dynex dux

[Brian Duff]

So some of the projects I have been working on using dynex dux are comming together finally, and I am excited to share them with you all. here are a couple of teaser photos, there will be more as I wrap up next week, and then sailing results.
Lets hope this stuff works as advertised - we have been pretty conservative in scantlings so maybe these are not the best 'test rigs' but I am not selling tests, only solid boats.

On the wooden rigs we only supplied the rigging kit, the aluminium spars our my design and inhouse build. the upper shroud tangs are not pin'd but we mashed up the exposed threads so the nylocks will never come off... every other fitting is pin'd.

more as we finish up

Dear Brian, and Brion,

Spurred-on by your posting of pictures of the Dynex rigs you are doing, I have attached some photos of the re-rig I carried out with Dynex on the 1936 designed and built "LANDFALL" - S&S design #54. She was built in Tasmania and now calls Sydney home.

I have worked closely with Mike Strong of Strong Rope here in Sydney for a while now, developing techniques for getting this material to a point where it exibits repeatable characteristics when incorporated into a stay, with promising results.

I chose their Dynex product with overbraid . Strong Rope also supplied all the other hardware - thimbles, turnbuckles as well as the serving material.

As you can see, being a bit gun-shy of the stretch caracteristics, I allowed for quite a lot of adjustment on the caps and less on the lowers.

I was actually too clever for my own good, because the Dynex stretched a LOT less than I allowed for with the results showing in the fully tuned lengths of the turnbuckles. I was expecting to tighten the screws all the way up and then have to shorten and re-splice the bottom ends. In reality, the stays have tensioned just like Dyform and have held their tune well.

In subsequent rigs I have allowed the normal 2/3rds to 7/8 open on the screws and made to that.

"LANDFALL has been happily sailing around for nine months now with no ill effects and a marked improvement in her sailing abilities.

As Brion says, it seems we are on the cusp of a renaissance in affordable fibre rigging as a direct replacement for the usual 1x19 and swaged ends. Everything on LANDFALL fitted into the existing tangs and spreader tips without modification.

I have been recommending this system to most of my re-rig customers with about a thirty percent take-up rate.

I will keep you posted.

Regards,
Joe Henderson.

that looks great, I like the serving of 1.75 dyneema line.

I tried the deadeyes colligo is using on this schooner.

I didn't expect turnbuckles would work.

I'd love some more photos and consult from you.

could you email me ?
