In this episode of the Art of Boat building, Boat Builder Bob Emser, show how to easily laminate a stem for the dingy “Victoria” The stem is the first structural member for the sailing dinghy that will be the tender for Steve Denette’s boat Arabella. In this woodworking video, Bob show a technique for getting uniform strips of the for bending wood. Using a wood bending jig thin strips of White Oak are bonded with Titebond III glue.

Thank goodness for plastic in this effort. While there are many areas that plastic use can be reduced, it should not be eliminated. And there are research efforts going on that take very specialized microorganisms that can digest plastics and return them to their original chemical (or other useful) components.

Glad you're back up to snuff Bob. One question though: Why did you go with titebond instead of epoxy? I know type 3 has the longest open time but it's still only around 10-12 minutes. Maybe a bit more in a cooler environment. I would have been seriously stressed!

@@holmesanderson5067 Yeah, Bob has his own way of doing things but you can't argue with the results. The table saw technique was pretty scary though. I was surprised that he didn't use and mdf form too but the parts seem to the correct shape. As for Tightbond 3 you are spot on but I'm guessing he's using it because it's a dingy and won't be in the water all the time although if Steve is at anchor some place my guess is it will be in the water for days or weeks at a time. I'm wondering if he's going to glass it. If not I, like you, have concerns. I'd love for him to weigh in on this.

More laminations leads to less springback. The first lamination didn’t appear to springback at all. There are some rough formulas for calculating springback.

Far be it from me to suggest how to make your process better but I wondered if you could put the king “tails” of your clamors on the outside of the jig and the heads in the inner curve to keep it from getting so crowded? I feel like I’ll do it one day and mid way through the glue up realize there was a method to your madness and I’ll be scrambling to redo them. Is there a reason I’m not seeing?! Beautiful work and fantastic explanation sir.

@frommyashesrisenrebornredemed Жыл бұрын

I had the same question but In an other (older video) he stated that some people use epoxy everywere. He has done some tests if i remember correctly, and he said that for the application that he will be using it, the woodglue will be suffisiant. In the end the whole boat will be coated with epoxy so that wont be much of a trouble.

@@TheArtofBoatBuilding Aha. I've experienced that. Nicely planed white oak can have a surface as smooth as plastic. When I've epoxied it, I would rough up the surface to give the epoxy something to grip on to. But for something that will take stress, it makes sense to use a different adhesive.

At 14:29 what is the glue lam life with titebond vs. epoxy?

@TheArtofBoatBuilding 4 ай бұрын

Titebond III is not effected by UV light. Unprotected epoxy degrades in UV light. I epoxy is protected they will perform the same. Traditional epoxy should not be used with White Oak. One reason is its lack of dimensional stability. All wood reacts to changes in moisture content. It shrinks as it loses moisture and it swells as it gains moisture. Typically, the movement is much greater across the grain of the wood than it is parallel to the grain. This movement can result in warping, splitting, checking and other problems. Oak, especially white oak, is one of the more dimensionally unstable species of wood. It twists and bends as it tries to adjust to changes in its moisture level. For example, when its moisture content changes from 7% to 12%, a piece of white oak will swell about 50% more than a piece of Honduras mahogany under similar conditions. With this much movement, the stress on a glue line becomes enormous and can pull the joint apart. One could use a flexible epoxy adhesive, such as TotalBoat FlexEpox, or WEST SYSTEM G/flex to bond white oak. Titebond III plays well with white oak.
