« Part 25: Attaching the Coaming Ring Part 26 of Building the "Swiss Army Knife" of Small Boats...Wood Duck Double series Part 27: Sanding the Boat »

Filing
There was quite a bit of filing to get all the layers even on the coaming ring. I used a Nicholson #49 rasp that was the perfect tool for the task. I’ve got grinder wheels from chair making that would do a quicker job, but doing it by hand was a more controlled and sure thing.

I sweated out my clothes on this job!

Routing
With the coaming layers evened up, it was time to route the top edge with a 3/8” round-over bit.

The routed edge came out nice and even. I then used an 80-grit disc on my random orbit sander to touch things up and round over the bottom edge. This is the area your legs rub against while paddling.

Fiberglassing

Fiberglass cloth cut on a bias of 45 degrees drapes over complex shapes quite well. I ordered extra cloth to be able to cut nice long strips for this and the extra coaming rings I’ll produce for the spray deck.

The cloth frays less when cut on the bias. That’s a bonus!

The inside angle is sharp, so I used two pieces at the bow.

Next
Apply second coat of epoxy to various parts and sand the kayak.
