DMM Pinto Pulleys and Impact Blocks Now in Stock!
browncow replied to Honey Bros's topic in General chat
Does anyone know if a spliced eye in 11.7mm double braid will fit through the small pinto? My mate has ordered one thinking it was the pinto rig and now he is a bit worried. -
From playing around with my ropeguide it seems to me that when you have the prussik attached individually to each side of the pulley, then when you move to the left the right leg takes more tension and vice versa. This doesn't appear to be a problem when you have the rope looped through the two eyes with a spacer. I think this uneven loading may be causing the sheave to rub on the cheek and cause the wear people are getting. If anyone on here knows of any pinto's that have this wear on the side of the sheave and have it set up with a loop and spacer then I will stand corrected. It wouldn't be the first time:biggrin:

classic

Woah, definitely sounds and looks like the bearing has collapsed. Has it smacked into anything hard on retrieval? At least the becket is rated if for some reason the sheave came loose before you noticed all this.
-
'I'm gonna need a pull on this one' 'yeah give it a tug mate' I'll just give the bar a rub and I'm ready to go' Frankly, its a gay industry when you look at the lingo.

I posted some pics on here somewhere of my pinto which had the shackle sucked up. I have a witchard (spelling) shackle and if the 'pin' end gets sucked in it results in a line around the sheave just off centre and also damage to the side of the sheave caused by the handle of the pin. I have been able to manipulate the shackle to sit just right to see how this damage may be occurring. I now have a longer length of rope to where the shackle sits and a heavier stopper knot and no more problems there. Edit - post 13 of this thread shows the damage to my pinto

liam88, I think you are right about the bunching. I was aware of that and did milk it a bit but obviously not enough. I think if I put a biner through the eye and tie it off to something I may be able to milk a cm of cover into the rope. I used a prussik to slide along the rope to bury the eye during splicing. I guess this will work just a swell to unbunch the cover strands.

The needles I have snapped were on old 16 strand rope that was hard as nails. Maybe I am rough or seeing as I live in Asia maybe they are crap china-made needles:biggrin: I have one of those flat needles like the one in your picture but haven't used it as I was afraid it was a bit too 'chisel-like' and may damage internal strands. Yes I am paranoid:001_cool: Is 'low-load slippage' more a problem with say 16strand constructions and class 2 double braid (straight bury) rather than class 1 double braid. I cant imagine the splices I have done on my blaze going anywhere under low loads?
-
Cheers, I was going to whip it closer but am down to my last needle:biggrin: and really didn't want to snap it. I guess there wouldn't be any issue with putting another whipping closer to the eye as well as the existing whipping?
-
Yeah its funny, the first 4 or 5 splices on 16strand I did, I threw away after cutting them up to have a look, then as I got better I started using the splices and trusting them. With the blaze it all went so smooth I am happy as larry to climb on them all day long. Loads of fun making rope tools - I'm hooked. Cheers for ya advice Drew on those first few I did.
-
I finally got the time and rope to have a crack at a class 1 double braid splice. I wanted to make a lanyard up so I could try the cinch I have had sitting around in my bag of tricks and which doesn't fit on my current lanyard. I have been splicing the **** out of 50odd meters of 16 strand I 'retired' when I caught the splicing bug and was suprised to find the class 1 splice quite easy in comparison. Heres a couple pics. Yale Blaze eye splice on each end (1 end yet to be whipped). Stoked with the way it turned out and can't resist posting a few pics.

woah, stop press, Drew just posted a pic of a rope without a splice! Nice set-up bro, I seem to remember you setting this up for me for my first climb on a vt/hitchclimber.

I had a bad experience yesterday with my home-made rope-guide. The first pic shows the damage to the sheave on the pinto pulley, the second my RG setup/footlock prussik/srt leg-loop, and the third a close-up of the retrieval shackle. Basically I was packing up my gear and noticed the wear on the sheave. It has sharp edges and a burr or two. The only explanation I could think of is that the shackle got 'picked up' by the rope on a fast descent and lodged in the pulley wearing the sheave as it spun. There appears to be some wear on the shackle although its hard to tell. Has anyone seen this before? I have been meaning to splice up a new dedicated RG out of heavier 14mm rope and maybe the extra weight of the rope at the shackle end would stop this happening? Or maybe just a freak accident. Could have resulted in some rope fairly substantial rope damage I guess. I think a bit of wet and dry sandpaper should have the sheave fixed up. Should I paint it to prevent rust or will that just wear off?

Have you ever been there when a tree has failed naturally ?
browncow replied to Arbgirl's topic in Tree health care
Great thread. I would love to see a large failure as it happened. Seen plenty of branches coming down in storms but no whole trees. I did see a video of an arborist in Wellington NZ who scarfed a large pine or mac and then was getting ready to put in the backcut when it failed at the roots I think. Would have been plenty exciting! -
I bought the Pinto 'rig' recently and am using it for a rope-guide. It's super smooth, takes a spliced eye easy and have not had any probs retrieving yet through the choked eye. It seems to 'flip' up and through the eye easy (the eye is stiffened). It is quite big though and I am keen to see if the smaller version also takes a spliced eye?
-
Yep I agree. How long has that requirement been around for in UK, Is it complied with/enforced? Do smaller companies find it overly onerous?
-
Yep, inline anchor on SRT. Pain in the arse on a lot of jobs but if your ground-crew has no climbing gear/climbing skill at least they can lower you out (maybe).
-
Although not always feasible you can also work DRT off SRT line tied off at base. Then you can also be lowered out of the tree (hopefully). This is often not practical though, especially in rigging situations where it can get messy having all these ropes to look after. I have spent way too much time being the only climber (and also the only person sometimes) on-site and as mentioned above, sometimes the best you can do is have the tail of your rope clean and tidy ready for an emergency descent. Cheers.

Running bowline with a long tail does the same thing. This would be ok, (comfortable) on a long stem you were snatching down though, (just a little gear intensive).
