-- Original mail: -- Thanks Rick. I did read your email (to this thread), and one from Apr 10 2014. I think that's it unless I missed one. A wire conversion has only two tricky parts to it - the mast fittings, and the spreader tips. So I'm trying to figure out more details about those. There are a few things not clear to me about your wire rerig: - What changes were made with your mast fittings (navtangs), if any? It sounds like you got Navtec stemball fittings swaged onto the wire and reused the old navtangs. Do you have K150's or K200's, and do you know if the tie bar was inspected? - How does the spreader tip connection need to change for wire? The 38 Mk 2 rig might be a little different, but my upper main shroud is continuous at the upper spreader. Does wire necessitate any changes there? The lower spreader tip is also a little tricky (because it has three wire terminations in it). I do agree nitrionic 50 rod is a marvelous engineering feat, but there are appealing aspects to Dyform too (including that there are many more places that can swage wire). The interesting thing is navtec's site says Dyform, at the thickness giving comparable strength to -10 rod, has nearly the same low stretch as rod. Dyform at 10000 lbs is 0.00085 stretch while rod -10 is 0.00083. I'm going to ask a couple riggers about that. http://www.navtecriggingsolutions.com/rigging.html -Patrick 1984 C&C LF38 On Sat, Nov 19, 2016 at 5:20 PM, <cnc-list-requ...@cnc-list.com> wrote: > From: Rick Brass <rickbr...@earthlink.net> > To: <cnc-list@cnc-list.com> > Cc: > Date: Sat, 19 Nov 2016 20:19:58 -0500 > Subject: Re: Stus-List Pointers on re rigging an LF38 > > If you go back a few weeks on the list you will find a lengthy post from > me telling about my experience replacing all the #10 rod on my 38 mk2 with > Dyform wire. > > > > The wire has a little bit higher tensile strength than the rod.
