Natural Crotch Top Rigging?

When I used to work for someone else, we had no blocks/pulleys/anything.

He natural crotched everything, which was nice sometimes. It's been so long I forget how we did tops. So here I am the other day, about to take the top out of a small tree natural crotch. I forget how to run the rope, I make it work-but the way I see it in my head, is no matter what the rope wont really be able to run because one rope is wrapped on top of the other creating alot of friction.

Stupid question but how are you tying the rope in a typical V crotch when taking the top out?

Anyone got a pic or paint shop drawing?

The leg going to the top (or load) must be under the leg going to the guy holding the rope.

Quick and dirty picture with a broom handle and some cord I had handy.
 
tops

just make sure you make your notch first before you tie the bowline...

Thanks Brian, brain refreshed.

I do have plenty of slings and Blocks, somtimes it's just not nessessary to drag up.
 
Think ahead..leave stubs wherever possible to keep the rigging in place and to use as bollards for friction...then you can self lower.

I'll put up the video of Dave doing that cherry...that you asked about....when I can...but I have scads of other photo/vid editing to do.....

I always carry a sling or two on my saddle.
one can be used to assure that the rope stays in the chosen crotch.

But if you have no choice but to use a v-crotch...then gear up and false crotch it...

I shouldn't of said V. Think it confused a few.

A U crotch rather. I wouldn't natural a V, for a fear of jamming the rope in it.
 
Keep the load end on the bottom and the tether end outside or on top.

I've done, did, a lot of natural crotching and learned a long time ago if you don't get the wraps right you'll lock up the load.

And on drooping limbs and crotches where the line will run out,, a friction saver set with a wrap can serve as a false crotch to run the line through. In fact you can even put a line wrap through it to help brake. You'd be surprised how well it works to rope off drooping redwood limbs.

Talking limbs here. Nothing big.
 
Nothing compares to block and sling, specially if you love your rope.
 
I stopped natural crotching my tops after I saw a co-worker get nailed by the stub he had left to hold the line up. The groundie had too much friction and the piece was snubbed off, causing the top of the tree to shake back and forth like crazy. The climber got pounded against the stub 2 or 3 times, breaking his nose and front teeth out. Use a block!
 
Sean, if he was in the same proximity to a block as he was to the stub, if the same thing happened wouldn't he have gotten pounded by the block?
 
Bounce, we call that 'paddleballed'. :whine:
And that calls for better technique by both the climber and the ropeman. A poor ropeman can paddleball a climber whether he's using a natural crotch or a block.
 
Brians picture is correct for dropping a top out of a tree natural style.

We always add and extra half hitch (or whatever you wanna call the bottom of his set up) above the notch wich is missing in Brians picture.

All of that was operator error, not the natural crotch's. Plus, you don't need a stub to keep the rope on the limb.
 
Agreed..poor roping...not poor rigging..Why lug up a block when you can just abuse some rope?
Personally I wont use any mechanical stuff except for special situations and big wood...otherwise striclty natural

Maybe, but I don't think so because he could have put the block to one side or the other. Since he couldn't move the branch or his stance (was a hard leaner), he had to stand right in front of the branch.

you don't need a stub to keep the rope on the limb.

True, but I think you need a stub to keep the rope on the trunk, don't you? If you were blocking down sections of a telephone pole, could you still use the natural crotch method? I can't figure out how a round turn stays up there if there's nothing to hold it.

Why lug up a block when you can just abuse some rope?

:what: Because rope and houses are expensive to replace. Then there's the physics involved - by reducing the friction at the suspension point you put more rope in play to help absorb a shock load and make it easier for your groundie to let the piece run so you don't get "paddleballed" (nice word for that Skwerl) by the trunk.
