Dyneema Rigging

[Russ]

Well, I suppose Tom would be a good one to have on board too -

Maybe someday if I become a really rich billionaire guy I will buy a huge giant sailboat and i will pick my crew from people on this site.

Agreed. The knowledge these guys offer is so valuable.

So I guess I should ask an expert before trying to buy these tools. Actually, I don't trust myself to swag it right. But for $28, it might not be a bad idea to buy one in case of an emergency.

Just to clarify that this tool from west marine is for nicropress and not swagging. You can get swagging tools just like this but not rated for standing rigging (rated for lifeline fittings) I have both the nicro and swag presses like these and they do work very well but are slow. The press I linked is rated for swagged fittings for standing rigging for $140.

I'm not quite sure what you're saying, but the OEM standing rigging used Nicopress copper ovals.

The only swaging I'm familiar with is either Nicopress type oval sleeves, or large roller-swaging machines for big rope, like 2" dia boom pendants. I know small swagers are used for things like the turnbuckle fitting on the bottom of the forestay, but I know nothing about them, and therefore didn't even think of that kind of swaging.

Here is a lifeline hand swagged terminal:

The wire goes inside the fitting and is crimped inside the fitting (similar to rolled). Two variations when purchasing, machine specific or hand specific.

Nicropress (oval) fittings require a loop back through the fitting.

You could go with either a swagged (much cleaner) fitting but would require some more parts to convert the OEM rigging. If I still had the M I would go this route with turnbuckles. Much easier to fine tune the rig if you're not trailing all the time.

Take a look through Johnson's catalog and website http://www.csjohnson.com/(go to Page 29 for hand tools). You get a good idea of whats out there and how its supposed to be used. For instance the hand swagging (bolt cutter style) will produce a fitting rated to 65% of the wires breaking strength, not so much for the bolt/compress style tool made for lifelines.

THE REAL QUESTION IS: Do those ships use dyneema rigging??

[yukonbob]

If I could afford either of those boats I don't think I'd really care lol might as well be gold plated rigging

There are quite a few cruisers using dyneema as standing rigging though. Easy to splice, easy to store. UV's the big killer with it. Not a bad idea to keep a length of it as an emergency stay though.

Just go to dyneema. No special tools required (other than deep pockets).

My rigging is still on good shape, but when it gets tired I'll be considering dyneema. My cousin loves his, and he does a lot of trailering.

Besides, it looks really cool... kind of retro and high tech mixture.

I don't know why they can't make Dyneema with some UV protection built in. Spray it with sun screen????
The sun is really really strong at our altitude. I use some polypropylene for some applications (dinghy painter) and the sun really eats it up.
