<p>I have found that the dyneema doesn't stretch that much: also is kinder to the main and mizzen on my boat when reaching or running before. It does need tightening now and again.</p>
<p></p>
<p>As I made my own deadeyes, it didn't cost much.</p>
<p></p>
<p>I am currently considering a moveable dyneema forestay on my mizzen mast on the 31' . I picked up some 8mm cheaply so what-the-hell. I have a staysail I can hank on to it.</p>

<p>Axel, I know this post is 3 years old... but what about using SS wire, and hand-splicing it (with soft eyes). Hand-splicing smaller wire eyes and inserting thimbles (hard eyes) is also not that hard. Then 'serve' the wire-splices to protect any sharp protruding wires/sharp edges.</p>

<p>In the process of finalizing the choices for standing rigging on a Tiki 38. Man, that heat-treated dyneema is expensive stuff! I can buy 500 feet of 1/4 inch, 316 stainless for less than the cost of 75 feet of 9mm dynex dux. While I appreciate the subtleties of the chemistry and manufacturing complexity, that is quite a difference in price. I have been practicing the required splices and really appreciate the ease of making them as well as the weight savings etc. </p>

<p>But galvanized or stainless stays bring different problems. Assuming self-build and the requirement to be able to make one's own replacements, there are hydraulic or manual tools available to make the swages, but it gets complicated to figure out. The inexpensive, multi-die hydraulic hand swagers use a hexagonal die, designed for round swage fittings, not the ovalized SS swage fittings needed for making regular loops in the wire. A hand press is available for the oval swage fittings but hydraulic seems ideal. </p>
<p>My 'money-no-object' preference would definitely be for dynex dux but using SS wire is 1/2 the price, including plenty of spare wire and the press tool. Anyone here have expertise in swage tools and fittings and has sorted this out? </p>

<p>Ahoy Ian,</p>
<p> Yes, the link didn't work and the search on YouTube came up with a lot of videos. Are you referring to the one by Zingaro (with the talented blonde crew)?</p>
<p> After trying your link my computer acted funny and I had to close the browser and do it all over again.</p>
<p>Thanks for the tip,</p>

<p>Today I have been working with Stayloks for non-dyneema areas, little bit of learning curve there. Hacksaw cutting -wire method in wooden template block simple fast easy, dead square and much better than grinder with heat/burrs. 24tpi hacksaw blade- new, chuck it after each wire. Interesting to note for silicone filling if chosen, that only non-acetoxy cure silicone should be used, ie neutral cure only otherwise corrosion may occur. I used a Sikaflex type.</p>
<p>Even though I have a "Cruncher" genuine Record wirecutter around 40" long! What a beast, handy for an emergency but a bit heavy. Burrs over the ends of the wire just a touch.</p>

<p>I wasn't against using lashings or soft rigging, but after failures I had to retrench. Obviously it is my method that didn't work out. It worked OK until conditions got bad, then they all failed. I'll see how this plastic thimble does. I would need to go on a 35 knot downwind run to duplicate the conditions. It was fun while it lasted.</p>
