I trying to find out what the foam cored material is called that some people had sucess with while replacing the wood stringers

sosmarine

Call Cape Horn (Fabro) they can tell you. I was just up there last and got the tour. Don't remember what it is called though.

X-Shark

You have several options.



You can build a mold and make the stringers, then tab them into the hull and fill them with 4lb density pourable foam.















Part being vacuum bagged.













You could use Coosa Board as a core. There are also some other high density core materials.

the prima preforms are what I was looking for. But X,you have a really good Idea. anyone know what the preforms run?

I have actually seen them a West Marine at one time. They are expensive, but what isn't on a boat.



I checked their website and nothing showed up. They may have dropped the line as it would not be a large mover, yet does take up a fair amount of shelf space.







I even found a listing from 2002 about West Marine carrying that product.

I think I'm gonna go with your idea ,X-shark. My question is can it be done with a vacum setup?

chris

X-Shark

Yes. that part is being vacuum bagged.



Now i think maybe you mis typed? is your question Can it be hand laid? The answer is Yes also, but you get such a nice part by vacuum bagging it and anytime I can vacuum bag something I do. You get zero voids and a lighter weight part.



There are a few other things to this in making a part, especially if your making short sections and butting them together.



It's to much to write here, but I will explain it if you come talk to me and I will show you some samples too.

your right it was a typo. I'm still stuck up here in VA till the doc releases me . I'm doing some reading up on vacumbagging now .I think I'm gonna get a set up. It's not a terrible amount of money for a good setup considering what can be done with it .

X-Shark

This is a pix that I left out from the above pix's.



This is the waste factor when doing vacuum bagging.



What you see in that pile is the bag [which can be just a piece of 2mil visqueen / plastic sheeting.]



You also see a sheet of bleeder material. it is a cotton like fabric that allows air to go thru and absorbs the excess resign.

4oz bleeder cloth is $4.75yd. That is 60in X 36in



Next is the Peelply. This is what will allow everything to release from the laminate. Never try to pull the peelply until the laminate is fully cured. It is $6.50yd to $10.50yd depending on what resign you use. Again this is 60in X 36in



Once used, this is ALL thrown in the trash.

Here are all the parts fitted in my boat.
