Here I've mounted the base for frame 4. When I assemble the boat I will glue and screw the sides for frame 4 in place.

The arch for bulkhead 3 is now in place. All that remains is some finishing and fairing and this bulkhead is ready to go. Once the cabin is nearly complete, I will saw out the part of the arch that covers the companionway. For now it serves to help keep the bulkhead squared up.

The arch for bulkhead #1 is setting up. This is a departure from the plans, which call for sawn planks to be laid against the plywood where this arch is.
