erice 732 Posted May 30, 2016 Share Posted May 30, 2016 hi all,with this crappy weather this weeks sailing time became boat upkeep some of the bronze hanks on the old racing jib have eaten their eyelets so decided to have a go at moving them the move went well but haven't tried closing the hanks up again yet suspect they might break toying with the idea of slipping them off again and trying to anneal them first the question being what is the best way to anneal bronze with a quick quench in water like copper? or a very slow cool in ash like steel? sure google with know but anyone here with experience? edit To soften (bronze) , it should be brought to a medium red color, (held for 1-2min) then quenched in water to cool quickly. I would be careful not to overheat it though—some bronzes will suddenly go from solid to falling-apart when hot. Quote Link to post Share on other sites
Black Panther 1,589 Posted May 30, 2016 Share Posted May 30, 2016 Throw them away. If they don't break they are weakened. Quote Link to post Share on other sites
erice 732 Posted May 30, 2016 Author Share Posted May 30, 2016 throw them away! next you'll tell the holes in the jib mean it's toast too Quote Link to post Share on other sites
Freedom GBE 27 Posted May 30, 2016 Share Posted May 30, 2016 Has anyone tried soft shackles? Quote Link to post Share on other sites
erice 732 Posted May 30, 2016 Author Share Posted May 30, 2016 ^ they did turn up in my research so at least someone, somewhere has seemingly used them successfully on a side note after studying carefully the chafe on capricorn's mainsheet block dyneema loops + traveller have rotated all loops to move chafe area away from boom corners and have shortened the dyneema looping on the traveller, by adding another loop to also move the slightly chafed areas away from the chafe causing edges as always it's in the good book Job 12:18 New International Version (NIV)18 He takes off the shackles put on by kings and ties a loincloth[a] around their waist.

ex TL systems 63 Posted May 30, 2016 Share Posted May 30, 2016 just warm them up a bit and prise them open, when I did it none broke on re closing with a soft mallet or block of wood, although new piston hanks aren,t all that expensive if you can get them wholesale, When I say warm I just mean 30 or 40 degrees or so.

rigger 47 Posted May 30, 2016 Share Posted May 30, 2016 Another method if they break - if there is enough material left is to drill two holes and seize them on. Worked ok on some larger ones many years ago - they were $20each at the time. Quote Link to post Share on other sites
Pumbaa 9 Posted May 30, 2016 Share Posted May 30, 2016 I can't see what you have to lose, you've already bent them once so there's already damage that can't be undone but I don't think the damage would be significant for their use either. You haven't opened them right up, just put them back in and tap them down again. What is the worst that would happen any way- you'd lose 1 or 2 hanks in a race, they're just jib hanks, you could probably sail an entire race without any in at all. You're not lifting anything heavy or a person and If some do break then you know which need replacing. Quote Link to post Share on other sites
erice 732 Posted May 30, 2016 Author Share Posted May 30, 2016 Vorpal Blade, a sailmaker, has pointed out that best to use are hard (stainless?) 'spur tooth' grommets and make sure any repositioned hanks stay below batten pockets or they will snag the hoist + drop thanks Bill so just went ahead and tried to anneal the hanks by boiling for a few minutes (probably pointless) and then heating to cherry red.....................if correctly annealed it's possible to reverse the 'crystallization' that happens to work hardened copper alloys Quote Link to post Share on other sites
John B 106 Posted May 31, 2016 Share Posted May 31, 2016 How interesting. ,I've been doing the very same job. I lost a few opening them....the rest look OK. I heated them up to 40 degrees by swearing at them. Always helps. Quote Link to post Share on other sites
Vorpal Blade 89 Posted May 31, 2016 Share Posted May 31, 2016 Reheating them, and annealing them, seriously. How much time are you wasting doing that when a replacement is under $10. Quote Link to post Share on other sites
erice 732 Posted May 31, 2016 Author Share Posted May 31, 2016 the witchard hanks are nice 1 hand use, no piston to clag up http://www.fostersshipchandlery.co.nz/afawcs0160483/CATID=383/ID=6234/SID=164918748/WICHARD-BRASS-SAIL-SNAP.html this style reusable Quote Link to post Share on other sites
Vorpal Blade 89 Posted May 31, 2016 Share Posted May 31, 2016 The are great until the gennaker sheets catches in them when you gybe and have left the jib up. Seen it happen! Quote Link to post Share on other sites

RushMan 31 Posted May 31, 2016 Share Posted May 31, 2016 Did Doyle announce a new soft shackle system recently? Quote Link to post Share on other sites
Tim C 23 Posted June 1, 2016 Share Posted June 1, 2016 I've used the Wichard hanks on Pulse for 14 years. Never had a halyard or sheet catch them. I have reused about 2/3rds of them on replacement jibs, without heating them or anything. Especially good for storm jibs, staysails etc that you don't use all the time, as the hanks remain reliable, unlike pistol hanks. Great to load at sea, by smashing them on the head stay one handed. A completely underrated bit of great, simple kit... Quote Link to post Share on other sites
Black Panther 1,589 Posted June 1, 2016 Share Posted June 1, 2016 I concur. Quote Link to post Share on other sites
waikiore 399 Posted June 1, 2016 Share Posted June 1, 2016 The Swedish hanks shown are what was marketed as NZ style hanks in Europe- referring of course to the Murray hanks made here for years, the European ones are not made of the same metal as the old Murray ones though -which could if carefully prised open be used again and again. I too have experienced the wichard hanks coming away from the forestay in very unpleasant conditions (flogging) and seen them hook other halyards --very tricky.

ballystick 72 Posted June 1, 2016 Share Posted June 1, 2016 How about a variation of these, could be attached permanently to the jib and cheap too, Quote Link to post Share on other sites
RushMan 31 Posted June 1, 2016 Share Posted June 1, 2016 Found this on another site, made by Doyle apparently Quote Link to post Share on other sites
