Ties to a bound
corner. If the soil is likely to contain stones, longer ties are best because the hole
may need to be enlarged in order to remove the stones. It is easiest to use the same
distance for each tie. Using an even foot makes it easier to remember the distance,
so it needn't be written down. Once the bound has been set, the tape can be used to
measure out from the ties to the top of the bound for setting the drill hole location.
The distance is measured from each tie. The original point will be where the two
distances intersect. Setting a concrete bound can be seen in Fig.
