I've got a circular retaining wall that is about 12 feet in diameter and I'm getting ready to cut the caps to fit the curve. I've heard two suggestions.
1. Align the wall caps around the circle, measure the distance between the gaps in in the back of the cap, split the difference on each side and cut.
2. Lay a cap, skip the second position and lay the cap in the third position. Then lay another cap facing the opposite direction in between and make the cut.
Option one is what I was going with, but I didn't know if there is an easier way than having to trim 3/4" off of each side of every block??
