a gradient of blue to map 25 - 47 power to circles, and red to score the annotations.
We found out the circle is barely detachable at power = 35, while it didn't cut through at power <= 32. Therefore, 35 - 40 is pretty much enough power.
Next, we designed a simple joint to test the kerf clearance. We offset the joint cutting lines from -0.020 inches to +0.015 inches.
Clearance test cutting lines. Blue denotes cutting line, black denotes original lines, and red is annotation scoring.
We cut them out and tried to join them. The joints with -0.020 to 0.000 offsets turned out to be loose. The pair with +0.005 offset provided comfortable friction. The pair with +0.010 offset cannot be joined with bare hand, but I hammered them together. The pair with +0.015 offset cannot be joined at all. Therefore, the kerf is about 0.005 inches thick.
