[yobata]

I tried searching for your build thread on Bateau but could not find it. Could you provide a link? I am very interested in watching your progress. Will you be updating both Bateau and this site or is one going to be more detailed than the other?

Thanks!

@Travis Smith Are your stations just MDF? Why didn't you make some of the stations that will become the bulkheads and the transom from the core material? It might save you some time later?

Also, did you have the plans printed to scale to precisely shape the stations or just from measurements?

Looks awesome just sitting on that strongback!!

 

[yobata]

Where are you located? Maybe a closer supplier (even if the price per sheet was more expensive) would be a better option?

 

[yobata]

Atlantic Coast Marine in Jax has the ability to order core material, but I have no idea about their pricing

 

[yobata]

Were measurements for the stem included in the plans? Looking good!!

Is the plan to cut the core into strips (similar to a cedar strip build)?

Also sorry for so many questions, but if you can't tell, I'm really enjoying your build thread!

 

[yobata]

Is core going on the chine notch part? How tall is the transom, 15" or 20"? What fastener are you using to fix the foam strips to the frames?

I'll share this link with you for a polymer nail/staple producer that may be useful since you can easily sand it off and it doesn't require removing and filling the holes with epoxy: http://raptornails.com

View attachment 28854 View attachment 28855 Moving right along. However with NE FL weather I don’t see my self glassing anytime this week.

It took me 4 sheets of 3/4” Divinycell and about a half of sheet of 1/2” for the chines. I still have some 3/4 and 1/2 left over.

Wow Travis! That looks great! I have a couple of questions for you:
1. I remember there being strikes on that skiff, are you adding those and if so before or after the outside skin is laid up?
2. It looks like you are using Gorila Glue to join the strips of foam core, can you talk about the thinking here? Are you at all worried about the bond? Would it have been a better idea to use an epoxy? Or does it even matter because you will use a (poly if I remember from earlier) resin later on that will bond with the skins on the laminate?

Thanks! And again, looks great so far!!

What's the layup schedule for the outside skin?

Thank you.

What does it call for transom thickness? 1 1/2 of Divinycell?

Why 1708? That isn’t compatible with epoxy, correct?

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...

 

[yobata]

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

 

[yobata]

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.

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

 

[yobata]

@Travis Smith looking so good!!

1. When did you remove the screws holding the foam to the frames? Before the skim coat of thickened epoxy? And if so, when you removed the screws how did the foam stay in place, just the gorilla glue??

2. How did you radius your corners at the chines, etc in preparation to the cloth? Did you use a router or just sanded by hand?

 

[yobata]

I have a small 5x9 layup table that I use to layup the full sheets...

Those dimensions can only mean one thing!!

 

[yobata]

@Hardluk81 has a good point, and I believe you said no false floor/sole on this build, so it makes perfect sense to stop you from the chine cutout

 

[yobata]

What are thise?

They are clay shaping tools - $8 on Amazon - https://www.amazon.com/AIBER-Sculpting-Modeling-Double-ended-Decoration/dp/B01F554LOU

 

[yobata]

The biggest I found was a 12 mm y’all think that’s ok?

The link I sent earlier has them up to 17

 

[yobata]

Travis, how did the hull laminate schedule differ from your deck? Couldn’t find it in the thread(if it was discussed what page)

Thanks

Deck is flipped over... it turned out pretty good.. I do have some wood that stuck. So I’m sure it will be a pain to get off...

So... Have you hopped on top of it yet?

 

[yobata]

Let's get back to the real questions: 1. Why are you not posting more photos, you skiff tease?! 2. I know you think that you're giving us enough updates, but I need more. Redundancy is never a fault, shower me with pics!! I want to see her from all angles ...

meyeaw!
