Best knot for temp joining 2 ropes??

I wasn't clear; I meant that I would form a sheepshank around any joining knot that might jam,  in the same way you might round a damaged bit of rope, in the image below imagine the joining knot or frayed bit being in the central length. I always put a stick in the bight and around the standing lines

 

Note  this way of joining  halves the strength of the weaker of the two ropes, the alpine butterfly retains about  three quarters the strength.

Was just looking at the picture off the reef/double fisherman's knot.

 

I know some have said put a shackle in reef knot, which I can see working.

 

But without the shackle ( or in normal working situ u've left it in van and are too lazy to walk back for it) would the reef knot not be very tight by the time it has pulled the 2 fishermen stoppers up close.

I know reefs can pull out under pressure but they can also grip and go as tight as a tight thing.

 

Think I'll look into the zeplin a bit more.

 

Atleast now with my rope being already cut its no buggy to have to cut an experimental knot gone wrong, I usually hate cutting knots out of rope even on thin poly prop or baler twine

Just thinking I imagine u dress the knot up so fishermen are tight on reef before u start pulling.

So ignore my last post

Yep that's the one Jules, good picture, I guess worth a try with single fisherman osm, but not done that

Here's a double fishermans bracketed by a sheepshank. Possible, but I wouldn't want to do it up a tree in a gale with cold fingers.

And here it is with a reef knot.

I used an alpine butterfly on a rope that was being used to winch a tree over. Took me 10 minutes and a marlin spike to untie it.

Rubber mallet works well, also double apline is easier to untie

Dan Maynard - I struggled to remember the zeppelin as well , until I heard an alternative name the

'b & q ' knot. After the occasional  bit of frowning I haven't forgotten it since. Those who don't know it, you make a b with one end of rope and a q with the other , and then you are almost there.

Nor me but I had thought we were discussing this in the context of using a machine to pull the rope and joining a snapped rope.

I like that, good idea, thanks.
