Bulkhead #3

Bulkhead #3 is one of the two bulkheads that the cross beam gets connected to, thus deserving special attention. At this point I have dry fitted bulkheads 1, 2 and 3. Before glueing them in place I decide  to add as many of the extra pieces that make the beam box before bonding the bulkhead.

For many of these joints I am bonding with thickened epoxy and silicon bronze screws.

I also added the first brace for the beam box at this time.

Finally after two coats of epoxy to seal everything up the bulkhead is ready to install.

Clean with water and a scrubbing pad to prep the surfaces one last time, You can tell above how much dust still needed to be removed. Then I clear coated the mating surfaces and added a nice bead of thickened epoxy. Here we don’t care how much oozes out since it will be used to supply the extra epoxy for the fillets. Cargo straps tighten things up.
