Update!
Worked on the bedroom sliding door cutout. This space is required to allow the door to clear the side of the body (height of the door maximized so in the open setting it just clears the curve of the exterior + insulation).
The cutout unfortunately was at an odd angle, but a metal blade made quick work of the aluminium.
Next step is to insulate and apply skin to the door and install the sliding hardware. I am working on a lock design since the rear bedroom/desk/bathroom space is for private use, and the front more for event volunteers when we are running events.
The frame is aluminium 1″ medium wall box tube TIG welded rectangle.
More to come soon!
