I found a small cheese board and wanted to make a solitaire board. it took about an hour altogether
Step 1: First Things First, an Outline Needs to Be Made. I Simply Used a Ruler and Pen and Made a Grid of 20cm Squares. X~ing Each of the 45 Points of the Grid Points I Marked Them With My Dremels Small Grinder.
Step 2: Widening the Circles; With the Pilot Holes Marked I Widened Out the Holes With the Ball Grinder. As This Was Done Late in an Apartment It Was Loud and I Rushed It.
the dremel was slow and loud so I switched to my drill and a 12mm bit, I dug deeper and then switched back to the grinder.
the dremel softened the edges making it easier for the marbles to sit in.
cleaned it up and got rid of the markings
