Flex hone and used DLC rocker spindle

This used DLC coated rocker spindle still looks like new. Compare it to any uncoated used rocker spindle. The DLC is slippery and low friction.

Use a flex hone such as 1/2″ dia 320 grit “BRUSH RESEARCH BC1232” (approx $20) to clean any burrs from the rocker ID before installating the DLC coated spindle.
