Mark the underside of the stone cap you are cutting. Spread it all over the base using a rake. Slow arcs of radius 6 metres or more, may be achieved by simply cutting each component flag as a straight line, with the angle of the cut line increasing/decreasing with each successive flag.

Use spray paint to follow along the hose, marking the contours of your path. The flags are laid in such a way that the edge flags project over the proposed line of cut.

When the first option is used, the additional cuts should connect the points of intersection to the edge: when the line of cut is a simple shallow arc, the additional cuts need to be more numerous, dividing the discard piece into sections not more than 100mm wide so that the forces used to break off the discard piece can be more carefully controlled.

Place the stakes every 2 to 3 feet to outline the edges of the walkway more definitively. As can be seen in the diagram opposite, when using a 300mm blade to make a cut that is 150mm long, the blade can only penetrate to a depth of 20mm, which is possibly not enough to give a clean break. However, there is a limit: once a cut edge is less than around 50mm in length, it becomes difficult to justify the extra work involved in making additional cuts.

It should be noted that these convex blades (also known as radius blades or radius cutting blades) are not suitable for full depth or 'plunge' cutting: their shape precludes penetration deeper than a few millimetres, and so additional cutting may be necessary, much as described above, to create weaknesses that can be exploited to reduce the flag to the required curved line-of-cut. Experiment until you have a design that is attractive yet functional. If necessary, use a chisel and rock hammer to trim the flagstones to fit.

The left-hand side of the flagged area consists of an internal curve or arc while the right-hand side is an external curve or arc.

Once scored, individual flags can be lifted out, put into a suitable cutting position, and then cut as required. I guess I'm still concerned because my biggest curve is also at my wall's highest point (24") and I'm afraid that the additional set back caused by the lip (even with a mild curve) will make the wall look off kilter at the curve because the slope in that section won't match the rest of the wall.

Go slowly to make sure the line is cut evenly across the stone. This should leave you 3 inches from ground level. For my project, I drew a gentle curve on the curved stone as a guide for stencil placement and laid the stencils onto the surface, centering them as well as possible considering the uneven edges.
