Title: cable splice ?
Post by: backpacker on November 01, 2012, 02:24:39 PM
Afternoon: I wonder if anyone has a web site to suggest, or has instructions for putting a long splice[ eye] in a 7 strand 3/8" cable, have worked with 4 and 8 strand rope before , but getting lost with this stuff.
Its used on a norse winch, and instead of knotting the end, i want to use the eye/swivel feature of the orginal cable [until it broke off:(]
tks

You sure that isn't a standard 6x19 right hand lay cable? Is the center strand very ridgid and have a slight screw to it? Meaning the 6 wind around the center. If yes to this I think you could just put a Flemish eye in it. Unravel about 12" or so and pass the four strands back to the 3 strands in a loop configuration. pull tight till they interlock. Then weave the strands around each other. They will normally fall in place. Depending on the size of eye determines how much cable to unravel. This will be at least as strong as the original run. Gather the loose end and either put a clamp or make a sleeve you can hammer tight to the cable to protect from any burrs. Dad and i have used these around here for 40 years or so no problems. Hope this is what you were looking for. Have a safe one. Chuck

Another Norse winch owner. I like mine. I have the 450,the one with the swivel  butt plate. We used that poor thing hard. It lives a life of ease now,just getting my firewood.

Whenever I have to do more than just a farmer's eye splice, which should be secured with a couple of bulldog cable clamps, with the clamp's eye over the Standing part of the wire, I refer to worksafeBC's manual on splicing. It has all manner of splices used in logging and the marine industry.
You can find it online in its entirety, for free at this address.

WorksafeBC's online library is worth a look with all sorts of information on logging, yarding and falling operations.

ok i guess i have to read and print a few instructions off to carry outdoors, all good stuff, tks guys.
and yes it is a center core with 6 wraps, the old knot in the end just doesn't look good:)
and the clamp termination would be a problem for sliding the bells along it, i am sure it will work out now.
a rainy day in the barn excuse to get away:)

Can you use a preform on that cable?
Utilities use them for joining and terminating.
They go on in less than a minute and are extremely strong.

Hey folks, seems to be lots of people using cable to haul wood. Had to tune up the rats tail so I thought I would add a couple of pics. Maybe there are better techniques out there but for what its worth   ;D

 (https://forestryforum.com/gallery/albums/userpics/12754/rats_tail_1.jpg) set up,tape cable

 (https://forestryforum.com/gallery/albums/userpics/12754/rats_tail_2.jpg) Cut,old knot on the right

 (https://forestryforum.com/gallery/albums/userpics/12754/rats_tail_3.jpg) reverse sliders

 (https://forestryforum.com/gallery/albums/userpics/12754/rats_tail_4.jpg)  attach to bumper tree,snap on vise grips

 (https://forestryforum.com/gallery/albums/userpics/12754/rats_tail_5.jpg) give it a tug

 (https://forestryforum.com/gallery/albums/userpics/12754/rats_tail_6.jpg) takes about 5 minutes.  :)

That will work. Do you torch the end in to a glob afterwards are leave it exposed? Question as I have never seen that before all the slide parts and just one cable end/knot. How does that work?

   If you notice a locker off a cable chocker is used just before the knot. This is the chaser, used to pick up straglers. It prevents the bells from coming off. This is an on site in the woods repair. I suppose you could use torches or a portable grinder but I have never felt the need. This is out of a fear of fire.  This is just how I was taught and seems to work around here.    :)

This is the same way i retied the mainline for 30+ yrs. I had trouble with a single knot pulling though or coming untied, so i used a figure 8 knot. After a few turns I'd take the hammer an use the edge of a fender or double bit axe to cut the burs off the end of the knot. When doing this, absolutely have safety glasses on.
I used the same slides with cable chokers with spring pins to keep from losing any chokers.

Evening: Did some thinking on this splicing a eye in the tail end of the mainline, and realized something... the bells are going to slide ok over a splice, BUT when a load is hooked on, they will be pulling against the exposed cable making the eye for the end hook.
which will either crush the eye or cut it off, so i am back to looking for a thimble and insert design of termination.
One that when the bells are pulling against it the [pass the loose end through to make a eye]the insert is pulled into the thimble and tightens/gripes the cable accordingly, once tightened/squeezed enough it stays where it has been set.
Going to check the web for such a item.
tks for now.

Check out Esmet safe-line clamps One source is AW Direct.

You need a babbitless choker knob, you can probably get one where ever wire rope is sold.

Afternoon: I found a outlet from the esmet site in this area, and all good to go, until the "minimum order" clause came up, it does look like the safe line clamp is what i was looking for, but not at this time, double the price to get one....
doing the direct e-mail and re-source a supplier from esmet.
I see where Haywire woodlot mentions a Babbitless choker knob? any site info as to what they are or look like, better to know what i am describing to the cable dudes first:)
that sthe latest of a simple idea
tks guys.

Labonville in NH has ferrules and wedges for 3/8 cable. $9.95 each on their web site.

Evening folks: Got a solution on its way from labonville, once the Canadian connection was setup by the company tech person, going to try the ferrule and wedge product, tks for the help and results to follow.

That method of doubling back is pretty easy to do .Best put the thing in a big vise to hold it .

On the end termination of course a pressed sleeve probabley works best .I've seen them done with a Crosby type clamp as well as tie wire served though which must have worked .Fact I've wire served them myself a time or two and they never pulled out .--Hint wear some stout leather gloves because wire rope can eat you up .

does anyone sell ferrules and wedges for 1/4 cable?  I use 1/4 on my arch.  Did an internet search and couldnt find any.

Try Mc Master -Carr ,they have about everything else .You can do 1/4" just like I talked about .

Fact just to show a wise azz millwright at work I could do ,so I did about a month ago .

Little wire rope like used on cable come alongs or to raise garage doors they just use either an aluminum  or copper sleeve they crimp .It won't pull out .Fact the 14 high feet by 16 wide doors on my shop are done that  way and none have failed in 16 years .I did those little cables myself using a Burndy nicro press made for crimping terminals on electrical wires .

I use the aluminum  on 1/8 and 3/32 cable which I just hammer closed.  buy them from trapping supply places but they dont carry larger ones.
