Stus-List Re: C 35 MK I Keel Bolts
Interesting read. Fortunately Callisto's keel and bolts seem to be in great shape. One thing not covered in the article was lightning damage. A friend's Hylas was just discovered to have keel damage caused by a lightning strike, and had to have the keel dropped and re-bedded, and presumably some bolts re-cast into it. Fortunately insurance covered it, even though the strike occurred several years ago on the east coast. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C 35 https://www.facebook.com/SVCallisto On Tue, Sep 27, 2022 at 6:31 AM Dave S via CnC-List wrote: > Interesting indeed - especially the part about freeze/thaw keel casting > failures.he attributes these to bolt deterioration, but I expect that > leaking bedding, imperfect casting, or lose bolts may also contribute. > > Here’s what casting failure looks like: > > https://cncwindstar.blogspot.com/2016/09/mid-1980s-c-keel-issues.html?m=1 > > Dave Syer 33-2 > > > > >

Stus-List Re: C 35 MK I Keel Bolts
Pretty much as Dennis says, the fiberglass probably does compress a little. The fact is, that they do get loose as we all know. However that happens, they need to be kept quite snug. If you can imagine, having loose bolts and you tip your boat over 50° and imagine that lever flopping back and forth, compressing on a few inches of your glass stub.. it's one hell of a lever. In one of my recent posts on this, I mentioned something from the Tartan list on the subject. On there I saw a post from a friend of mine, who said you should never tighten your keel bolts. It was all I could do to not jump in there and say something, but amazingly, I refrained. But the fact is, if you tighten your keekbolts to the required torque, and they don't turn then everything is hunky-dory. What's wrong with that? If they do turn, then you know you had a problem. I don't understand how that could not be self-evident. But having said that, the keel should be so tight that it is a completely solid part of the boat, with absolutely no movement. The first time you see a check mark on your new boats keel, you know too late it probably should have been tightened, (unless you had a hell of a grounding) Not tightening your bolts is like pouring a concrete driveway, and not putting saw cuts in it because you didn't see crack the next day. You know sooner or later you're going to get cracks. So you'd better prepare for them..

I think if you had water ingress and sloved the issue by tightening the nuts on your keel bolts then getting good effect from the bedding compound used was the problem.

Stus-List Re: C 35 MK I Keel Bolts
When I first torqued the forward-most keel bolt, the 3/4" one, I heard some crunching sounds and found out there's wood under the top fiberglass layer below the keel bolt, inside the deep V of the lower hull. Pretty sure it's the same under the others farther aft. It was a tedious repair, done in conjunction with the mast step replacement.

Stus-List Re: C 35 MK I Keel Bolts
The fiberglass can compress of course. If you search for photos of keels being repaired, you will find photos of lead keels with the bolts being _rebedded_. MARSKEEL website is especially cool. Some of their staff worked for C They not only make new and repair old lead keels (both oem and custom) , they also make custom bulbs to reduce draft. I had some hope of doing that last year but unfortunately not an option for the stupid shark fin keel design.
Stus-List Re: C 35 MK I Keel Bolts
No! If the lead is soft, the keel will be getting longer as it sags. The shark fin shape will gradually become longer until it resembles the dorsal of a male orca. LOL :) I suspect the fiberglass may have compressed slightly. -- Dennis C.

Stus-List Re: C 35 MK I Keel Bolts
Second that. When I rebuilt my keel sump, I had removed the keel bolts, and I figured I should Re bed the keel at the same time. The boat was on the hard and not easily accessible by a travel lift, so I raised the hull as much as I could with the six cradle pads and cleaned out the keel/hull joint with a hacksaw blade. Imperfect but it worked. I used 4200 (iirc) to squeeze into the gap, and worked it in with a coffee stir stick. I then lowered the hull and partially tightened the bolts, then tooled the joint with an acetone dampened rag to remove the squeeze out. After it cured I torqued the bolts. I then had the impulse to skim the joint with an angle grinder, about 3” back on either side and I covered it with fine glass cloth and epoxy which I faired once cured. I figured I could easily skim it off if it failed (which I expected) or if I needed to do maintenance in future. 8 years later it’s still going strong, no issues evident, and the joint is undetectable. https://cncwindstar.blogspot.com/2016/08/repair-of-keelhull-joint-closing.html?m=1 Dave 33-2 windstar Sent from my iPhone > On Sep 13, 2022, at 6:59 PM, John Read via CnC-List > wrote: > > Remember 5200 is a permanent adhesive - not a sealant > > > > John Read > Legacy III > 1982 C 34 > Noank, CT > -Original Message- > From: james drew via CnC-List [mailto:cnc-list@cnc-list.com] > Sent: Tuesday, September 13, 2022 5:12 PM > To: Stus-List > Cc: james drew > Subject: Stus-List Re: C 35 MK I Keel Bolts > > Hello Dwight, > Did you use any bedding compound in the smile before you glassed? > I was planning on doing some tightening this winter and was contemplating > squeezing 3M 5200 into the smile before tightening and then glassing the > exterior of the smile. > Cheers, > jpdsailor=

Stus-List Re: C 35 MK I Keel Bolts
I did not use any bedding compound. Just used my angle grinder with 4 inch disc to grind out between the lead keel and the keel sump. Created a gap about 1/2 inch wide started from forward and aft about 2 feet or so. Cleaned up the 2 freshly ground surfaces and washed each well with acetone. Then painted unthickened West system epoxy on each surface to cure overnight. Then filled the gap with silica fibrr thickened west system epoxy putty. Then ground off rough edges and started laying strips of West system epoxy soaked glass matt to cover both sides. Three layers I think increasing from 1 to 3 inches wide. After curing faired with polyester car body filler. Nice job that lasted well for several years before I sold the boat.

Stus-List Re: C 35 MK I Keel Bolts
Nope. I can recall torquing on my 39, I have a 3/4" torque wrench with a 4 foot extension - I would have to put my left foot on the top of the socket extension, and my other foot on the bulkhead while pulling on the 4 foot extension, and that was hard. I eventually put Tef-Gel on the threads which allows you to use a little less torque. Stainless LOVES to gall on itself, and once a nut starts to lock up, you are screwed! No Pun intended. This comment below is from the Tartan site. Bill Coleman Keelbolt Torque 6/21/02 Good morning [all]. It appears the [folks here] have been busy coming up with questions regarding our keel installations which have been surfacing ever since I've been monitoring the list. I hope the following will answer some of your questions: Tartan uses a "Live" joint to mate the keel to the hull. A live joint is a joint that is able to flex during thermal expansion and contraction as well as accommodate movement in the structure while normally loaded as well as those occasional abnormal loads (grounding). This installation has been in use since the early 1960's with great success. One of the great advantages of this installation is that tightening the keel bolts will not promote water intrusion. We use a two-part THIOKOL adhesive sealant between the keel to hull joint which creates a permanent gasket. As you know, gaskets are used elsewhere on your boat such as on the engine water pump. Tightening the bolts on gasketed seals does not promote leaks as long as the bolts are evenly torqued. Keel bolts should be torqued to the following specifications: 1" bolts should be maintained at 350 ft/lbs 3/4" bolts at 250 ft/lbs and 1/2" bolts at 180 ft lbs. Tartan no longer covers up the keel to hull joint with glass tape for cosmetic purposes. For the last several years we have been leaving the seam exposed and faired with a THIOKOL bead to eliminate the maintenance issues with glass tape. Some other manufacturers install their keels with an epoxy joint. We don't find this to be reliable since the lead will expand and contract at a different rate than the fiberglass. If the bolts become loose the joint will fail and there is no chance of tightening up the bolts to eliminate a leak. A sudden impact can also jar the joint enough to break the bond. There you have it. I hope I answered all the keel joint questions.

From: dwight veinot via CnC-List Sent: Tuesday, September 13, 2022 11:16 AM To: Stus-List Cc: dwight veinot Subject: Stus-List Re: C 35 MK I Keel Bolts Yea when I torqued the keel bolts on my 35mkII I used a 4 ft extension on the drive knowing I could pull about 100 pounds so i figured about 350-400 lbft of torque. Trickiest part was finding space to get one click on the 3/4 inch drive ratchet. I used an extension from the socket down in the bilge to the ratchet about 2 feet long to get above the settees and that worked to get 1 click with the 4 ft extension on the drive. A wobbly setup but I got the job done complete with new bedding and 3/8 inch stainless steel backing plates below the nuts. Then I did the famous C smile repair from the outside and solved that ugly issue.
