Beach oil

Spent a day applying penetrating oil to the white oak in the screen porch.  This is what the raw wood looked like...

... and after oiling it looked darker, browner and more heavily grained.

The screen porch rafters are now topped with purlins.  Temporary plywood and tarps protect the progress from the weather.  Soon the plywood will be replaced with oak boards like the ones used inside and then roof shingles can be applied.  The next step is to finish the floor decking and fill in the screen porch walls.

To act as a passenger door, the left third of the screen porch door opens independently from the other two sections.

Or all three zigzag open.

When the door is stacked to one side, the living room is opened up to the outdoors via the screen porch.  It slides like a machine.  It was installed by a technician from the Kolbe factory in Wisconsin.
