FTGF You got it! Thanks for watching Barry

Thanks for the tips! Barry

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.

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

Probably so, thanks for watching! Barry

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

Visack First of all thanks for watching! Secondly if you are talking about the original construction of a 20 year old boat you can rule out epoxy, I just wasn't used. Barry

@@barrylukebuilds7894 welcome

James I used the heaviest version that was available, can't remember the number. Barry

Calin I got my foam from Advanced Plastics In New Orleans. It's a 70 mile drive one way but it a freight bill than would have been a whooper! Thanks for watching. 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
