On completing the work of adding exterior base coat stucco, Sakaguchi-san measured the dimensions of door and window framing.
He then returned to his shop to fabricate the doors and windows. During this time, he also constructed framing components for the tatami floor and various cabinetry. He selected the lumber pieces which consisted of redwood, mahogany and rosewood, then measured and did the rough cutting of components. He squared them by putting them through the joiner and planer. He had to let them sit for some days in his shop to see if they twisted at all. The ones that did, he put through the joiner and planer again. For some components, he had to repeat this a third time before doing layout for the joinery.
After Sakaguchi-san finished the layout, he cut out the joinery and did the finish planing on the components, mainly by hand.
He then assembled the doors and windows.
When the doors and windows were all assembled, Sakaguchi-san transported them to the work site and installed them.
