If only there was someone on this forum who could help me  I have 50m chain (10mm??) getting slightly worn at the high use end. I really would like 100m, perhaps 75m. What are those chain joiners like? I was thinking buy 50m new nice chain from a reputable Nthshore supplier and then put the old chain so last out of the well. Thoughts? |

No one with any clues I know of but on the back of a ciggie packet I found this morning, it said - Like all products there are good, bad and absolute utter crap that should not be being sold. On the NZ market we have all 3 of those when talking the 2 piece chain joining links (aka 'missing links' by some who tend to have US accents). At the good reliable very well proven made in the US (due to a dude called Trump*), batch tested we have the 'Crosby' branded ones. Grade 30 fitting and once fitted as good as the links either side. One wee niggle is being US made they cost but then as a dude said last week 'What's it worth to keeps me off the rocks while letting me sleep in peace'. Then we have a few no names that tend to come from the east. Some are good some not so much, it is hard to tell unless you are an oval shaped metal tragic like some. I'd be asking some hard questions while watching closely for facial twitching and other such tells. It's hard to give any guidance here as there is little to pin comments too i.e. the lack brand name or other uniquely identifiable things. If you run into any do feel free to email/message me with 'how it was described', being sold by who and the price. I can often get an idea from that. Then we have the ones that I have personally tried to get taken off the market in NZ as they are so weak they are fucking dangerous and I will be more surprised if none fail leaving boats on the beach by a huge margin over any failing, I do fully expect more failures. On the NZ market these are Stainless Steel. If you buy one you'll have been conned, it is that simple. If you buy one after reading this your a muppet and please if you see me at anchor put yours down at least 1km away so I don't hear your kids screaming as they are bashed on the rocks, thank you. But the ComCom is as effective as dunny paper in a cyclone, less actually. We had a dude on only last week who was proud as punch he brought a SS link from a name place and fitted it to his chain, 8mm. I told him what I thought of the links, he went a little pale so I said I'd test it for him if he liked, he did. So we put the chain in the bed and went for it. Shitty 8mm chain will get 2.5t generally, it's supposed to be 3.2 minimum but not everyone knows their products. Bang, the new unused link failed at 772kg, which is the highest we've seen a 8mm break. We did a 6mm and 440kg break, 6mm should be 1800 minimum. A while back I approached a few including the biggest importer of them and said 'dudes WTF?' they said 'Hmmm, where did you find these dodgy numbers?'. 'Your own website muppets'. 2 days later management ring me to tell me they have solved the problem, they have taken the specs off their website...but as still selling the shit. Unfuckingbeleibvable but then it is an outfit that exhibits poor product knowledge regularly. Suss the price, if you are having to pay $30 for a branded steel one but only $4.95 for a full stainless steel unbranded one ask yourself why. After dude last week was in I purchased a range of SS size and we'll put them to the test next week along side steel. If I can't get them off the market at least I can try and help stop people falling for the scam they are. I shall post the results here. So Yes you can do what you are thinking very safely without strength lose AS LONG AS you follow a few basic rules like buy a good link and use G30 chain.
* - Crosby is a big lifting material manufacturer based in Canada but supplies huge amounts worldwide, it is a 'go to' name when Specifiers are writing tenders etc and it supplies the US Govt LOTS. It had a big foundry there which was old n tired. Then in rolled the Trumpster who quickly said to the world 'if you want to supply the US Govt more then you have to make more shit in the US'. So Crosby built a new state of the art foundry in Texas, word is it cost them best part of US$300 mill and employs 200 people.

Cool great info thanks GC.
Sorry I might have missed it but what’s the NZD$ price of the US unit you recommended / trust / sell yourself for 10mm chains and also for 12mm chains (as I’m interested in doing similar).
And last Q: presume they run through windlass totally ok with no snags?

I believe your grey matter is like a hard drive, it can only hold so much. As my business is all numbers I've stopped trying to remember them all as doing that risks pushing the good/fun shit out the back to be forgotten forever.
So the $$'s, I'm in rural so gonna guess 1 small heifer and a truck of lime for the race. I'll suss on Monday, sorry Tuesday, I'm shopping for a new mower Monday.
Yeap while the US ones are imperial, so can vary a mm or 2 from our metric chains, one link is fine thru the winch. Get a series together and you will have issues.

Many thanks. I was scrolling your site looking for the link before I posted and was suffering from poor searching. Could have been Chardonnay related. 😂

Your website seems to be playing up too. When in the store if you select chain you get other stuff etc.

Thats a new site that went up last week but having issues getting into it. The computer industry uses the term 'seamless' often but they have absolutely no idea what the word means.

What are those chain joiners like? I was thinking buy 50m new nice chain from a reputable Nthshore supplier and then put the old chain so last out of the well. Thoughts? Just a thought, do you really need that extra chain? CZ has 100m of GO30's woggy best (the old Camry sure sat down on its springs when we loaded it  ) and in 7yrs of cruising including 2 trips to the islands the only time the 50m mark has seen the light of day is when I end for ended it. You don't want any more weight in the bow on the Riv at approx 1.5kg/m. As a compromise you could carry an extra 20m of chain and one of those fancy joiners and leave it in a plastic sack (with some vegetable oil sprayed over it) in the bilge where the weight would have the least impact. |

Good suggestion. I have had all 50 out during our delightful summers recently. Nothing like cruising during tropical cyclone remnants 😂 Already dropped about 70kg off the forward deck swapping to a true kit dingy. |

Already dropped about 70kg off the forward deck swapping to a true kit dingy. Saw that and instantly thought 'He fell overboard' but then I saw the 70kg and changed my mind  8mm 1.4 kg/m 10mm 2.35 kg/m No!!!! Stainless steel weighs the same as do the high tensiles. The number who think SS or G70 is noticeably lighter is huge, no idea where they get that from though. Purchased another mower today, one that will cut a 2.5m wide swathe at 30kph. I see us having lots of fun together. For the rurals its a Maxam 2500 but a swinger unlike most they sell which are fixed behind the tractor this one folds back for transporting etc. So tomorrow I'll stretch a few of the SS links next to Crosbys and lets see how right I am. |

The farm I work on has a Berti 2.5 that can slide from side to side on a hydraulic ram , awesome for mowing along fence lines and preserving gate posts ! . It goes on the McCormack 120hp and will mow anything right up to gorse. I wouldn’t do 30kph though the tractor maxes out at 35 full jandal and the air suspension seat makes it hard to steer in a straight line on rough ground at speed . |

While I'm told 30kph I know if I try that speed I will get exactly what your describing, any bumps and I'll be fired right out of the seat and probably the paddock as well. I'm on a 80hp orange number, complete with twin speakers, each featuring a 250mm bass and optional LED mood lighting. I've been pimping my ride

Ok so we put the SS Clinks to the test today. We installed them as you would in the matching chain size then dropped them in the bed. ALL failed to meet Proof Load before changing shape. Proof Load being 1/2 the break load and a loat at which links are not allowed to change shape. So we went on to the destruction test. 6mm base grade, Grade 30, chain breaks no lower than 1800kg, the 6mm SS Clink was totally destroyed at 774kg. Huge fail. 8mm G30 chain 3200kg, the SS clink tore aspart at 2492kg. This was the best result the links got but it was still totally shit. 10mm G30 chain 5000kg, the 10mm SS C Link totally fucked at 3872kg 12mm G30 chain 8000kgm, the 12mm SS Clink totally bugger at a freaky low 4698kg.
So the 6mm link was shit. The 8mm just crap, the 10mm only as strong as 8mm chain and the 12mm C link was abysmal well below 10mm chain loads. Basically they would easily be the weakest link in your rode and worse being SS they are likely to degrade bloody fast as well.
Note here I am talking about the Stainless Steel 2 piece links only in this post. We brought them from a nationwide well know Stainless fastening mob but they are being sold in chandlers and being sold as 'strong as the chain'...mind you some of the chandlers are selling shit chain so maybe they are bullshitting even though they don't know it.
I'll do some Crosbys tomorrow. I would have today buy we have a 55fter with a twisting chain issue that I've never seen before nor can explain why so we went boating to try and find out. I've seen some WTF's before but this one is on another level............... and it's now become personal.
