Joining Two Ropes

He guys,

I was wondering what different methods people use for joining ropes and the reasons they use them.

I was taught to use an overhand because it slides over snags.

Two overhand knotts, doesn't catch on stuff, easy to undo and it has a second knott backing it up.

I avoid the double fishermans because it catches on stuff and is hard to undo.

Overhand, long tails. Although a mate I climb with routinely unties them and replaces the overhands with double fishermans. Never had either hang up impossibly.

Does anyone use Zeppelin bends? They look like they'd be good for this sort of thing but -- having done exactly no actual research -- I haven't heard much about them in climbing applications.

I use a single ended double fisherman.
Sometime I add a third to stop any potential slippage.

Zepplin Bends? Are you fuching insane????!!!

Didn't you hear about the accident those knots caused?

Clearly, no. Got a link?

Edit: um, unless you're not talking about climbing accidents.

Try a reef knot with a double fisherman for each loose end as a backup. Less bulk and easy to untie.

Bit of good old Gribble know-how!

Or a square knot finished with the double fishermans. :)

For abseiling : for ropes of similar diameter : overhand knot with long tails. for ropes of different diameters : double fishermans.

For fixed ropes : double fishermans then tie an alpine butterfly so that the DF is within the free loop of the AB so doesn't take any load unless the AB slips.

This is another instance of where the KISS principle is the best option. For a long time I used a Double Fisherman's, but changed to the more simple Overhand (aka European Death knot, so dubbed when English speaking climbers couldn't initially get their heads around something simpler and easier being better) about twenty years ago. It's quicker, far easier to undo and never gets hung up. All major advantages, especially when efficiency is a factor (when shouldn't it be?). As long as you leave long tails and tension each of the four strands there is no need for a backup knot.

Zepplin bends are the most amazingly un-jamming knot I've seen. You can tie them in tent twine and jump up and down on it and the knot will still fall apart afterwards.

Unfortunately this means they have the security of a mis-tied bowline. Especially as the tails stick out at the worst possible angles and will catch on anything. Yes, you would have to be stupid or crazy to use it for climbing.

Does that clear it up for you climbertron?

You could ask them nicely and they might let you join.

Sure does

One of the advantages of the overhand knot (EDK) is that its simplicity makes it easy to tie with gloves or cold hands.

Double fishermans. Bomber and works with any ropes. I've only ever got a (knot on a) rope stuck once, in the slot on the Mirrorball rap, where any sort of knot would get stuck (it's a crack that constricts at the end).

However, I do try to feed the knot over the edge whereever I can.

i would use a figure eight on the bight then another re-threaded figure 8 through the loop of the first one.
maybe even a double figure 8, that way you know your double backed up if one loop snaps.
