    Great demo mate. If you cut notches for your slings they won't slip as much 👌

    The first time I saw this, they didn't have quite enough rope and it slipped out of the hand of the groundie, making a bit of a bang. No harm no foul. Gotta think the groundies need to be sure they don't get a twist in the line so progress doesn't come to a dramatic halt. Fun demo.

    Enjoyed the video. Very interesting. A good rigging method if you're dropping Heavy spar chunks. But, as you said, setting this up takes time. Probably shorter and easier to chunk smaller pieces. A good experiment. Thanks.

    • @zaccheus
      @zaccheus  10 месяцев назад +1

      Thanks! I think you're spot on. It would be interesting to time a cycle of each method and see if set up time is double that of a single block system. If it's less that double the time, double blocking would be faster, if it's more that doi le the time, single blocking would be faster.

    I am very happy I stumbled across this today, I've been trying to put together a system like this the last week! Nice demo with some tips, and why not to have an ultrasling ring on the piece. I'm curious what would be the benefit or detriment of swapping the block and ring positions. Having the block on the piece and the ring as the redirect on the stem. Any thoughts?
    (I'm trying to make it Knotless and since the block can detach midline I could still use an ultrasling with it on the piece. The other idea I had was to use a dyneema shoft shackle almost as a quick link to connect the ultrasling to itself though, isntead of passing it through itself directly, that way you can still unlink it if you used rings and didn't want to pull all the rope through to undo the sling. But I don't know if I would trust it to be durable enough to use often without worry)

    • @zaccheus
      @zaccheus  Месяц назад

      @TylerHope-jb4vx You could set this up wither way. I put the ring on the piece because it's most vulnerable to damage since it's flying to the ground and the ring costs less than the block. You could certainly use an ultra sling, but then you'd have to untreated the rigging rope from the sling every time to get it off, which would probably negate the time savings of the ultra sling 😅
      I would avoid using dyneema in a dynamic rigging scenario. Because it doesn't stretch much, it has a low capacity to absorb shocks from dynamic rigging systems. In theory, it would be such a small link that it would probably be okay, but I would still avoid it if possible.
      I dint know if there is a reason nobody makes soft shackles out of nylon or polyester, but it might be something to experiment with if nobody has tried.
      Another thing to consider is that soft shackles require some tension to keep them engaged. Alot of dynamic rigging systems might unweight the rope for a moment and cause the soft shackle to come off.

    Cool video! Just out of curiosity, could you have cut the notches deeper on the chunks you were removing? If they were almost straight up and down, i think that would change their center of gravity and make them tip over a bit easier for you... unlike a full standing tree where you would want to have as much hingewood and control as possible, these would fall amd break away faster. Also, depending on species, kerf cuts may make it a bit safer for you. I learned that the hard way. Stay safe man!

    • @zaccheus
      @zaccheus  4 месяца назад

      Thanks! I could have made deeper notches so gravity would take the piece instead of me pushing on it. It requires more cut time as angled cuts are the slowest. I also prefer to have the saw shut off and put away before any falling action. I believe it to be safer. And yes, sap wood cuts are important on certain species or at certain times of the year.

    I personally haven't done any chunks big enough to push my rope too hard. Have you seen rope glazing much when using rings? I know you were experimenting. I could see myself doing this to do more with my 1/2" rope. Got a spool of Sterling Atlas for 300 bucks so that's what I've been using.

    • @zaccheus
      @zaccheus  10 месяцев назад +1

      I have not seen much glazing. I don't use rings very much becaise in some of my experimentation they have gotten too hot to touch, and that doesn't seem like a great idea. I don't have any facts to back that up, it's just my intuition. I did think about doing this with a half inch rope and I think that actually might be more worth while than the big stuff we used in the video here. It would definitely be easier to set up, that's for sure. The rigging I used for this was way over kill.

      @zaccheus I have a Notch triangular shaped "ring" with the three holes. Maybe this winter I'll see if I can run 1,000# or more thru it and see what happens with the 1/2" rope. There will be more friction at the ring but it has much more mass and bearing area than a regular ring. With shorter trees though, I doubt I'll see a lot of heat. Height will make a big difference.

      @@zaccheus I bought one for 40 bucks - couldn't say no. Treestuff or the other shop sometimes has them for cheap. You just have to make your own sling which is easy with Tenex Tec or similar. I have the black triple thimble which I think is a little smaller than the shiny non-anodized one. Hole size might be similar but I think the aluminum colored one has a deeper sling groove. Not sure but Notch changed something and closed out the black ones.

      @jakubhostinsky4482 10 месяцев назад +1

      @@zaccheus For the sake of simplicity, lets say that termination of you rigging rope was at the same high as the yellow block. Then lets say that from the block to the ring it was 1 meter. So after you tip the log over, it will fall 2 meters until the rope will catch the log. Lot of speed, lot of energy. On the 2nd attempt it looked like distance from block to ring was only 20 cm, so free fall part was only 40 cm - in that distance the log had less time to accelerate. If your groundsman is good, then no problem in both situations, but if he had 4 raps, I would say that in the 1st case the rope would tear apart, in the 2nd case it would have more chance to survive. Experienced groundsman is a bless :-)

      @zaccheus  10 месяцев назад

      @jakubhostinsky4482 Haha yes, I would agree that a quality ground man is worth his weight in gold! You can only rig as good as the ground crew can rig. I think more than the linear amount of rope above the block, the distance between the block and the cut matters.

      Thanks! You need 150% the amount of rope that you'd would normally need. I'd imagine you'd only need to use this pretty low in the tree, though. Might be worth using to reduce load on a spar high in the tree, but I think it would only reduce it by 25%.

      Thanks, Stephen! I probably would have aimed for a little smaller piece if it was a heavier wood. I didn't want to push the limits too hard on the first go around.

    You prefer this setup to a SafeBloc?

    • @zaccheus
      @zaccheus  10 месяцев назад

      Ive never tried a safebloc. Thinking a moment produced these thoughts for me: the safebloc would reduce force on the stem for sure, but double blocking will reduce force on the rope and a little bit on the spar. The safebloc has some really tight bends which makes me nervous for use with big ropes and heavy loads. The safebloc would definitely have a faster cycle time.

    • @boomupengineering
      @boomupengineering 10 месяцев назад

      I have the smaller brother of the SafeBlock...the triangular one. But I have not yet pushed it very hard. It does have a lot more mass than a ring but it will also be generating more heat than a ring since there is more friction at the triple thimble. But with more friction in the tree, there will be less load pulling down on the block. One of these days I'll cut some bigger chunks and see what kind of temperatures I see. However, that will depend greatly on how far the chunks free-fall, how fast you slow them down and how far they drop to the ground. Many variables as to how much heat is generated and how hot the triple thimble will get.

It would help you get the bridge way shorter, and it would last much longer than the ring on the hard corners of the playe.
