That’s what I was thinking

1708 or 1208 is 17oz biax or 12oz biax with a 8oz ChopStrandMat (1.5oz CSM in that standard of weighting). The CSM has styrene which dissolves with polyester resins (and I believe vinyl ester as well). It is not required for epoxy and will only make you use much more epoxy resin to wet it out without adding strength...

It was recommended to my be the guy at us composites and is what the guys doing the cedar conchfish used. I was also concerned about the amount of resin for wetting it out.
Chris said for the transom to use a layer of 3/4 core inside and out for the transom. I have had so many different opinions on the lay up Chris included it gets confusing.

Most people using composite cores are using polyester or vinylester resins, so their go to recommendation is the 1708. Feel free to call up Boat Builder Central (looks like that is the supplier you are going with) and ask. Jacquez from BBC/Bateau explained it to me about 3-4 years ago... Its more expensive than 17oz biax and you end up using more epoxy resin without adding any strength. IF you are using poly/vinyl ester resins, it is required because the styrene helps with lamination

It’s more less to get thickness not strength. I also don’t know why he would rather use cloth that biaxial since biaxial is so much stronger. Maybe I could add a layer of biaxial instead of cloth.???any ideas?

I am by no means a naval architect/engineer/designer, and would like to hear a lam schedule from someone that is. But if it were me, I would email Chris and ask. I would imagine something closer to: (inside out) core, 10oz cloth, 12oz biax, then 6oz as the outermost layer. And for less fairing/sanding, maybe use some peel ply. I would also run 6" 12oz biax tape at the chines/keel/transom areas.

I am definitely running a little extra glass on those parts. I have a roll of left of biaxial tape that I will be utilizing. I was able to get two layers of 50” on it tonight. I will sand it tomorrow and get another layer on it.

Rick, I believe this schedule you posted is for poly or vinyl ester resin, not the epoxy that Travis is using..

Yobata, I believe you are right. Travis, if you have any doubts on your layup schedule do email CM like Yobata suggested. He can adjust for epoxy, biax vs cloth, ect... at the end of the day he wants to see his designs be the best they can be and I’m sure he has an answer for you.

I washed the boat today with soap and water to get rid of any contaminants. Once it dries I will sand and finish the other layers of glass.

Damn, wish I would have found this thread sooner. I would have brought by some beer or something in exchange for letting me watch how you are doing some of this. Nice work!

Thanks, I like using it to get the glass to lay down in some spots. It helps a little.

I know!! It all laid down very well. And of course I decided to lay an extra piece of glass on the bottom to the bow. Guess what...it didn’t want to lay nicely like the others. But got it pretty good. Always my luck.
