I’ve started a new wall just outside of downtown Asheville, at a doctor’s office. A circular drystone wall will surround a maple tree and create a new planting bed. It’s a fun challenge building on this tight a radius. I made a template of the curve out of roofing felt that I use to make sure the stones I am preparing to lay will fit into the circle.
The boys came to visit me the other day.
To get a perfect circle around the tree I rigged up this system of strings, spray paint and a level. The level is tied to the paint wand, ensuring that I keep it plumb as I go around the tree. The trunk isn’t a perfect circle, but it seems that the loop of line I used at that end smoothed out the tree’s contours. I stand back frequently to make sure the wall is staying true and so far it’s been fine.
