A deal came up to cut the 12x12 hexagons in half, my bridge saw will do 3" deep max. So we put our heads together and this is what we got to get the job done. Its a 16hp gas hydraulic driven 24" concrete saw. Takes about 25 minutes to make the cut. I precut the thing on the bridge saw so then the big blade has something to follow and it does it well.
The linear rails I had sitting around for a few years for a just in case project.
