So the kids want a tree swing. None of the trees on our property have an outward branch, fit to hang a swing from. The style of swing is the classic, single-seat, wood bench with rope on either side. My plan is to stretch a line between two trees and hang the swing from that. We'd like to keep it natural looking, so trying to avoid cable or straps. I was thinking about using a 1" diameter hemp rope (or similar style) wrapped/looped around each trunk, and secured with knots (bowline, taught line hitch, timber hitch, etc.). I was even thiking about doubling the line between the trees (two passes of rope) and using U-bolts to keep them joined together. The U-bolts could also double as stops to keep the swing ropes from sliding along the horizontal line, between the two trees. I'll alo be sure the tree trunks are protected from chaffing.
Here are some pics of the trees in question. Additionally, here is a napkin sketch of the plan. Both trees have a branch that I could utilize as a vertical stop for the rope. I will also be sure to check the forward and rearward travel distace of the swing, to ensure there's clearence...don't want anyone to hit the fence!
An additional requirement: this needs to support the weight of teenagers and adults.
So what say you? Will this work? I'm trying to keep it simple. I thought about running a beam between the two trees, but that might be overkill. I want it to be safe, but not over-engineered or overly complex. My one concern is even with a taught line, how much sag will there be on the center of the line, with weight on the swing?
