From 36 Steps to 40 Steps

From 36 Steps to 40 Steps
The typhoon has moved away from our area, and it has been sunny since this morning. However, the temperature returned to a summer-like level and rose to around 30°C. It often becomes very sunny like this after the rain from a typhoon. This was another large typhoon that caused flooding and other damage in many places. I think many people are still busy cleaning up. Today is still a holiday, and Silver Week in Japan continues until tomorrow. I had some errands to take care of this morning, so I went out and stopped by my workshop on the way.

Along with the Square puzzle boxes, including several limited editions, a small number of 5-sun 36-step puzzle boxes will also be completed. This box recently sold out, so it seems to remain a popular model. This time, I made only the traditional Yosegi version. I also wanted to make several designs for wholesale, but unfortunately I was not able to do so. The next time I make this box, I would like to include a special design that combines traditional Yosegi with Ichimatsu Yosegi. I have not made many large puzzle boxes for wholesale recently, so I hope to make one more type before the end of this year. It will be a 40-step puzzle box.

I mentioned this on my blog a little while ago. I had been thinking about using this mechanism to make a puzzle box with a higher step count. However, if I keep as much of the same mechanism as possible, I have come to the conclusion that 40 steps is the most realistic number. Of course, 36 steps and 40 steps are not very different. Still, I would like to make one and see how people respond before deciding what to do next. According to my current calculations, reversing the direction of the mechanism and adding a few extra parts should increase it to 40 steps. However, I still need to think a little more to make sure my calculations are correct!..haha
I could increase the number of steps further by adding more sliding keys and making the mechanism in two levels. However, this would make the mechanism very delicate, and I would be a little worried about shipping it overseas. Changes in climate can easily affect such a fine mechanism, so I do not think it is very practical for a box that will be sold. This is also why I have not made any 54-step puzzle boxes recently. Even if the owner takes great care to keep the box in good condition, it may not be able to withstand a large change in climate. For these reasons, I think a 40-step puzzle box may be the most realistic choice for now.

I hope to make this 40-step puzzle box before the end of the year, including some for wholesale. The idea behind this 40-step mechanism is the same as the 18-step puzzle box that I have made before. The original mechanism would open in 15 steps, but I added one more sequence on the opposite side. In the case of the 18-step box, this added three more movements and increased the total from 15 to 18 steps. In the same way, the sliding keys on both sides of the 40-step box will have a return movement called “Kaeshi.” On the current 36-step puzzle box, this Kaeshi movement is used only on the sliding key panel on one side. I think this method should work. However, the 5-sun 10-step puzzle box with a drawer also looks likely to sell out soon... If possible, I would like to make both types...
