Finds the center of any circle quickly
Two angle versions: 90 and 110 degrees
Saves time aligning gears, wheels, and shafts
Marker groove guides a clean line across the part
A staple for makers, hobbyists, and shop workers

You set the tool against a wheel and the marker draws a line straight through the center. This center finder uses simple geometry to bisect any circle: align the inner edges to the outer edge, draw a line, rotate, and where the lines cross is the center.

Two angle versions cover real cases. The 90 degree handles smaller wheels, the 110 degree fits larger ones. The marker groove guides a sharpie or marker for a clean line.

Use it for aligning gears, wheels, robot servos, and any project where a circle needs a center mark.
