pole that's pretty dang slick
I guess we should try all the hitches that are meant to withstand a lengthwise pull, on a slippery stainless steel tube. With some of those hitches the relatives diameter of the rope and the tube play a great role. Derek Smith has suggested :
high gloss chrome plated steel tube
the Well Pipe Hitch simply doesn't budge....It even held it's ground using only two round turns with 550 Paracord.
I do not question your strength !
If you can manage to make a
2 turns Pipe hitch to hold, imagine what you can do with the TackleClamp hitch -
when you will tie it properly/correctly. Because, as you have said once in a previous post - but perhaps have forgotten by now - the TackleClamp hitch uses a mechanical advantage that the Pipe hitch does not, so it can be tightened harder, and so it can withstand a greater lengthwise pull... in fact, a much greater lengthwise pull ! Also, with a multiple wraps Pipe hitch ( the one shown in ABoK and everywhere else, and the only one that can hold without having to be tightened by a weight lifter...
), one can pull the one only end of the "coil tube". That places a limitation on the amount of tightening of the coils that are far from the standing end, because of the reverse capstan effect. On the contrary, at the TackleClamp hitch you can pull both ends, the one after the other, so they will be no round turns that will not be tightened. Moreover, because of the "locking" of
both those ends, you can have any tensile forces inserted into the round turns be "locked" within the knot, and be ready to prevent the round turns from becoming elognated, when they will be dragged by the lengthwise pull.
I repeat : Even ONE turn Pipe hitch ( if one can call still this "thing" with this name...) can hold , if it is tightened enough ! So, we do not need any other hitch than this "thing", do we ?
The friction hitches based upon many round turns have greater gripping force, EITHER when they are tensioned more, OR when they are tied with more turns. You prefer to wrap the pole with one or two round turns, tighten those round turns with your great strength, and then secure this "thing" with two half hitches ( because this is all what you do, this is all what is hidden in the pompous name "Well Pipe hitch"...). A less strong - but not less clever - guy, would prefer to tie the same knot with many more turns, and dispense with any need to use any strength whatsoever. I have attempted yet another road, that was not taken till now : I use just a few round turns, but I pull them from either of the two ends of the "coil tube" with a moderate strength, using a mechanical advantage - similar to the one achieved by a simple "block and tackle" machine ( hence the name " Tackle- ). Moreover, I use the mechanism of the "end-going-through-two-opposing-bights" "lock", to secure the induced tensile forces into the hitch, right at the moment they are applied during a pre-tensioning (by pulling both ends against the pole) phase - so those forces will be able to remain there even before or after the final lengthwise pull is applied. I
"lock" the standing end as well as the tail - that is the meaning of a "tight hitch ". (1) The Double Cow hitch, which is the easiest hitch to tie after the Single Cow hitch, is a tight hitch, but does not use the mechanical advantage of a genuine TackleClamp hitch. Of course, as a tight hitch, it can be pre-tensioned, so it can hold much better than the "round turns plus two half hitches" not-bad knot, known by the pompous name " Well Pipe hitch". Now, I can understand that if you have not tied the Double Cow hitch, you can not tie the TackleClamp hitch either, because it is a more complex knot to tie than two Cow hitches, the one next to the other ( because this is all what is hidden in the less pompous, I believe, name " Double Cow hitch" ). So, I suggest the
prudent thing for you to do is to delay the pompous phrases like
"blows [TackleClamp] hitch out of the H2O" (sic),
" the Tackle Clamp deal's been cuffed and stuffed" (sic), and whatever other clever phrase you are preparing to say... I advise you to respect this knot, because it is a
superb knot, and we should respect such marvels
works of nature, the KnotLand has offered to us, for free !
P.S. I would have been glad to watch the rope, when you will tighten a TackleClamp hitch with the same force you tighten the "two-round-turns-and-two-half-hitches" "thing" and make it hold ! Or better, to
listen to the rope - because it will swing, believe me !
