RE: [Cal_Boats]Monel, UHDPE, Salsa, rigging (Charlie)

Charlie, I guess that's my point, as far as I know there's no such thing as a dyneema bolt, although dyneema has a higher tensile strength than steel, or, at least, stainless steel cable of the same diameter. --- On Sun, 4/19/09, Husar, Charlie [USA] <hu… [at] bah.com> wrote: From: Husar, Charlie [USA] <hu… [at] bah.com> Subject: RE: [Cal_Boats]Monel, UHDPE, Salsa, rigging, was: cal20 bulkheads To: Ca… [at] yahoogroups.com Date: Sunday, April 19, 2009, 4:48 AM  Hi, Jerry. Here is what I got from McMaster-Carr web site. Don't know much about these things. About Plastic Cap Screw Material Types Plastic Type Features Kynar Possesses excellent corrosion and chemical resistance. Also known as PVDF (polyvinylidene fluoride), it's a tough and durable material. Nylon 6/6 This nonconductive material resists chemicals and solvents, except mineral acids. PTFE Has high dielectric properties, so it's perfect for electrical applications. Resists moisture and chemicals, and has excellent mechanical properties. PVC Provides excellent corrosion resistance against weak acids, alkalies, and alcohols.

OK, What about Ultra High Density Polyethylene? My new centerboard will be suspended by a cable of such stuff, no more worries about corroding copper swedges!!!! That was the down fall of my old one (no pun intended). Does anyone make UHDPE fastners? If not, why not? And why not UHDPE instead of carbon fiber? I bet it wouldn't fail catastrophicly, maybe just creep to death if it is woven. And what about the new "ultra-high strength concrete? Sounds like good centerboard material. Gotta check this out. Jerry PS BTW my main halyard is SK75 Dyneema, 1/8" fits nicely into the groove of my halyard sheave. (it might be the old SK60, all I know is it was called Amsteel, and has a silver color to it). The latest stuff is SK78, heated and prestreached, it has less streach and creep than SK 60 and 70. BTW, anyone use New England rope Salsa single braid for genoa sheets? What about those new synthetic thimble style shackles? There are new ones out that look like miniature hangmen's knots with a little tiny line to disengage them. --- On Sat, 4/18/09, Lord Nougat <lord_nougat@ yahoo.com> wrote: From: Lord Nougat <lord_nougat@ yahoo.com> Subject: Re: [Cal_Boats] cal20 bulkheads To: Cal_Boats@yahoogrou ps.com Date: Saturday, April 18, 2009, 7:16 PM Seriously?

My comment would be: Congratulations! Here's a summary of an offline conversation I had with a lad who works at Schooner Creek repairing CAL-20's. There is quite a large fleet up there. One thing that is not in the discussion is the cost of keel bolts. Most of the stuff I need to fix up my boat will be purchased from Steve Seals so I don't mind saying that if you drop the quality of stainless steel on the bolts to one grade lower you save over a 100 bucks and available anywhere. Personally, I don't think it makes a difference if the bolts are properly sealed and routinely checked. The bolts specs are here: http://www.go2marin e.com/search. do?q=fasco+ screw+30995& x=21&y=13 Fasten All in Canada has the same bolts in a lower quality of SS for 17CDN a piece which means I also don't have to deal with the 20 percent exchange rate. Best of luck, they are very nice boats. BTW...if you do buy a CAL-20 I think you will be either the 4th or 5th Crhis on the list with a CAL-20, its getting rather weird, as Chris's seem to like CAL-20's. Perhaps we should run a pole or something on the yahoo page to see what the names of other owners are on this list with a CAL-20 Enjoy the boat.......she' s sweet. -- /ch Information from ESET NOD32 Antivirus, version of virus signature database 4018 (20090418) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset. com
