In that scenario, my idea of adding a safety margin is using TWO ferrules to hold a hard-eye. Ferrules cost a quarter or so, not a hundred or so. Hard eyes under a buck. All the same, I have a hankering for those bolt up terminals, and I like the idea of the Suncors, even if I can't beef up their reserve strength, AND they cost way, WAY more.... Brian W If you are being cheap why not learn to splice cable. A properly spliced cable will be about 90% the cable strength and cheap. All you need to splice it is an ice pick. Cheers, Bruce (bruceinbangkokatgmaildotcom) That is no doubt a fair question. There is nothing much cheaper than a - what is it called? - a fidd? Splicing rope is something I can do and get satisfaction from, in moderation. Moreover, I get the sense that a well-done splice is about as strong a union as can be obtained. But splicing wire is (to my mind at least) like knitting a sweater - something I could do, even have done, but I used a knitting machine to do it! With just a fidd, it seems (in the abstract) like wrasslin with a pig. ;-) I know, It's all in the mind... BrianW |

Usually just a ice pick filed a bit oval. Cheers, Bruce (bruceinbangkokatgmaildotcom) |
