Stainless Steel Ferrule Crimping

[Ian_Rob]

I want to make up a couple of lengths of 3mm stainless steel wire with loops at the ends using s/steel thimbles secured them with s/steel ferrules. Available ferrules seems to be lozenge shape. Will my hexagonal battery crimpers that are supposedly rated up to 10 tons, give an acceptable crimp?

I have used an 8 tonne hydraulic crimp to make slings from 6mm wire, but used copper ferrules. They were tested to three times swl.

NO to the idea of battery crimpers.
Stainless wire is usually made up with stainless thimbles and copper ferrules. I use a 20 ton press , but that goes up to 5mm or more.
Unless I have missed something, never seen ss ferrules.
The swage blocks need to be the right size, not a guess with battery crimpers.
You say lozenge shape? Actually a sort of flattened oval. Room to put the two wires in, then swage to round.

Have a look at S3i 's web site. They can do this for you at a reasonable price, or supply the bits.

PS, if you can find or make the crimp blocks, maybe your battery crimper woud do. But seems a fuss for four ends.

At 74p each I say buy a couple and try it. Proof test to a load in excess of your requirement. Pretty sure mine is a 16 ton one and it will easily secure 3mm s/s terminals and considerably larger copper talurits. Do your crimps really need to be stainless? It is not normal marine practice.
