the deck overhang. So my only option was to drop the lines from the beam and use the wood as a very long spreader bar. I used the 2x4 because I had it in the garage.
I have moved into an apartment with questionable construction, so I need to reduce the stress that any type of attachment point would apply. And my thought was that using the 2 piece pole method for the bar would allow me to hang the bar from the ceiling while I'm home. (and save me the precious space that I have so little of in an apartment) Then break it down and toss it in the car with some of the Turtledog Tripods for road trips.
I guess my question boils down to if anyone is hanging the pole directly from the ceiling for indoor use. Rather than using the tripods.
And I guess a second question of, other than the straight forward question of the beams holding up, is there any other unexpected issues that have surfaced with this method.
