Hi, I want to fix a swing to an angled tree branch. If I attach both ropes to the branch the swing twists. I understand I need to put something rigid in, so that the pivot point for both swing ropes is at the same height.
I thought the easiest way to do this was to fix through the branch using M10 threaded rod, penny washers and nyloc nuts on top, the rod extending below the bottom of the branch, with an eye nut or coupling nut and eye bolt at the bottom.
Any thoughts on this? I know you shouldn't use threaded rod in shear but M10 has a shear strength of 23kN so way above 1 person swinging. Total cantilever distance from the upper branch 30cm.
How do I ensure the bottom eye bolt/nut is properly fixed? I was thinking of eye nuts, but there's nothing to tension them against. How about eye bolts and coupling nuts, all fixed with loctite?
See picture. Thanks.
