Ok.. I know some of you will wrinkle your nose at putting a swing in a
tree but still need the info.

What do you think the better method is for attaching a swing to a tree.

1 Looped rope over the limb and tied.
2 Garden hose over said loop.
3 Use a closed eyelet screwed into the bottom of the limb.

Which would do the least harm to the tree.. Tree would be a huge pecan,
on a 12-16" diameter limb.

I'm leaning to the eyelet as being the best for the tree and safest
method. Only need one rope to swap out between a hammock chair and a
tire swing.

Eyebolt through the limb, fender washer and hex nut on
the topside. Eye should be welded shut so it won't open
under the weight of a heavy adult. Replacement part
for a quality wood playset (i.e. Woodplay, NOT HD crap)
would be best.


1/2" stainless won't open up. Mild steel with zinc coating may. My
definition of heavy adult is 300 lbs or less. You don't want my
description of an adult over 300 lbs. Again, I suggest 2 eyebolts. One
for each chain.

Hex nut is to prevent eyebolt from walking out the limb. That won't
happen if the limb is adequate, you don't predrill a hole too close to the
diameter of the eyebolt thread diameter, and the threads are of adequate
depth.

If you're talking wimpy 1/4", 5/16", or 3/8" hardware, or mild steel with
zinc coating, sure, do it. None may holdup the mother-in-law,
irregardless.

Occurred to me you may talking about the all-thread version of an eye-bolt.
If so, the longer threaded version of this (vs. a lag screw type) requires a
nut/washer at the end of the threads and another nut/washer to snug it on
the eyebolt side.

The lag screw type, if properly mounted and has adequate limb depth, won't
turn while the swing is in use.

In either case, the material diameter of the eyebolt is the most critical so
the eyebolt won't separate due to weight stress from the chain the swing is
hung from. True stainless steel is stronger than mild steel with zinc
coating.
