Need help with a tire swing
I know this is probably a simple issue for you folks, but it is a problem
for me. We are going to put up a rope or tire swing for the kids. I have no way of getting into the tree (I have an adult form of muscular dystrophy, which has caused weakness in my legs). I can get the rope over the limb easy enough by using a fishing rod to cast over the limb, tie the fishing line to the rope, then pulling the rope over the limb. I plan to wrap the rope around the limb 2-3 times to protect the tree. My dilema is that I need a knot which I can tie at ground level, that will slip upwards to the tree limb when I pull one of the dangling ropes. I know this will be a little tricky as the rope coiled around the limb will have to move for this to occur. Hopefully, all will be loose enough for this to occur. Any help or other ideas would be greatly appreciated. Thanks, Jack Rogers |

If just using one loop a simple slip knot will slide up the lenght and tighten as tension is applied. Be warned... if you use this and there is a lot of weight, the know will never be untied!

I'm a little worried about the 2-3 loops around the limb. I guess if I can
find something to put around the rope that will allow the rope to slip through, I could just hang over the limb once and might get about the same effect as wrapping around the limb 2 or three times. Where can I get instructions on tying a good slip knot? Thanks, Jack "Harry" wrote in message ...

This was my fall-back if I couldn't work out something to allow tying to a
single rope. I'm not sure how the physics would work. It might be that if the two ends are several inches apart, the swing might go even straighter (not toward the trunk), because of the tension of the rope on the left and that of the rope on the right might hold it in the center. However, it might cause the tire to face sideways. I could probably eliminate the tire turning sideways by using eyebolts to connect to the tire or a separate rope looped through the tire that would cause the tire to turn straight. I also thought about connecting the two ends to a stainless steel ring, then running a single rope from the ring to the tire. I could probably get the ring about 8' in the air by standing in the back of my pickup. Of course, I'm just speculating with all this. The physics of the situation might run the tire straight into the tree! What type of rope is recommended for this sort of thing? I figure the larger the rope, the less stress to the tree as more surface area should lessen the tendency to cut into the limb. Also, a thicker rope would be easier to hold on to and would be less likely to cause rope burns. Any thoughts? Thanks, Jack Rogers "Larry Green" wrote in message ...

... . I can get the rope over the limb easy enough by using a fishing rod to cast over the limb, tie the fishing line to the rope, then pulling the rope over the limb. I plan to wrap the rope around the limb 2-3 times to protect the tree. I'm very skeptical that 1) you can wrap the rope around the limb and then move it (the "tensionless hitch" e.g., works precisely because of such friction) and 2) that that would in any case protect the tree (the load would STILL be borne into the tree on one side by the swing-loaded part, and the wrapping if anything might strangle the limb). ..:. So, I'd scrap this idea. Simply tie a loopknot to make a noose for the limb; OR, make an eye splice. There are two directions, he make the eye long enough so that it will extend fully around the limb and through the bight, making the attachment to the limb a larkshead/girth hitch (and splitting the load to two parts around the limb), or to have the knot/splice eye end before the line goes through the bight, yielding the traditional noose. While I can conceive of an *offset* loopknot that would ensure smooth running around the limb, let's hope that a simple Bowline suffices. You might want to pad the eye tip--which will be rubbed by the line going down to the swing--with something, like a piece of garden hose. Perhaps you will also like to have some think line connnected to the eye with which to haul down the loop & rope?! As for what type of rope, hmmm, if you live around some fishermans place of business, maybe you can land some used ground or mooring line. E.g., here's a light by strong copolymer line called "Polysteel", used by lobstermen and others: POLYSTEEL¨ Ropes are superior to manila rope and conventional polypropylene mono filament rope in virtually every respect. Polysteel¨ ropes are produced on a unique state-of the art computerized production line which monitors all aspects of the manufacturing process to extremely tight tolerances from fiber extrusion to the finished rope. The result is a rope of unsurpassed quality and consistency. Polysteel¨ ropes are manufactured from extruded copolymer (polypropylene and polyethylene) fibers whose unique properties result in ropes that, size for size, are almost triple the strength of traditional high quality manila rope of twice the strength of conventional polypropylene rope. Not only are Polysteel¨ ropes far stronger, but they weigh much less, making them easier to handle. --dl* ==== ps: Please delete extraneous copy of msg.s from your reply posts--no need to waste archive storage for that. |

By loop knot, do you mean something like a hangman's noose? I don't want to
keep a loop as it would cause the rope to move back and forth over the limb (the limb I'm using isn't perfectly parallel to the ground). The second idea sounds good, I just can't really follow. It sounds like you have two loops on the branch, the rope from which is joined somewhere below. This would definitely be better for the tree as the load would be split. Do you know of a link to an illustration that would help explain? I don't live near the ocean. The only "fisherman" type rope I could get would be ski rope. I'll check the internet and local hardware stores. The rope nearest the tire probably needs to be as thick as possible, giving the kids more to hang on to and causing less burn.

I would cast the fishing line over the limb and tie it to the CENTER of the
heavier rope, haul the rope over the limb, put the two free ends through the loop, and pull on them until the loop is snug against the limb. Then I would secure the ends to the tire, or, if using a seat, secure them to the seat. I would attach a wood spreader about four feet above the seat to keep the two ropes separated. Whew, I'm tired after all that! Hope this helps................Al "Jack Rogers" wrote in message ... I know this is probably a simple issue for you folks, but it is a problem for me.
