Lapping my Granite Surface Plate to AA Grade

This video shares the processes we took to both measure my granite plate using differential levels, and lapping it into a AA grade spec based on ASME specifications. I am extremely happy with the results and it will exceed my needs! Big thanks to my buddy Lance https://www.26acremaker.com who helped me with this project.
