Wooden Boat Building - White oak vs Red oak with Louis Sauzedde

Great Scot

Gracias!

Don't spill your drinks in a red oak boat

The faster growth rate of the red oak in this example helped exaggerate the difference between the vessel structures of the two woods. But it is still a scientifically important experiment in that it demonstrates the quality of the White Oak closed vessel compared to Red Oak.

I just look for the presence of tyloses. White oak has them.

Could a person just soak their wood construction pieces in penetrating epoxy or even just boiled linseed oil in order to seal those capillaries, prior to construction?

Nice presentation but I need to comment on how you use the word porosity. Porosity is a static property of a material. It can be closed cell or open cell. If it’s closed cell the water or alcohol will not move (or hardly at all). The word you need to use instead of porosity is permeability. That’s the dynamic property of the material. Two samples of wood can have the same porosity but very, very different permeability depending on whether the cells are connected or not. The red oak you showed is porous AND permeable. The white oak can have exactly the same pore volume but be mostly not permeable.
It sounds trifling but words have meaning and porosity is commonly misused the way you used it in your nice demonstration. Try distinguishing between the two words and you’ll find it’s better descriptive of what’s going on. In other words don’t say porous when you mean permeable.
Thanks for reading my comment.

Woodglut is nice for that.

Now there's a man that knows his stuff 👍

Thank You,Sir.

So red oak would be good for desalination sea water in a survival shipwreck situation... good to know.

Great demonstration. Years ago, I showed a supplier that I could blow bubbles through a piece of supposed "white" oak and that charactistic was a problem. He was relying on color, which is not reliable. Also, I've been told that there are numerous oak crosses or hybrids that can have characteristics of either parent species. Ex/chestnut oak.

What is the best wood to use?

Now I know why a woodworker friend cussed me out for making a replacement thwart of red oak for my canoe.

Thanks for the very detailed explanation

Fabulous information.

good to know ... no question ... thank you

The capillarital porosity of the medullary ionization is remarkable!

I learn more from you than anyone else I've ever listened to.. I love your videos

Guy comes home one night and wife asks, "what's with the breath?" Husband says, "just been working some wood with my mouth."

LOU, wouldn’t the capillary action on red oak make it better for absorbing various epoxies and glues and thus make for a better wood/fiberglass boat (so long as wood is completely covered) even though a terrible wood only boat?

Thanks for sharing your knowledge!

Once staining a red oak post for a stair handrail in a house. Started staining at the top of the post, within seconds the stain was flowing out the bottom end.

Woodglut Blueprints has some very useful blueprints with all the details you need.

These videos are great throw in the physics and chemistry with the craftsmanship,...what else do you need

Very smart i cut wood 30yrs

Very very useful video. Thanks!

Love this man.

Ingenious. No one else was able to tell me how to figure out if my floor was red or white oak. Now I know. I cut a bit out and its white for sure.

I was researching wood for aircraft and came across forest product laboratory report 354 which stated that white oak heartwood was impervious to water. Making me concerned it may not glue well... this is a great report to take a look at. Thanks for this excellent demonstration!

So, red oak is white and white oak is red.
Got it.

Just found this. After 45 yrs of working with wood I was just reminded of how little I know. Binge watching time...thank you Lou for the schooling - just amazing.

Thanks great demonstration

Cool science.

Seventy-seven red oak trees downvoted this video.

Excellent presentation. Thanks! Now, I understand the importance of using white oak and not using red oak, and I know how to determine which is which regardless of how it’s labeled when sold. 👍🏻

I learn something every single time I watch one of Lou's videos. That was a very informative demonstration.

Quick question, why does red oak look whiter than white oak?

Fantastic presentation. I wonder where the DC current comes from?
Is this the current that dissociates the Sodium and Chlorine from the salt? Or is this current generated when the NaCl dissociates into its ion form?
We can see how the Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) can form but when mixed together they neutralise and form Salt (NaCl) and Water (H2O).
Is there a process occurring inside or on the surface of the oak wood? It’s either that or an external current is present that drives the chemical reaction in one direction.

you should teach in university

Great demo!

It would be interesting to soak red oak with wood hardener. If it could totally wick into the wood, you could end up with hybrid product that is impervious to water, and stronger than the original board.

Cool info

So the Red Oak is white-er than the White Oak, and vice versa. That... Doesn't really make sense.

I would love to know what it does in water, is it the same as what happens when in wudduh?

This was very educating. Thank you a lot!

and can you imagine that some not very kind human beings are making fruit press out of red and selling it for good money where lot of fruit pulp goes in to this channels and rots there and then... -.-

this redish peace here is white oak and this white peace of here is red oak. well thats not confusing at all

Thanks for the explanation sir. I built a captains chest out of white oak once but only because the chest I was copying was white oak.

Very good design of experiment !
