notch triple thimble

It's actually 22 inches (inside dimension) from brummel to the second brummel at the crossover/bury

I would've liked the cordage to have been disimilar sizes, and I actually bought some 3/4 to resplice the rings. However with a little use the cordage broke in and became supple enough it's not an issue

As for the bury being an issue it isn't really. Most of it sits where the "bridge" of the prussik is, rather than in the "coils". The tenex is also fairly supple after a bit of use.

If memory serves i did a locked brummel at the thimble end. Then the other end was a locked brummel with a single fid length tapered bury. Lock stitch in place and good to go. Nothing fancy (I'm not a professional spider by any means but it was what made sense to me for the splice)

Hey.. do you have a picture of it? I know there's one kicking around here somewhere but I can't find it.. been looking all day..

Maybe i haven't thought it through far enough yet & found the right instructions.. but how are you doing a brummel up top if you only have 2 ends to work with.. everything I've seen for a endless loop requires at least 3 ends (new england endless loop instructions).. Yeah we can do a one around the thimble because it's going around something, but up top i do the weave through with the two ends & all it takes is a straight pull & its out.. is your top brummel not a locking one? I know this may sound confusing.. im having a hard time explaining.. all i can say is the tails are just pulling right out at the top.

I just fucked this one all up.. realized i was too short to make what i wanted with the triple thimble so i tried a ring.. again.. tails just pull right out even with the brumel weave it whatever you call the splice i did in the second picture.
Check it..

Is this how you were doing the brummel up top?

Also.. even after doing a ton of tapering, the area with the brummel or whatever that was i had up there, is freaking huge.. I've seen plenty of pictures where it's not that big.. i can't figure out how that top splice & bury in pictures I've seen is so much smaller than what i ever up with... maybe the pics are just deceiving..

I’ve been using it right since it’s come out, way better then the safebloc, more control and can take bigger pieces with this over the safebloc, we use 1/2 Yale polydyne. I haven’t used my safebloc since I got this. You won’t be disappointed!

what do you mean you can take bigger pieces? do you mean it creates more friction with 1/2 rope so you can hold a bigger piece?

Sorry Lawrence, I should of clarified, bigger tops with brush, we still use the safebloc for spar pieces and go with 5/8 and bigger ropes to create more friction, the half inch rope on the safebloc wasn't creating enough friction for us. With having the crane now we don't do a lot of negative rigging anymore, maybe once a month, I'm trying to focus on large crane removals only now.

I wasn't giving you a hard time or anything. I've never worked with the triple thimble. I was just trying to figure out if it does offer much more friction with 1/2" rope. The Safebloc works better with 5/8" rope, it barely makes any friction with 1/2" rope. Alot of times i'll take an extra wrap around one of the holes just to get more friciton with it.

Man oh man, that crane must be sweet. I'm always trying to get more crane jobs but they're few and far between for me.

Pfanner.. by the looks of your YouTube channel, you would get bored having a crane everyday anyways..:descansando:
 
No he wouldn’t. He would just figure out how to get the most efficient pic out of the situation. Even though he’s a youngster that prolly won’t see or reply, he’s still close to a genius when it comes to rigging.
The triple thimble entices me but the safebloc has slowed they enthusiasium down a bit.
 
I had the safebloc Lock off a load resulting in the rope snapping. Oriented wrong in a negative rigging scenario. Pinned the line to the spar.

Wasn’t a critical scenario. We were just rigging to protect lawn. No big deal. Glad it happened there though

Ooooops!
Decent size peice? What type of Cordage were u using? Do you think it was more the rope getting pinched that caused it to snap or the locking of the load.. say it wasn't pinched & was locked off elsewhere, do u think it would it have still happened in your scenario?

Just being nosey..
 
It was 3/4 stable braid with a 10’x 30” red oak log. Basically the rope was to keep it tight to the stump since we were grinding and doing restoration. The ropeman only had 2 wraps on the porty so it wasn’t on his end. I think the safebloc oriented in the negative rigging to push the rope from between it and the porty against the spar. This was going off of his word saying he never felt a “tug” and looking at the length of rope left over. Really just bad luck but I’m back to blocks for negative rigging on a vertical spar.

Like I said, keep it close to the stump. A crash and burn deal. I would’ve doubled up the rigging if it was critical or gone much smaller.

haha! that's certainly kind of you to say but i'm not as young as you think, only 3 years younger than yourself actually. i'm no prodigy, just put alot of miles on this make and model ;)
and yeah, i love crane work (when i can get it) cuz it's a new challenge and a whole different way to approach the tree

i've had an SB turn over in the sling. what seems to happen is when the splice loosens up a bit the weight of the rope can "flip" the SB before you snug it up to the notch, it's real easy to not even noticed it happened.
that's a big ol 3,000lb log you had on there, glad nothing bad happened!

Is this a common occurrence?

I thought I wanted a friction block of some sort but my ISC 5/8” & 3/4” rigging blocks haven’t caused me that kind of grief.
 
I’ve never had it rotate in the sling to my knowledge. I’ve just quit using it on spar work. If that piece would’ve been critical, I would’ve probably had to sets of rigging on it and they would’ve been blocks. I have to try to keep everything longer than 8 foot for ease of disposal. Anything that length disappears for free or get paid for. Anything shorter we have to pay by the ton.
Any how I do think the safebloc has its place. Just not on huge pieces with a vertical spar for me.
Only crane job I’ve done since crane school this year Lawrence. I was good for five thousand on the spar with 135 ton crane. Averaged 2500 on the brush pics.

Does the triple thimble hockle ropes at all? It seems like it would...I just got mine and ran a 1/2" Samson through it and it had almost no friction at all it seems. A bigger rope will probably help but I wasn't dragging one out.

If you only use 2 holes, it does hocckle some. all 3 though seems to be hockle free.

As for sliding through freely, thats part of the beauty, when you add a load one and hold onto the other end, the friction goes up substantially. release the load, and the friction drops. It seems to be a linear relationship, more weight, more friction.

Which rope are you using? I'd be on samson stable braid...9/16 or 5/8". I'll be sure not to use just 2 so i dont destroy a $260 rope...or i can send it back and keep using the porty. Have you guys ever seen a port a wrap hockle a rope? In 15 years i've never personally seen it happen, and i usually use a single beast as a redirect unless pulling strait down, and then always use a block or a double beast for the business end. But there are guys out there that will tell you all about that one time they had it happen to a friend of a friend lol
