Types
For gyo daisu, the sizing isn’t a ro/furo thing. Rikyu take-daisu is smaller than Joo-daisu.
Orientation
Just like Tana orientation of wood grain, the rings on the tree should grow from katte for ji-ita. Opposite for the ten-ita.
The most common take-daisu legs are 3322. Lower right and upper left legs have 3 fushi, other two have 2 fushi.
However! I’ve heard something more specific from iwama sensei. If you don’t have the standard 3322 daisu legs:
- Starting from the lower R corner and working clockwise, the bottom-most fushi should go from lowest to tallest.
