Honing Stones and Silicon Compound

Goodson’s Honing Stones & Silicon Compound hones high-silicon aluminum alloy blocks with ease. These stones will fit both the Sunnen AN-112 and AN-815 and the Goodson HN-218 and HN-2118HD portable honing mandrels. Use each stone progressively until the final bore size is achieved. To create the final condition, coat the felt set and the honed cylinder surface with the Silicon Compound (AN-30) and lap the cylinders.
