Chain Locker Bulkhead (Page 2)

This page was last updated on 3 March 2002
 

Once the glued up chain locker door had cured overnight, I removed the clamps and prepared for a variety of milling operations.  The first thing to do was to sand off the epoxy that had squeezed out on the back side.  Next, I  milled a 3/8" x 3'8" rabbet on the back side all the way around.  This lets the door overlap the cutout in the bulkhead for a clean installation.  I used a stacked dado head in my table saw for this cut.  When that was complete, I replaced the dado with the regular table saw blade and, in two passes around the perimeter, milled an 11/64" wide by  3/16" deep groove all the way around for the reed spline that is used to hold the caning in place in the center.

When the finish was complete, I proceeded with the caning.  The process is described step-by-step below.
 

First, I cut a piece of pre-woven cane to overlap the opening by a couple inches on all sides.  Then, I submerged it in a bucket of warm water to soak for a while.  (15-30 minutes).  The reason for doing this is that the caning will expand when wet, and when it's tightly splined in place on the door, it will shrink as it dries, leaving a drum-tight surface.

To help hold the corners of the splines in place (they tend to want to pop out), I clamped each corner with a spring clamp to hold things in place.  I let the glue dry for several hours at least before continuing.

After I let the glue dry, I trimmed the excess caning and spline with a sharp utility knife, cutting just outside the spline all around.  This completed the construction of the door.  Next, I installed two brass 3/8" overlay cabinet hinges on one side, and a brass knob on the other side to match the rest of the doors in the boat.  Then, I installed the door on the new bulkhead (still in the shop), along with a brass door catch.

Bringing the whole assembly up to the boat, I installed the previously test-fit bulkhead permanently in place.  It serves no structural purpose, so I attached it to the existing partial bulkhead and new overhead plywood beam with a series of screws from the back (chain locker) side.
