Stress Free Epoxy Glue-up on the Poulsbo Boat - Episode 10

Hey folks, welcome to Nomad Boat Building. We're picking up where we left off on the Poulsbo Boat Project.

In the last episode, I fitted and steam bent the longitudinal members that will become the inwales and thwart risers. This time, it's time to glue everything up.

I'm using epoxy to laminate the inwales and thwart risers into strong, rigid structures that will become an important part of the boat. I'll show you how I prepare the surfaces, use two-part bonding, choose between different types of clamps, and use polymer nails to hold the laminations in position while the epoxy cures.

I'm using WEST SYSTEM 105 Resin with 205 Fast Hardener for this glue-up. The two-part bonding technique involves wetting out the wood with unthickened epoxy first, followed by thickened epoxy to create the structural joint.

The Poulsbo Boat is a modern cedar-strip version of a 1950s-era sport fishing boat originally built by Roland Young in the Poulsbo, Washington area. The original was built using traditional carvel plank construction; this version is being built with cedar strip construction and fibreglassed inside and out.

There is one more tricky piece to add before this stage is finished, and I'll tackle that in the next episode.
