No good. Already have all the material and someone on my boat who was supposed to be doing this job. He did he cores. Then he stopped working...
That's not how composite chain plates are made. They are made in situ
Yeah. I have to leave the marina for that type of open job. Nobody really wants to work so it's hard to find anyone. It's a labor shortage in...
I have some chainplates I need to put on the boat. They are 16 layers of 34oz triax and uni alternated. I can’t work with epoxy due to my...
This thread is about what you can substitute for plywood in this case.
The plywood is part of a buildup on the hull that receives the large plate that holds the strap in place. There are a few layers of 3/8 inch...
yes. Definitely. The epoxy grommet you are talking about is something I call “drill and fill.” I don’t make any penetration into any composite...
Are you sure you’re not a sailing person? Ha ha ha. you would be surprised at how accurate what you just wrote is. That’s the primary reason why...
Here is a heavily cropped part of the plans to protect the designer’s IP. See how it’s one of the old style internal chainplates with the...
hmmmmm. So you’re saying to take glass and just use that in place of the plywood? 1708 has Matt which is a bad choice as this is Epoxy...
I don’t know why I didn’t think of this. I do this all day long on deck. Why not through the hull? You did actually just make this metal chain...
The chainplate is about negative 2 weeks old. Looking to build them in the next couple weeks. I’d like it to last forever. That’s why I don’t...
I have a chain plate design that uses plywood in the mounting, with screws going through it. Yuck. What can I use as a plywood substitute?...
OK. Now I see. You are just thinking of a different kind of boat. This boat is already built. The main structural beams are in place. There is no...
I don’t think I have to worry about that at all. Why would I worry about that? You’re talking about torsion? That’s not what the beam does. All...
Of course. I have been in touch with everyone. Spar manufacturers are trying to charge $13,000 for this. Laughable. They required a picture of the...
Sure. A square beam could certainly work. No problem there. I’m not sure about the looks. What do you think? If I’m going square beam, I’m almost...
Very reasonable. And I did not consider this. I am curious however, where the rotational force would be coming from. If I go directly through the...
Note: I’ve found a 7” round tube with 1/4” wall thickness has a moment of 30, so I could just use that since they are readily available. I’d...
Moments are 25 x 11 for the required section. Yes, lots of masts. I went to Don’s Salvage. However, they are all too small. None had 9.5” x 5”...
