Practice with the Uzukuri-Part 1
Seems like a cool way to use less than perfect wood and avoid all the perfect finish issues. Japan Woodworker stopped selling the brushes, so that left me no choice but to improvise. I tried all the wire brushes and coarse sandpaper I had in the shop and had mixed results. Pine is easy to abrade. Fir is much harder, even in the early wood. I got better results with a medium wire wheel at about 45 degrees to the grain, followed by a flap sander with [maybe] 150 grit paper.
It’s good enough for now.
