Re: Stus-List Subject: Re: Keel repair

In my case, was not suggesting it is superior, I just prefer to purchase the raw materials. This way, I can use unfilled as a first coat, make a putty for the fill, and laminate at the end. Same epoxy, sometimes even the same batch for multiple applications/jobs. YMMV. Dave On Tue, Nov 24, 201

Ahmet; As I said before, I replaced the original steel backing plates (if I recall, they were more like steel fender washers) on my 25 when she was a bit over 20 years old. I had some square backing plates made out of 3/16” or ¼” stainless. About 3 or 4 inches square and with the proper size

Re: Stus-List Update: Re: Keel attachment issues on a C&C 25

Repair sounds excessive to me. I already suggested thickened epoxy/Six10 glopped in as a leveling agent with the 1/2" G10 on top. G10 is supposed to be pretty hard to cut so thicker is not necessarily better. If you do not plan to allow for removal of the G10 then I would fill and fillet the ed

Re: Stus-List Low viscosity Epoxy was Re: Subject: Re: Keel repair

I recommend a small amount of thickened epoxy under a piece of G10. If you use a low viscosity (read un-filled) epoxy it may not be reliable under the keel bolt clamping force. If I was performing the same repair on Calypso I would clean / roughen the area, butter in some thickened epoxy, plac

Re: Stus-List Low viscosity Epoxy was Re: Subject: Re: Keel repair

The best way to get a very level and flat surface is to use thin epoxy... But then it may squish or flow out and allow for voids. Besides that, you MAY want to create a damn around the keel bolts. I don't think crumbling is going to be a problem. The 12000 psi coming from the keel bolts is "poun

Re: Stus-List Low viscosity Epoxy was Re: Subject: Re: Keel repair

Well, there aren't any absolute answers. Some solutions are just better than others. I like epoxy for injecting, flowing and uneven surfaces. It is much less viscous than most putties. It fills voids if you don't mix it too thick. Like many of us listers, the best technique is to coat the adher

Re: Stus-List Update: Re: Keel attachment issues on a C&C 25

Hi Ahmet, Get rid of the galvanized washers now, they will corrode. The rest of your repair sounds fine. If you look at the pictures of my bilge you will see that under the nuts are a stack-up of stainless washers. The number of washers will depend on if you have a deep socket or not. You

Re: Stus-List Update: Re: Keel attachment issues on a C&C 25

Ahmet If there is oil or grease on the threads of the bolt you should reduce the torque by aprox 10%. Torque numbers are given assuming threads are dry. Using lube would cause an over tightened condition.

Re: Stus-List Epoxy fillers and other stuff...

If I may add to that exhaustive list of advice, ascetic acid (vinegar) can be used for cleaning epoxy, before it hardens. It gets into reaction with epoxy resin monomers and neutralises them in the process. So if you are doing any epoxy work it helps to have a bottle with vinegar and a rag han

Unfortunately, you will not have enough time to do a real day rental. Ships arrive in the morning, takes some time to get off and go anywhere from the terminal. On the other end, you want to be back at the terminal with a bit of margin, they can leave you behind. In most ports you can find a
