Thanks to you guys for helping me out. I made the whoopie sling and attached it to my platform. Took it out to try at ground level and had some issues. First the platform slid down a few inches. This was on a wet slick cedar and I think the bark peeled away from the sling letting it slide down. So I switched to a tree with rougher bark and noticed the platform had a lot of side to side movement. I attempted to tighten the bolt, but the platform still rocks back and forth on the bolt. Any suggestions?
Thanks.
Thanks.
