NER V12 vectran single braid

I also prefer the security of locking brummells. I would probably favor that over a straight bury. I like the overlap to keep things round under load. I think I'll try some of that yellow stuff!

I have heard that ceramic knives work well on the high mod lines. Has anyone tried this? I wonder if they make ceramic scissors.

i took a few splicing classes at brion toss' shop and they have a special group of implements used for the evil high modulus knife-killing fibers - the one i remember was a ceramic paring knife that lived in it's own box. got scolded for trying to cut something hm with a knife.

i went out looking for a ceramic knife (since i'd dulled all my spyderco knives splicing..) and wound up with a ceramic/metal hybrid called ceratitan made by boker. took waaay longer to dull than steel - the disadvantage is that you can't sharpen it yourself, you have to send it in. also very spendy, though my guess is the ceramic paring knife brion had would be a bit cheaper. i don't remember seeing ceramic scissors, but i've wished for them too!

Kathy, I was looking at those knives a couple weeks ago thinking about getting one for the pops as an xmas gift. I can't find good info on them online though. How are the metal and ceramic hybrided? What is the cutting edge?

The knife I use for hm ropes is made by Kyocera. I got it free when I bought a $289 . kitchen knife . It's a simple thing with maybe a 4" white blade. I had to paint the top of it orange because I once put the back side of the blade against the rope and almost pushed on the blade full force with my thumb!

I've been very happy with the ceramic. I'll have to send it in to have it sharpened eventually, but so far it still seems brand new.

love

Can anyone tell me how long a length of Ice to use for a standard eye & eye? I am buying in bulk to make Christmas presents for some friends and am not sure how much to get. Thanks,

I use 68" for a 26" Ice Tail eye to eye (measured from bearing point to bearing point), 72" for a 30" eye to eye, and 74" for a 32" piece. There is a little left over from these measurements, but the excess makes it a little easier to do the crossovers.

Wow, I think you should get part of the kitchen and stuff to go into it
for THAT price !!

IIRC, Brion once said that folks seemed to prefer using cheap knives that
were continually sharpened (and worn down, hence).
Any feel for which of the hi-mod fibres are tougher than the others,
Vectran vs. Kevlar, Technora vs. Dyneema ?

*kN*
 
I've never noticed a difference in the cut-ability in all the high-mod fibers. That might be due to the kick butt blade on my ceramic knife!

That last line of Rich's post is worth remembering if you're going to splice something.

When I started splicing things, I wouldn't want to waste an inch of rope, so I would only cut the amount I needed, and nothing more. Then I'd find that I'd measured just a hair wrong, or the sling shrunk more than I thought it would...then now instead of wasting 4" of rope, I wasted the whole sling.

I'm happy to waste half of foot of rope on each sling now, rather than having to remake it now!

I had some of the yellow 16 strand hollow braid and some of the pink 16 strand hollow braid (don't know if there's a difference). The yellow tail was given to me spliced with a brummel similar to the one posted before.

Norm showed me how to do the straight bury with the pink stuff and I found that to be a much cleaner appliaction.

From what I understand, and I could be wrong, the straight bury would also be a stronger splice in the end, not to mention easier and faster (and more attracitve to the ladies!).

It was ok cordage IMO, one tail got covered in pine sap and another got slippery pretty quickly....

HRC (#1) then Beeline (#2) are working the best for this guy <--
 
Yes, a straight bury is STRONGER, a locked brummel is more SECURE.

For climbing applications where strength isn't the biggest concern, I prefer the locked brummel (which, now that you mention it...Norm taught me!)

There are several things to keep in mind. Dyneema, a derivative of polyethylene, has an extremely low melting temp, 297*. A poor choice for friction hitch applications. It has a very low conductivity, a great choice for working around energized lines.

My personal experiences:
I use technora for friction hitch eye & eyes and have been for a number of years, exactly I don't know, but at least 8. It will take tight bend radius turns much better than kevlar. It is very resistant to heat and petroleum products.
I use dyneema for spider leg slings for crane work and rigging when working around energized lines. Once put to use, it gets a 'fuzzed up'. The fuzz helps protect the inner fibers from wear. I have two 1/2" spider leg slings that have way more than 100 crane picks on them and they are still in excellent shape.
Vectran is relatively new to our industry. I have tried eye & eyes with it, but found it too slippery. For the money, technora is only a few cents more (less than 1%) and has higher heat resistance.
Melting temps: Technora 900*, Vectran 625*
I would like to see more Vectran data from our industry before I use it in rigging apps.
Dyneema and Technora are the fibers I use. Each have there limitations and advantages.
