Urgent Ichimatsu yosegi work

Urgent Ichimatsu yosegi work
Today is a holiday in Japan. Yesterday was Labor Thanksgiving Day, and since it fell on a Sunday, today became a substitute holiday. The long autumn rains are over, and we now have clear, sunny weather. It has become quite cold, and I can really feel that winter is coming. The autumn leaves are at their peak in Japan right now, so many mountain sightseeing spots are crowded. The mountains are a bit cold, but they are definitely worth seeing.

I went to my workshop this afternoon and did a little more work. First, I continued making the ichimatsu yosegi for the 6-sun box, which I started yesterday. I cut the striped block I made yesterday into pieces that are 6.5 mm wide. Since the striped block is about 350 mm long, I was able to get 43 pieces from it. I made two blocks, so I now have a total of 86 pieces. Next, I glued them together in groups of 14, making sure the colors alternated. This gives me six sets, with a few extra pieces left over. Tomorrow I will connect those six sets side by side. If my calculations are correct, the connected piece will be about 300 mm long and about 90 mm wide. This size becomes one long side and one short side of the yosegi for the 6-sun box. Since the 6-sun box is large, I need two of these yosegi sheets to make the side panels for one box. The box is so big that making all the side-panel yosegi from a single sheet is difficult, so I divide it into two sheets.
This time I’m using slightly harder walnut wood. This wood is a bit difficult to slice, but since it’s for a 6-sun box, I wanted to make it a little special 🤣 Another reason is that I don’t make as many 6-sun boxes compared to 4-sun boxes, so I want to put a bit more care into it (It doesn’t mean that the 4-sun boxes are sloppy..haha 😅)

After that, I attached the Aruki moving panels for the 36-steps box and prepared the next step, which is the top and bottom panels. The top and bottom panels already have the yosegi sheets attached, so the next step is to cut them to fit the box. But before that, I sand them well while they are still in the large board form. I will sand them lightly again right before painting when the box is finished, but at this stage I sand them carefully.The yosegi sheets attached to the board have a rough and uneven surface. By sanding them, I make the surface as flat as possible. By doing this, I can make the finish of the coating much smoother and cleaner.These panels (especially the side panels) also seem to have dried well because of the dry outside air over the past few days.
