How to cut stone caps for a curved retaining wall [with photos] | Pretty Purple Door. Curved walls have a greater setback, which causes a coning effect to occur causing your retaining wall to have its tightest radius at the top of the wall which in turn creates the need for a larger radius at the base course.. Draw a line from the mark to the front corner. In most circumstances, making two cuts on one cap and then not cutting the cap on either side produces the most pleasing look. Most curves can be built with no cutting involved. For and outside radius, place two caps on top of the wall, with the back of each cap tight together.
