A continuous round, ring (10) is employed to produce a champher, or beveled, edge (38) on a concrete base (36). Initially concrete (50) is poured into a cylindrical form (20A,20B) and the ring (10) pressed into the top side of the cylindrical form (20A,20B). Excess cement (50) is removed with a trowel (34) and the cement (50) is allowed to harden. After the cement (50) has hardened, the form (20A,20B) is removed and the ring (10) stripped off leaving an attractive and safe champher (38) on the upper edge of the base (50). An alternative embodiment of the ring (100) includes a lip (118) that can be easily gripped so the ring (100) can be removed from the hardened concrete base (36). The gripping lip (118) also prevents the ring (10,100) from falling below the upper rim (24A,24B) of the mold (20A,20B) when the concrete (50) is in its wet, plastic state. |
