My question is: What size bolt would one recommend to handle the shear forces downward?
Also suggestions for how to attach the crossbeam suspension?
I'm kind of in the, "if it ain't broke, don't fix it" group. The TurtleDog design uses the gate hinges for the tripods, not the lashing. I find this setup to be superior to the original lashing method which is a big reason I chose it. I also think the gate hinges would be far superior and sturdier to the eye-bolt/bolt idea. I would actually trust my lashing over the eye bolt setup.
The image you have posted seems questionable. For a general use tripod I think it would be fine, but not for something holding a significant amount of load, like a hammock. I picture that collapsing as soon as a real load is placed on it.
If you were to try it seems like it would be best to use a shackle or something between the 'eye' of the bolt and the dowel, then you could hang your pole (or whatever) off that. Also, I think you'd have to use a spreader and anti-spreader of some sort to hold the tripod upright.
Of course, that's just my opinion and I'd love to see how it turns out if you try it.
