The new foam cores for the stringer replacements are now installed in the center console project boat. We are using Divinycell board for the cores.

if you use laminating resin (no wax) it will set up but the surface stays open so you can apply more layers of polyester resin the next day or the next week. once you are done you apply a finishing gelcoat or a finishing resin to cure the surface. You can also spray it down with pva to completely cure it.

I use thickened vinylester with a flexible spreader on the foam core mixed cold at 1% mekp then add wet biax on that . The core never holds the liquid resin and the cloth falls off to easy.

Vet man If you are saying that mat will not stick to Divinycell when using unthickened resin that's the first I have heard this. The foam does soak up a lot of resin so if the foam was not pre-wetted out maybe the mat was starved for resin? Seems to be working for me.

@@barrylukebuilds7894 foam core takes liquid resin best in a vacuum bag, when hand laying foam board the best lay up is to push thickened vinylester into the foam then lay up the pre wet 17-08 on top . No voids. No need for vacuuming and good on vertical surfaces.

Question for you, how would you make a 12' stringer out of a 4x8 sheet of divinycell foam?
@barrylukebuilds78943 жыл бұрын
ADD Foam cores for stringers and bulkheads are simply cut to size and butted together if additional length is needed. The strength of the stringer's structure results from a combination of things. Strength and thickness of the laminates on each side is a big part. The thickness of the foam plays a part as does the foam's ability to accept and bond to the wet resins during layup. The shear resistance of the foam itself plays a key role and joints in the foam do not have much of an effect on this. Also important is the fact that structural foams are resistant to absorbing water and rotting. Barry

@@barrylukebuilds7894 Hey Barry, I have a lead on a sheet of divinycell foam, 1.25" thick. Seems big enough, but what density would I need for my transom? less concerned about the stringer but just trying to make sure I buy the right stuff.

@@ADDvanced I don't have warm and fuzees about this. I know very little about Divinycell other than the sheets I purchased and used. Those sheets I don't think were ridged enough for a transom. I would be concerned about the engine bolts crushing the core. There are ways around this but it gets complicated. I would contact a sales rep and see what his opinion is . Thanks Barry

Looking good. I really enjoy your updates. What kind of engine do you plan on putting on the boat? I have a yam f250 on my Seahawk.

Chris How appropriate to own a boat named after yourself! No decisions on power yet unless someone offers me a one your old outboard with about a hundred hours at about half retail price. If that happens then that will be the brand I use. Glad you are enjoying, thanks Barry

I wish I would have seen the first video when you did it. I could get given you as much information as you would have needed. I have been doing this for over forty years in New Orleans. I have known Mike at Advance plastics sense he started working their his father owned the business before it was called Seaman Plastics. Originally owned by Bill Seaman who was the person who invented C'Flex which is what most of the Lafette Skiffs are built out of
