Using PVC pipe to draw curves for saw-cutting
Here’s a novel, fast and inexpensive way of saw-cutting curves on concrete overlays or toppings, using a 1⁄4" diameter PVC pipe, 4" grinder and shop-vac.

Step 1: Transfer at least three points of a curve from the blueprint onto the floor.
Step 2: Use 1⁄4" diameter PVC pipe to join the three points and draw the curve on the floor.
Step 3: With the help of 4" grinder, saw-cut the groove by following the marked line.
