Grinding real stone - Electrician Talk - Professional ...
Feb 15, 2020· Depending on the situation, I would probably cut spacers from 1/2" PVC conduit and use long bolts or lag bolts into the stone with redheads or something similar like those expansion anchors for lag bolts. Grinding the stone flat sounds like a lot of work, and dust. You could sub it out if you really want to flatten the wall. Sent from my new phone.
