Frames for the Merlin Yawl – an exercise in lamination

The onset of the U.S. tax season brought on the worst procrastinatorial tendencies here at Chine bLog Central, causing the main body of the editorial staff to shun the computer for weeks. This ordeal astern, however, I can report, at last, on another day building the Merlin Yawl at the Chesapeake Bay Maritime Museum’s Apprentice for a Day program.

I had left her with just a couple planks in place and returned to find her fully planked, with just some fine tuning of the sheer needed (1 block plane + 2 minutes of work). Inspecting the hull, I found a partial set of graceful, laminated frames fitted inside but not yet attached. Each of these frames for the midsections is a single, sweeping piece running sheer to sheer (see the first image below). They are really an impressive sight.

I briefly got up close and personal with one, in a scraper-and-hardened-epoxy kind of way, before heading to the table saw to start creating the next couple of frames.

Each frame is made up of roughly a dozen 1/8″ strips 1 1/2″ or so wide. We milled them from mahogany.

All these frames are laminated in place, so after slathering each set of strips with thickened epoxy, we wrapped them up, bent them into the boat at a pre-set location, clamped the heck out of them, and wedged everywhere we couldn’t clamp. The pictures give a sense of the process (I hope) and show the results: a couple frames laminating in place, maxing out the boat shop’s clamp supply.

A fun – and messy – day!

I saw a more recent picture that shows the interior painted, so the building of this great boat proceeds apace. I am REALLY looking forward to the launch in June. We’ll have full coverage here at Chine bLog!
