Engraving perfect circles and arcs just became a one-man operation using the Precision Center Pivot and your Engrave-A-Crete saw with dynamic directional wheels.
The aluminum, 12” diameter pivot provides smooth, accurate action and features a rubber, non-skid, non-marring base that’s heavy enough to remain in place without attaching to the floor. If additional weight is required for intricate patterns, a bucket of weights set atop the bucket tray won’t interfere with maneuverability. Twin connecting tubes stabilize the Precision Center Pivot to eliminate racking.
Located in the exact center is a sighting pin hole and alignment “cross hair” for precise marking and engraving. Parallel connecting tubes extend to attach the pivot to the cutting tool.
Multiple connecting tubes can be added to perfectly cut large arcs and circles. Connecting tube support wheels support long tube extensions, preventing connecting tube drag on the slab.
