Micro Grab on false crotch

[emr]

I made a poor-man's PulleySaver and it works fine but my Pinto that is tied to a prussic loop doesn't adjust as easy as I want. I am wondering if I could replace the rope prussic with a Micro Grab and have it adjust easier. I would girth hitch the Pinto to a dyneema sling and the girth hitch that to the Micro Grab. I am not sure if I like the idea of the Grab being up against the tree and how that would all work....... Thoughts?

See the pic of the "micro-loop". That's what I was thinking but replace the saddle side d with the Pinto in my system.

Pulley Saver?? Picture, please.

Yeah, I figured some one would ask. My original post was pretty poor. I will try and get some pics of my idea up soon.

Here is my poor-mans pulley saver. I would take the Pinto and the green sling in the pic and girth hitch it to the Micro Grab and use that to adjust the length instead of a prussic. I will still try and configure it that way and get a pic.

Why the micrograb? That looks like a fine set-up there, with less metal, therefore lighter weight and cheaper achieving the same goal.

Eric, how old's your kiddo? Name?

I want something that will adjust easier. I mostly use that fs on removals, especially spruce and pines so the prussic gets pitched up pretty bad. I was thinking a mechanical rope grab might be smoother.

The pic is of one of my twins, but I am not sure which one. It's either Sam or Max and they are 18mo now. They sure like shiny tree climbing toys.

Don't we all! Can I get an Amen?

Amen!

AMEN!

I see, Eric. Would a piece of rope adjust better than the pitchy dyneema sling? I can see that it would be problematic. A rope grab is very good for pitchy stuff, just seems like its a funny application choked right up against the tree was all I was thinking. Do you think it would cause any funky leverage on it when its choked around the stem.


Amy and I were talking about how little white, bald-ish kids, like Dahlia and our friends' baby and you son, all look the same for while, except she doesn't know how to use her fingers as mining tools, yet . I forgot you had twins. Kinda thought he is a he, and toddler-aged.

OK, so the term "pulley-saver" is one I had to look up. Got it now, just a type of frition saver, and I have seen them in the cataogs recently but the specific name didn't register.

I think a MicroGrab would do alright, but it sems likeyou would have a slight chance of the cam eye bearing on the tree and allowing slippage, though it should re-set as soon as it moved a bit out of direct contact.

I personally don't care for that type of FS...too little friction at the tie in anchor for my taste, creates a few functional difficulties at the hitch. And do you ever have trouble with the pulley tether allowing rope twist to turn it a time or two and creationg drag between the legs of your lifeline?

I actually have a prussic made out of StaSet on there right now. That pic is old and I never liked that sling as an adjuster. I was thinking a rope grab would work well because of the way it works on lanyards, especially on pitchy ropes. I am not sure about the leverage thing, I was hoping someone here would have some insight on that subject. My gut feeling is that it would be fine.

By the way, if anyone's kids need help learning how to dig for gold, just send them my way. I must be a good teacher since all of my kids to that very well.

I actually agree with you in most situations. Most of the time I use a ring and ring except for working on a spar. For deciduous trees, I prefer a ring and ring adjustable but for evergreens I like the pulley saver because it keeps the rope totally away from pitch.

As to your question about drag, I have never noticed that happening, but I only use it to descend short distances when moving to my next blocking position. Yesterday I did descend about 25 or 30 feet while I was waiting for the power company to de-energize the power line. No problems with drag on the way up or down.

Your best bet is to just not work in pitchy trees. You should find the ease of adjustability will drastically increase.

Otherwise, good looking PulleySaver!
