Rear Cabin Wall and Seat Back Frames.

 Rear Cabin Wall install.

I spent a couple of hours tracing the rear cabin wall and seat back frames onto 9mm ply. After a bit of jig saw work the rear cabin wall was stitched to the cockpit seat. I used clamps on the hull sides to temporarily hold the cabin wall in place.  

The correct angle was secured by screws through the hull sides and a temporary cleat screwed on top of BH 2 and the rear cabin wall.

Seat Back Frame Install.

To locate the position of floor 6 I used a laser level from the hull bottom and transferred it to the top of the hull sides.

The seat back frames were stitched in place above floor 6, BH 7 and BH 8.

To align the frames athwartships a length of timber was clamped at the base of the frames. 

A carpenter's square ensured the frame was perpendicular to the cockpit prior to stitching the frames to the hull sides.
