Brazing wire rope?

Apr 09, 2005 7 Replies

Is there any reason why I can't (shouldn't) make an eye in wire rope by brass brazing?


Yes. The combination of the stiffening from the flow of the braze and the heating of the wire will cause it to fail a short distance from the eye.

I tried this many times before I got the tools for crimping nicopress fittings. My method now is to use an insert in the eye (old age - can't remember the term) and a nicopress fitting. I then put two or three layers of heat shrink 50 to 100mm long over the nicopress and adjacent wire to act to avoid sharp bends at the fitting.

Thimble.

Sleeve.

I have managed to assemble a rather complete collection of nicopress tools for 1/32" cable to 5/16" cable.

Funny thing is I made a very simple set of nicopress dies for my hydraulic press that covers the same range and does it much faster.

See it doesn't matter what you use to swage a nicopress sleeve as long as the slip gauge clears it.

Go down to 6-26.

No one can do an eye splice anymore?

Leftwingers are like pond scum. They are green, slimy, show up where they are not wanted, and interfere with the fishing.

Second that suggestion. Do a search on Flemmish eye. Easy to do. And I believe required by the U S Navy for slings handling explosives ie reliable.

Sorry make that Flemish Eye with one M. I did google on Flemish Eye and found two versions. One for monofilament fishing line, obviously not what I meant. The other for wire rope were all by manufacturers selling sleeves for a swage to finish off the ends. Putting a swaged fitting on is nice, but almost all the strength is still there without the swaged fitting.

If you are using the wire rope around salt water, you want to use a sleeve that is the same material as the rope. ie don't use a bit of copper pipe as it will cause the steel to rust more quickly.

For a number of applications of 1/32" cable, including RC model sailboat rigging, I made my own "nicopress" fittings from a 1/4" long piece of

1/8" Al 5556 TIG rod with an axial hole drilled with a #56 drill. Lube with d-limonene for drilling.
